Sunny with a chance of sneezing – I’m building a tool to forecast pollen levels that will help allergy sufferers know when it’s safe to go outside
Last Updated on October 26, 2025 by Daily News Staff

Do flowers blossoming in spring make you miserable? Are you sworn enemies with fall bloomers like ragweed? If you suffer from pollen allergies, imagine the usefulness of a reliable pollen forecast that could help you manage your symptoms by providing an early warning when pollen conditions are bad.
We’re working on it! As an atmospheric scientist, I study the weather, climate and anything in our Earth’s atmosphere, including pollen. One in three people in the U.S. suffer from allergic rhinitis, otherwise known as “allergies,” and pollen is the most common cause.
While allergic rhinitis is not curable, its symptoms can be successfully treated. Two main methods are medication and pollen avoidance. They both rely on knowing when, where and how much pollen is, and is expected to be, in the air. Many medications work best if taken before symptoms occur. Advance knowledge of pollen allows allergy sufferers to change plans in order to minimize their exposure to pollen.
My colleagues and I are pulling together what we know about how plant biology and meteorology affect the amount of pollen in the air, along with pollen count numbers, to build a reliable pollen forecast.
Counting pollen grain by grain
Allergic symptoms tend to be more severe the higher the concentration of airborne pollen. The amount of pollen in the air is constantly changing, so it would be ideal to monitor pollen in populated areas at regular frequent intervals. In the U.S., the National Allergy Bureau collects, processes and distributes daily pollen concentrations from stations around the country.
Unfortunately, there are fewer than 90 active stations. Of these, many do not count on weekends or outside of the main pollen season. Part of the reason is that these are volunteer-run stations, and pollen monitoring requires significant time and resources.
Pollen is collected using a machine that sucks in air and traps pollen on sticky tape. A trained technician then processes, identifies and counts the tiny pollen grains under a microscope. During the height of pollen season, it may take a few hours for a technician to count the day’s pollen. Automated pollen monitoring systems do exist and would greatly reduce the need for human resources. But for now, these systems are either extremely expensive or have not been evaluated for accuracy.
Building a forecasting model
Pollen that causes allergic reactions is from anemophilous or wind-pollinated plants. Pollen grains contain the male sperm from the plant, an essential component of plant reproduction. Anemophilous plants produce a lot of pollen because they rely on the whims of the wind to carry it to reach the female counterparts of their species to reproduce and grow new plants. The amount of pollen in the air has been rising because climate change is lengthening the pollen season and increasing how much pollen gets produced.
Since we have access to only a limited amount of pollen count data, my colleagues and I leverage what we know about the environment to estimate the amount of pollen in the air. Generally warm, sunny, dry and windy days are correlated with high airborne pollen concentrations, and rainy and humid days with low concentrations.
Plants depend on water and sunlight to grow. The timing of precipitation, temperature and solar radiation can affect a plant’s development and its readiness to flower. Once the plant is ready to flower, environmental variables can determine when pollen is released, how far it travels and how long it remains in the air.
The pollen model my colleagues and I have developed uses these known relationships between meteorology and pollen to estimate airborne pollen. We also include satellite images of vegetation in the model because satellites can detect greening and provide an estimate of the beginning of spring.
Our model can forecast pollen 1 to 14 days in advance for locations where there are pollen stations. But due to the sparsity of pollen stations, we are working on extending the model to forecast in locations with no pollen counts. In those places we use nearby pollen station data, along with localized meteorology, to estimate the pollen.
Although pollen reporting and forecasts do exist in the popular media, their pollen reports differ from observations, and their forecasts are limited only to categories of trees, grasses and weeds. Our forecast can predict for specific pollen types because our model includes information about how each plant type interacts differently with the environment.
A fine-tuned forecast in your pocket
We are collaborating with medical professionals and health scientists to understand the pollen levels associated with increasing severity of allergic symptoms. Our plan is to tailor the forecast to allow patients to better manage their symptoms.
So far, we can accurately forecast for four of the most abundant pollen types in the U.S. only in locations with pollen stations. We are seeking funding to expand to other pollen types and other locations, and we are working on creating a platform to automate the data processing and run the forecast.
Ultimately, we want to provide a forecast every day during pollen season to give allergy sufferers the information they need to manage their symptoms. Allergies are often undertreated and knowledge about self-care is limited, so a reliable pollen forecast that is easy to access – for example via an app on your phone – along with education on allergy management, could really help allergy sufferers.

Keeping the Love of Food with Type 2 Diabetes
Living with Type 2 diabetes often means making adjustments to your daily routine, especially when it comes to food. Although adjusting to life with diabetes may take time, you don’t have to give up your favorite foods and flavors. In fact, it can be an opportunity to discover meals that support your health goals while still enjoying the foods you love.
(Feature Impact) Living with Type 2 diabetes often means making adjustments to your daily routine, especially when it comes to food. Whether you’re living with the condition or supporting someone who is, it can influence everything from meal planning to dinners out and everyday activities. Although adjusting to life with diabetes may take time, you don’t have to give up your favorite foods and flavors. In fact, it can be an opportunity to discover meals that support your health goals while still enjoying the foods you love.
That’s what professional chef and TV show host Kardea Brown did, alongside her husband Bryon Smith, who was recently diagnosed with Type 2 diabetes at age 38.
“When my husband was diagnosed with Type 2 diabetes, it didn’t mean the end of the foods we love,” Brown said. “It meant I had to get creative. I started reimagining my recipes, so they still carry that same soul, that same comfort, just with ingredients that love him back a little better.”
To remove the guesswork about how certain ingredients affect Smith’s glucose levels, the couple relies on Abbott’s FreeStyle Libre 3 Plus sensor with Libre Assist*, a feature within the accompanying Libre app**. The technology provides real-time glucose insights and can help predict how certain foods may affect his glucose^ levels before a meal.
“I open the Libre Assist feature in the app, snap a photo and instantly see how that food might affect me before I even take the first bite,” Smith said. “It even suggests healthier swaps to help lower the impact.”
Small lifestyle changes can also make a difference in diabetes management. Brown recommends:
- Building balanced meals that prioritize non-starchy vegetables, lean proteins and healthy carbs for added fiber.
- Reading labels carefully to ensure you choose ingredients with little or no added sugars.
- Boosting fiber intake with ingredients like lentils, oats, beans and whole fruits.
- Cooking smarter at home by using simple methods like grilling, baking or sauteing with healthy fats, such as olive or canola oil.
- Planning and preparing for success by shopping with a list and planning meals in advance so you always have nutritious ingredients ready to cook.

When Vision Changes: 5 Ways to Navigate What Comes Next
Whether sight changes suddenly or gradually, a question often follows: “Now what?” There is no single way to adjust to vision loss, and the questions can change over time. These five starting points can help you identify what matters most now and where to find support.
(Feature Impact) A change in vision can turn ordinary routines into unfamiliar challenges. A favorite book becomes harder to read. Walking through a familiar neighborhood feels different. A family member offers help, but you may not know how to ask for what you need. Whether sight changes suddenly or gradually, a question often follows: “Now what?”
Medical care is essential, but many people encounter a Grand Canyon-sized gap between clinical care and everyday life with vision loss. Questions arise around getting around safely, continuing to do things you love, talking to family about what is changing and more. The answers take more than information; they require practical guidance, emotional support and connection with people who understand.
“The medical conversation rarely has room for what people are actually grappling with: fear, grief and the very practical question of how to keep living the lives they want,” said Johnjoe Farragher, CEO of Hadley, a nonprofit dedicated to helping adults with vision loss. “Those ‘now what?’ moments are where people need a clear place to begin.”
There is no single way to adjust to vision loss, and the questions can change over time. These five starting points can help you identify what matters most now and where to find support.
Take One Step at a Time
You don’t have to solve every challenge at once. Ask your vision care team about your diagnosis and treatment then think about what is most difficult in daily life right now. It could be reading email, moving safely through your home or using your phone. Choose one concern to address first. A small, useful change can make the next step feel more manageable.
Make Room for the Emotional Side
Vision loss may bring grief, frustration, fear or a change in how you see yourself. Those feelings don’t have to be brushed aside before you can move forward. Share those feelings with someone you trust and seek professional support if you need it. Hearing how others navigated similar changes can help you feel less alone and identify possibilities you may not have imagined.
Find a Trusted Place to Begin
Ask your vision care team about support available in your community. If you’re unsure what to ask for, start with a specific daily challenge on your mind. Offering on-demand guidance, practical tools and opportunities to connect with others living with vision loss, Hadley focuses on life with vision loss beyond the doctor’s office. Its expert-informed guidance and community members address both practical problems and the emotions that come with them, shaped by lived experience. Support is available without cost or waitlists, whether you’re living with vision loss or helping someone you love.
Define Independence on Your Terms
Independence doesn’t have to mean doing everything alone. It may mean finding a new way to do something, choosing a tool that helps or telling family and friends exactly what assistance is useful. Think about a goal that matters to you, whether it’s getting around your home with more confidence or staying involved in a favorite activity, and build from there.
Keep Doing What Matters to You
A change in sight can change how you do things without ending your connection to the people and activities you love. The right adaptations depend on your vision, your interests and your goals.
For instance, when reading gets hard, magnifiers, enlarging fonts, access to free audiobooks and learning braille can make a difference. Passionate home chefs may use tactile or high-contrast labels, well-placed lighting, consistent organization or adaptive tools and techniques to keep cooking with confidence. Assistive technology, low-vision tools and simple adaptations can make everyday routines more accessible and help people stay connected to the activities and relationships that matter most.
When a new “now what?” question comes up, HadleyHelps.org offers a trusted place to start and a path forward.

Mariska Hargitay and Purina Team Up to Help Domestic Violence Survivors Keep Their Pets Safe
Mariska Hargitay and Purina are raising awareness about a heartbreaking reality: Many domestic violence survivors delay escaping abuse because they cannot bring their pets. Discover how the Purple Leash Project is helping families and animals find safety together.
Purple Leash Project takes center stage at U.S. Women’s National Team match, raising awareness about a heartbreaking choice facing abuse survivors and their beloved pets.
By STM Daily News | Lifestyle & Pets | October 12, 2026
WASHINGTON, D.C. — For many people, pets are more than companions. They’re family, providing comfort, unconditional love, and emotional support during life’s most difficult moments. But for survivors of domestic violence, the bond with a beloved pet can create an unexpected obstacle when trying to escape an abusive environment.
Actress and longtime domestic violence advocate Mariska Hargitay joined Purina and the U.S. Women’s National Soccer Team on October 10, 2026, to shine a spotlight on this often-overlooked issue.
During the team’s match against Spain at Audi Field in Washington, D.C., Hargitay served as Purina’s Honorary Captain, helping promote the company’s Purple Leash Project, an initiative designed to help domestic violence survivors find safety without leaving their pets behind.
The appearance was part of Domestic Violence Awareness Month, observed every October.
When Escaping Abuse Means Leaving a Pet Behind
For someone experiencing domestic violence, leaving an abusive relationship can be dangerous and emotionally overwhelming. The situation becomes even more complicated when pets are involved.
According to statistics cited by Purina:
- Only 20% of domestic violence shelters allow pets.
- 48% of survivors delay leaving an abusive situation because they cannot take their pets with them.
These figures illustrate a significant barrier to safety.
For survivors whose pets provide emotional stability and companionship, the possibility of abandoning an animal can be devastating. Some may also fear that an abusive partner will harm a pet left behind.
The Purple Leash Project seeks to eliminate that difficult choice by helping domestic violence shelters become more accommodating to animals.
What Is the Purple Leash Project?
The Purple Leash Project is a partnership between Purina and RedRover, a nonprofit organization dedicated to helping animals and strengthening the human-animal bond.
Through grants and financial assistance, the initiative supports domestic violence shelters and social service organizations by funding:
- Renovations that make shelters pet-friendly.
- On-site and off-site housing for survivors’ pets.
- Essential pet supplies and accommodations.
- Necessary veterinary services for animals entering shelter programs.
According to Purina, the initiative has already provided nearly 70 grants totaling more than $2.2 million across over 30 states.
The company has also established a goal of helping provide one million safe nights for survivors and their pets by the end of 2030.
The ultimate objective is simple: Nobody should have to choose between personal safety and protecting a beloved animal.
Mariska Hargitay Brings the Message to the Soccer Field
Hargitay, widely recognized for portraying Olivia Benson on Law & Order: Special Victims Unit, has spent years advocating for survivors of domestic violence and sexual assault.
Her participation in the U.S. Women’s National Team event brought additional visibility to the Purple Leash Project.
During the pre-match ceremonies, Hargitay participated in the ceremonial coin toss alongside Cassidy, a 75-pound Golden Retriever therapy dog, and Cassidy’s handler, Patrice “Pat” Eller.
Cassidy and Eller are part of a Pet Partners therapy team that helps provide comfort to children who may be required to testify in court.
Their presence illustrated the important role animals can play in helping people cope with traumatic experiences.
“Seeing the Purple Leash Project take the field helped turn the stadium into a powerful show of support for survivors and the pets they love,” Hargitay said in a statement released by Purina.
She also emphasized the importance of reducing the stigma surrounding domestic violence and creating more safe spaces where survivors and their pets can recover together.
A Special Soccer Scarf Supporting Survivors and Pets
To encourage fans to participate in the initiative, Purina and U.S. Soccer introduced a limited-edition Courageous & Comfy Soccer Scarf.
The officially licensed scarf is available through the Purple Leash Project’s online store.
According to Purina, 100% of every scarf purchase is donated to RedRover, supporting the effort to help survivors and their pets remain together.
Fans interested in supporting the initiative can visit:

Bringing Pets Into the Soccer Experience
Beyond raising awareness for domestic violence survivors, Purina used the event to highlight the relationship between sports fans and their pets.
At Audi Field, the company introduced the Purina Club, a temporary pet-friendly seating area where fans could attend the match with their dogs.
The initiative reflects Purina’s growing involvement in soccer, including collaborations with U.S. Soccer and pet-centered activities associated with the 2026 FIFA World Cup.
While these efforts celebrate the companionship pets bring to everyday life, the Purple Leash Project addresses a more serious reality: For some individuals, the ability to remain with their animals can influence whether they can safely leave an abusive situation.
Why the Human-Animal Bond Matters
Anyone who has experienced the companionship of a dog, cat, or another beloved pet understands how deeply animals can become part of a family.
Pets offer familiarity, routine, comfort, and emotional connection. During times of uncertainty, those relationships can become especially meaningful.
For survivors of domestic violence, maintaining that bond can provide an important source of reassurance while rebuilding their lives.
The Purple Leash Project recognizes that protecting survivors and protecting their animals are often interconnected needs.
“At Purina, we believe survivor safety shouldn’t require sacrifice,” said Nina Leigh Krueger, CEO of Purina, in the company’s announcement.
That philosophy is at the heart of the initiative’s mission to expand access to safe, pet-friendly shelter accommodations.
How You Can Help
Supporting survivors and their pets doesn’t necessarily require a major financial commitment.
Individuals can learn more about the Purple Leash Project, support participating organizations, share information about pet-friendly domestic violence shelters, or contribute to nonprofit programs that help families and animals in crisis.
Organizations such as RedRover also provide resources designed to strengthen the human-animal bond and assist animals during emergencies.
Learn more at RedRover.org.
For anyone currently experiencing domestic violence in the United States, confidential assistance is available through the National Domestic Violence Hotline at 1-800-799-SAFE (7233) or TheHotline.org. If immediate danger exists, call 911.
A Safer Future for Survivors and Their Pets
The partnership between Purina, Mariska Hargitay, RedRover, and U.S. Soccer demonstrates how public awareness campaigns can help bring attention to problems that often remain unseen.
For survivors of domestic violence, the path to safety should not mean having to abandon a loyal companion.
And for the pets who depend on their families, remaining together can mean everything.
By helping shelters accommodate animals, the Purple Leash Project is working toward a future where survivors and their pets can escape dangerous situations, find stability, and begin healing together.
