Advanced Very High Resolution Radiometer /3 (AVHRR/3)

NSSDCA ID: 1998-030A-01

Mission Name: NOAA 15
Principal Investigator:Mr. Michael P. Weinreb


The Advanced Very High Resolution Radiometer/3 (AVHRR/3) on the Advanced TIROS-N NOAA K-N series of polar orbiting meterological satellites is an improved instrument over previous AVHRRs. The AVHRR/3 adds a sixth channel and is a cross-track scanning instrument providing imaging and radiometric data in the visible, near-IR and infrared of the same area on the Earth. Data from the visible and near-IR channels provide information on vegetation, clouds, snow, and ice. Data from the near-IR and thermal channels provide information on the land and ocean surface temperature and radiative properties of clouds. Only five channels can be transmitted simultaneously with channels 3A and 3B being switched for day/night operation. The instrument produces data in High Resolution Picture Transmission (HRPT) mode at 1.1 km resolution or in Automatic Picture Transmission (APT) mode at a reduced resolution of 4 km. The AVHRR/3 scans 55.4 degrees per scan line on either side of the orbital track and scans 360 lines per minute. The six channels are (1) channel 1, visible (0.58-0.68 microns); (2) channel 2, near-IR (0.725-1.0 microns); (3) channel 3A, near-IR (1.58-1.64); (4) channel 3B, infrared (3.55-3.93 microns; (5) channel 4, infrared (10.3-11.3 microns); and (6) channel 5 (11.5-12.5 microns).
