Forward Trajectory Forecast
This web site is being used for high spatial resolution aerosol air quality forecasting using NAM model 3-dimensional wind forecasts. The background basemap is the daily SNPP VIIRS Aerosol Optical Depth based on NOAA Enterprise IVAOT (reduced to VAOOO EDR resolution), which is used to initialize trajectories that show where the aerosol is expected to move in the next approximately 36 hours. In the first frame are shown cloud optical depths from CLAVR-x to indicate where cloudiness has prevented AOD retireval.
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.
