Satellite Sensors

• AVHRR: Advanced Very-High Resolution Radiometer
  • A subset of the HRPT (High Resolution Picture Transmission) data sent by the NOAA series satellites. The sensor provides 1km data.
  • Allows derived sea-surface temperature, NDVI products, as well as reflectance, infra-red and visible channel data.
• MODIS: MODerate resolution Imaging Spectroradiometer
  • A 36-channel sensor, providing 250m, 500m, and 1km data, flown on the Terra-1 and Aqua-1 spacecraft.
• GVAR: GOES VARiable
  • Provided by the GOES-12 spacecraft, the imager data is all 4km.
• SeaWiFS: Sea-viewing Wide Field-of-view Sensor
  • An 8-channel ocean color sensor, at 1km, flown onboard Orbview-2.
• OCM: Ocean Color Monitor
  • 360m ocean color data from the Oceansat-1 satellite, launched by the Indian Space Research Organization.
