NOAA National Centers for Environmental Information custodian AVHRR-2 AVHRR-2 Advanced Very High Resolution Radiometer-2 The AVHRR-2 is a multi purpose imaging instrument used for global measurement of cloud cover, sea surface temperature, ice, snow and vegetation cover and characteristics. This instrument was initially carried on NOAA-7 (launched June 1981) and was last flown on NOAA-14 which was decommissioned in 2005. This 5-channel radiometer covering 2 visible and 3 thermal infrared between 0.63 and 12.0 micrometers, has an instantaneous footprint of 1.1 km at the sub satellite point. Additional Information: https://nwpsaf.eu/deliverables/aapp/avhrr_2.html AVHRR-3 AVHRR-3 Advanced Very High Resolution Radiometer-3 The AVHRR-3 is a six channel scanning radiometer providing 3 solar channels in the visible-near infrared region and 3 thermal infrared channels. The AVHRR-3 has two one-micrometer wide channels between 10.3 and 12.5 micrometers. This latest version of AVHRR was first carried on NOAA-15 launched in May 1998 and subsequently in all current NOAA and MetOp platforms. Measuring the same view, this array of diverse wavelengths, after processing, permits multi spectral analysis for more precisely defining hydrologic, oceanographic, and meteorological parameters. Comparison of data from two channels is often used to observe features or measure various environmental parameters. The three channels operating entirely within the infrared band are used to detect the heat radiation from and hence, the temperature of land, water, sea surfaces, and the clouds above them. Additional Information: http://www.ncdc.noaa.gov/oa/pod-guide/ncdc/docs/klm/html/c3/sec3-1.htm MODIS MODIS Moderate Resolution Imaging Spectroradiometer MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). MODIS Technical Specifications Orbit: 705 km, 10:30 a.m. descending node (Terra) or 1:30 p.m. ascending node (Aqua), sun-synchronous, near-polar, circular Scan Rate: 20.3 rpm, cross track Swath Dimensions: 2330 km (cross track) by 10 km (along track at nadir) Telescope: 17.78 cm diam. off-axis, afocal (collimated), with intermediate field stop Size: 1.0 x 1.6 x 1.0 m Weight: 228.7 kg Power: 162.5 W (single orbit average) Data Rate: 10.6 Mbps (peak daytime); 6.1 Mbps (orbital average) Quantization: 12 bits Spatial Resolution: 250 m (bands 1-2); 500 m (bands 3-7); 1000 m (bands 8-36) Design Life: 6 years (From: http://modis.gsfc.nasa.gov/about/index.html) SeaWiFS SeaWiFS Sea-viewing Wide Field-of-view Sensor The purpose of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Project is to provide quantitative data on global ocean bio-optical properties to the Earth science community. Subtle changes in ocean color signify various types and quantities of marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications. The SeaWiFS Project will develop and operate a research data system that will process, calibrate, validate, archive and distribute data received from an Earth-orbiting ocean color sensor. The SeaStar spacecraft, developed by OSC, carries the SeaWiFS instrument and was launched to low Earth orbit on board an extended Pegasus launch vehicle on August 1, 1997. The SeaWiFS instrument will be the only scientific payload on the SeaStar spacecraft. OSC has the sole responsibility for the development, launch, and command and control of the satellite. The development of the SeaWiFS instrument was subcontracted to Hughes/SBRC, but OSC maintains ultimate responsibility for the instrument. The SeaWiFS instrument consists of an optical scanner and an electronics module.

OTHER INFORMATION: https://www.wmo-sat.info/oscar/satellites/view/395 Launched in 1997, OrbView-2 (originally named SeaStar) was the first commercial satellite to provide daily color images of the Earth. Under a unique arrangement with NASA, Orbital designed and built the OrbView-2 satellite, integrating its SeaWiFS sensor. Upon its successful launch, operations of the satellite were handed over to ORBIMAGE (now known as GeoEye) which manages the spacecraft and distributes its data for commercial use. Under a data buy arrangement, NASA procured OrbView-2 SeaWiFS data for scientific research from 1997 through 2004.
