Service Description: Air Quality Forecast Guidance for 1 hourly Average Daily Maximum PM2.5 (µg/m^3) Concentration Imagery Service's data is created from the numerical prediction model. Concentration units are micrograms per cubic meter. The data in this image service offers predictions for fine particulate matter PM2.5 (µg/m^3). For further information please visit our website at https://vlab.noaa.gov/web/osti-modeling/air-quality . This is a time enabled image service with WMS and WCS capabilities enabled. Forecast guidance is issued twice daily based on 6Z and 12Z model runs. Forecast information is provided in one hour intervals for the subsequent 48-hour period. Client applications may require users to specify time range parameters to view time sliced or loop data.

Update Frequency: The data in this image service updates twice a day at 6Z and at 12Z.
