Forward Trajectory Forecast
This web site is being used for real-time aerosol air quality forecasting. The background basemap is the daily SNPP VIIRS Aerosol Optical Depth EDR (VAOOO), or Terra/Aqua MODIS Aerosol Optical Depth product (MOD04/MYD04), which is used to initialize trajectories which show where the aerosol is expected to move in the next approximately 48 hours. The products are derived from VIIRS and MODIS data acquired and processed directly from the SNPP and Terra/Aqua satellites.
The objective of IDEA-I is an open source, portable version of Infusing satellite Data into Environmental air quality Applications (IDEA) [Al-Saadi, et al., 2005] a satellite based aerosol forecasting, visualization, and data synthesis tool for use by the international air quality forecasting community. IDEA-I supports the Global Earth Observation Systems of Systems (GEOSS) Group on Earth Observations (GEO) Health Societal Benefit Area (SBA) and has been developed within the framework of the GEO Earth Observations in Decision Support Call for Proposals.
