The National Oceanic & Atmospheric Administration (NOAA) operates POES, the Polar Operational Environmental Satellite system. Comprised of several components (namely, the Advanced Very High Resolution Radiometer (AVHRR) and the Tiros Operational Vertical Sounder (TOVS)), these satellites make nearly polar orbits daily, providing global coverage of land, ocean, and atmospheric data. The POES Website includes an overview of the satellite system and lists data types such as vegetation index, sea surface temperature charts, volcanic eruption clouds, and much more. For researchers interested in environmental monitoring using satellite-based data, the POES Webpage will serve as a useful reference point.
