What is Pollen Predictor? Pollen Predictor is the first App to offer 4 days predictive forecast of Pollen levels in Melbourne. Our Predictive system has been developed using software dispersion modelling utilizing years of research and development. Underpinning our comprehensive research is cutting-edge expertise in regional dispersion modelling and exposure analysis. Our air quality professionals collaborated with the firm’s renowned health sciences practitioners to offer world-class pollen predictive assessment. ENVIRON developed a comprehensive pollen predictive model system for Australia to address allergy concerns, particularly hay fever.
About Hayfever People who suffer from nasal allergies (allergic rhinitis) such as hay fever tend to experience a variety of symptoms as a result of their allergy. These may include a runny, itchy or blocked nose, sneezing and sinus discomfort. These symptoms are a result of inflammation in the nasal passages. The nasal inflammation occurs when the nasal passages are exposed to foreign particles (allergens), for example, pollen.
What is a pollen forecast? A pollen forecast is a prediction of what the pollen levels will be in the future, like a weather forecast. Pollen forecasting often has greater value for allergy suffers than a pollen count, because they can use this information to plan their day.
What is a pollen forecast? Typically, pollen counts show what was in the air several days earlier, not whats going to happen today or tomorrow. Pollen forecasting methods consider natural events, besides the recent pollen counts, that will affect future pollen levels. We consider historical pollen counts (which provide predominant pollen and seasonal trend information for a certain area) temperatures, precipitation, and weather forecasts.

Pollen Count Classification Classification Grass Pollen Grains (per cubic metre of air) LOW 0 to 19 MODERATE 20 to 49 HIGH 50 to 99 EXTREME > 100 On High/Extreme days, it is likely that all who are grass pollen-sensitive will experience hayfever symptoms.
Grass PollenThe incidence of grass pollen, estimated by using a Burkard spore trap sitedabove a city building, is correlated with meteorological factors.Pollen incidence is greatest on days with high maximum temperatures andreduced on days of high humidity or rainfall.An analysis of pollen yield and relative abundance of grasses in pastures androadsides has implicated ryegrass (Lolium perenne and L. rigidum) and canarygrass (Phalaris tuberosa) as some of the major sources of atmospheric pollen.

PollenPredictor • PollenPredictor has over 75% accuracy rate in predicting pollen over a 4 day forecast when compared to observed pollen data. • PollenPredictor is being constantly refined to account for changes in climate, wind patterns and pollen movement across Australia.
