Wyndly Summer 2023 Pollen Report Methodology
For each city, Wyndly obtained monthly pollen PPMs (pollen grains per cubic meter) for each form (tree, grass, and weed) from February 2022 - May 2023. Data were obtained from Pollen Sense, LLC Automated Particulate Sensors (APS). These sensors automatically detect particulate matter collected from ambient air, and use a neural network algorithm to identify individual pollen species and calculate daily pollen counts.
Yearly averages are calculated by summing the three allergen averages per month of data for a total monthly PPM, summing all monthly total PPMs, then dividing by 12 (month count). Used for per-city average, state average, and total USA average. Season comparisons are done by summing the months of Spring (March, April, May) for 2023 and 2022. If the absolute of the (2023-2022)/2022 is ≤ 0.05, the years were about the same. Otherwise, the more PPM, the worse the season was.
