How we count and forecast pollen

The pollen and allergies podcast

Dive into a compelling discussion on the art and science of pollen forecasting in this episode. Join Dr Edwin (Ed) Lampugnani as he discusses the pivotal role of accurate pollen predictions and dissects the current state of forecasting technologies.

Beginning with the cornerstone of localized pollen data, Ed underscores its paramount importance for crafting precise forecasts specific to Australia. Delve into the intriguing world of forecasting methodologies, where questions arise about how forecasts can be created without any pollen count data. Ed speculates on alternative models while emphasizing the unmatched accuracy derived from real pollen data. Validation of the accuracy of pollen forecasts takes center stage as the rigorous process of collecting data and confirming the accuracy of the forecasts is explained. Ed sheds light on Melbourne Pollen and Air Health's unwavering commitment to validating forecasts, particularly on high-risk days that are rare yet of paramount significance.

Explore the dynamic collaboration between the Pollen Count and Forecast Service and key players like the Bureau of Meteorology and State Health Departments. Uncover how grass pollen forecasts seamlessly integrate with meteorological data to furnish thunderstorm asthma risk levels.
