GCIP/NESOB-97 Land Characterization: EDC Conterminous US AVHRR
In May 1987, the U.S. Geological Survey's EROS Data Center (EDC) began real-time reception of Advanced Very High Resolution Radiometer (AVHRR) data from operational NOAA polar orbiting satellites. EDC receives AVHRR High Resolution Picture Transmission (HRPT) data for the entire conterminous United States, southern Canada, and northern Mexico. The AVHRR Data Acquisition and Processing System (ADAPS) includes a tracking antenna, a data receiving subsystem, and a minicomputer with associated peripherals for data processing. Since the 1989 growing season EDC has used the AVHRR (1 km resolution) daily observations to produce weekly and biweekly maximum Normalized Difference Vegetation Index (NDVI) composites of the conterminous United States.
