Advanced Very High Resolution Radiometer

NSSDCA ID: 1980-043A-01

Mission Name: NOAA-B
Principal Investigator:


The NOAA-B Advanced Very High Resolution Radiometer (AVHRR) was a four-channel scanning radiometer capable of providing global daytime and nighttime sea surface temperature, ice, snow, and cloud information. These data were to be obtained on a daily basis for use in weather analysis and forecasting. The multispectral radiometer was to operate in the scanning mode and measure emitted and reflected radiation in the following spectral intervals -- channel 1 (visible), 0.55 to 0.9 micrometer, channel 2 (near IR), 0.725 micrometer to detector cut off around 1.3 micrometers, channel 3 (IR window), 10.5 to 11.5 micrometers, and channel 4 (IR window), 3.55 to 3.93 micrometers. All four channels had a spatial resolution of 1.1 km, and the two IR window channels had a thermal resolution of 0.12 deg k at 300 deg k. The AVHRR was capable of operating in both real-time or recorded modes. Real-time or direct readout data were to be transmitted to ground stations both at low (4 km) resolution via automatic picture transmission (APT) and at high (1 km) resolution via high resolution picture transmission (HRPT). Data recorded on board were to be available for central processing. They were to include global area coverage (GAC) data, have a resolution of 4 km, and local area coverage (LAC) data, which were to contain data from selected portions of each orbit with a 1 km resolution. Identical experiments were flown on the other spacecraft in the ITROS-N/NOAA series.
