Overview

This web site is to be used for real-time aerosol air quality forecasting. The background basemap is the daily Terra MODIS Aerosol Optical Depth product (MOD04), 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 MODIS data acquired and processed directly from the Terra satellite.

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.

IDEA International (IDEA-I) is released as part of the International Moderate Resolution Imaging Spectroradiometer (MODIS) Atmospheric Infrared Sounder (AIRS) Processing Package (IMAPP) [Huang, et al., 2004], and its operational follow-on the Community Satellite Processing Package (CSPP).

IMAPP provides freely distributed science production software for MODIS and AIRS science data products. CSPP provides the same capability for the Visible Infrared Imaging Radiometer Suite (VIIRS) and Cross-track Infrared Sounder (CrIS) on the Suomi National Polar-orbiting Partnership (Suomi NPP).
