| Abstract |
HRPT is worldwide direct readout of high resolution (1 km) spacecraft parameters and instrument data to ground stations within the footprint of the NOAA polar orbiters. The HRPT service was originally designed to provide timely day and night sea surface temperature, ice, snow and cloud cover information to diverse users, but applications have expanded due to the proliferation of moderately priced equipment and software. HRPT transmissions contain data from nearly all instruments aboard the NOAA polar satellites. The data stream includes information from the High Resolution Infrared Sounder (HIRS), Stratospheric Sounding Unit (SSU), Microwave Sounding Unit (MSU), Solar Backscatter Ultraviolet Radiometer (SBUV), Space Environmental Monitor (SEM), Argos Data Collection unit, TIROS Information Processor (which contains spacecraft attitude data, time codes, housekeeping, telemetry, etc.), and the Advanced Very High Resolution Radiometer (AVHRR).
