Advanced Very High Resolution Radiometer (AVHRR) Imager
ITT's AVHRR captures important climatology sea surface temperature data that is used here for historical record data profile from 1985-1997.

Every year millions of dollars in crop and property damage are avoided due to accurate weather forecasts made possible by ITT's AVHRR imagery. Images produced by POES primary instrument, AVHRR, are used to track severe storms and then combined with the data produced by ITT's on-board Sounder to accurately forecast the path and severity of storms. In addition to storm tracking the AVHRR imager is useful for mapping water boundaries, lake-volume fluctuations, snow-melt, vegetation indexes and sea-surface temperature monitoring.
ITT's first AVHRR was first carried on TIROS-N,launched in October 1978 as a 4-channel radiometer, later to be improved to a 5-channel instrument-AVHRR/2 carried on NOAA-7, launched in June 1981.
Today the third generation AVHRR/3 is internationally recognized as the operational imager for global weather data. It has resulted in improvements in performance and operational capabilities, and improved spectral performance: low light energy detection, snow/ice discrimination, forest fire detection, sea surface temperature, and global vegetation index. This 6 multi spectral channel radiometer started its operational flight on NOAA-15, launched in May 1998 and is also on board MetOP-1, Europe's first meteorological operational polar orbiting (MetOP) satellite.
