DATA: Forecast of spatialised pollution concentrations (NO2, O3, PM10,PM2.5) on the Great East for d-1 to J+ 3
Description
Prediction maps of the spatialised concentrations of pollution (NO2, O3, PM10, PM2.5) in ambient air are produced automatically 3 times a day (8:30, 10:30, and 16:30) by the PREVEST modeling chain (WRF/CHIMERE models). These data are derived from a geostatistic correction covering the timeframes from J-1 (measure-based correction) to J0, J+ 1, J+ 2 and J+ 3 (statistical method-based corrections). They contribute to the daily air quality forecast bulletin for the Greater East region, including the determination of the Air Quality Index (AQI). However, these maps may differ from those presented in the daily bulletin following the expertise of forecasters.
