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

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.

(Feature Impact) Sixty-five is more than a number. It’s a milestone. A moment to reflect on where you’ve been and look forward with confidence to what comes next. For millions of Americans, turning 65 also means unlocking one of the most valuable benefits you’ve earned: Medicare.
The best is still ahead, and it starts with knowing your options. The official source for Medicare information, Medicare.gov, is here to help with clear, trusted information.
The path to Medicare is not the same for everyone. Some people get Medicare automatically and others have to sign up. It depends on whether you are already getting Social Security. Either way, you’ll want to choose how you get your Medicare coverage.
Get information for your path at Medicare.gov, where you can find out when and how to enroll and explore your coverage options.
Understanding Your Medicare Coverage Options
When you first sign up for Medicare, you choose how to get your coverage. There are two main options: Original MedicareandMedicare Advantage.
Original Medicare is health coverage provided directly by the federal government. It has two parts:
- Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice care and home health care. Most people pay no premium for Part A.
- Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services (like screenings, vaccines and annual wellness visits) and durable medical equipment like wheelchairs and walkers. The standard Part B premium is $202.90 per month and is typically deducted from your Social Security check.
With Original Medicare, you can visit any doctor or hospital in the U.S. that accepts Medicare. You can also add optional coverage to help manage costs:
- Medigap (Supplemental Insurance) helps pay your share of Medicare costs.
- Part D (Prescription Drug Coverage) helps pay for medications.
Medicare Advantage is an alternative to Original Medicare that provides Part A and Part B and is offered by private insurers approved by Medicare. You still pay the Part B premium. Some plans charge an additional premium – though many carry a $0 plan premium and may even help cover part of your Part B cost. Most plans include in Part D drug coverage along with extra benefits like dental, vision and hearing. Keep in mind most plans require you to use doctors within the plan’s network.
5 Steps to Enroll with Confidence
- Use official sources. Go to Medicare.gov or call 1-800-MEDICARE for step-by-step, personalized guidance on coverage and enrollment.
- Start early. You don’t have to wait until your birthday. Explore your options now so you’re ready when your enrollment window opens.
- Know your enrollment path. Your path depends on your circumstances – some people are automatically enrolled and some are not. There are unique steps for people who are still working.
- Avoid late enrollment penalties. Missing your enrollment window can result in a permanent premium penalty for both Part B and Part D. Signing up on time protects your wallet for years to come.
- Compare plans and save. At Medicare.gov, you can compare plan costs side-by-side, based on the specific drugs you take. A quick comparison could save you money each year. You can also confirm your current doctors are in-network before you choose a plan.
Turning 65 is a milestone worth celebrating and it’s the perfect time to focus on what matters most: your health and well-being. That includes eating well, exercising and making sure you have health insurance that fits your needs. There’s no one-size-fits-all plan. What’s important is finding an option that works for you and your health and financial needs.
Start your journey at Medicare.gov – your roadmap to a healthier and confident future.

Join the Fight Against ALS: Register and Make a Difference
(Feature Impact) Every year, doctors tell more than 5,000 Americans they have amyotrophic lateral sclerosis, better known as ALS. It is a life-changing diagnosis.
Still, it’s hard to estimate the total number of ALS cases in the United States. No one knows what causes most cases of ALS, something the U.S. National ALS Registry is working to change.
In honor of ALS Awareness Month, learn more about the registry, how the information is used and how to enroll if you have ALS.
What is ALS?
ALS is a disease that affects the nerve cells that make muscles work in the body. This disease makes the nerve cells stop working and die. The nerves lose the ability to trigger specific muscles, which causes the muscles to become weak and leads to paralysis.
What is the registry?
“The National ALS Registry is a program of, by and for those living with ALS,” said Dr. Paul Mehta, principal investigator of the Registry. “The program collects, manages and analyzes data about people with ALS in the United States. It includes data and information provided by individuals who choose to register and complete the risk factor surveys.”
What is its purpose?
The main purpose is to gather information that can be used in the fight against ALS. The information is used to:
- Estimate the number of new cases of ALS diagnosed each year
- Estimate the number of people who have ALS at any given point in time
- Better understand who gets ALS and what factors affect the disease
- Enhance research that could improve care for people with ALS
How do researchers use the data?
Researchers can use the data to look for disease pattern changes over time and try to identify whether there are common risk factors among people with ALS. Since 2010, the registry has funded more than a dozen studies exploring potential ALS risk factors.
What does participation look like?
Individuals with ALS are encouraged to share their stories, enhancing ALS data and supporting research efforts. People living with ALS can help the National ALS Registry by completing up to 18 risk factor surveys, covering topics such as occupational history and environmental exposures, which help create a more complete picture of their ALS story.
How can someone join?
Anyone living with ALS can enroll. By joining and taking the risk factor surveys, individuals living with ALS can help future generations.
