CLPX-Satellite: AVHRR/HRPT Brightness Temperatures and Reflectances  View Catalog Page Entry ID
NSIDC-0152
Summary
This data set includes AVHRR/HRPT (Advanced Very High Resolution Radiometer/High Resolution Picture Transmission) brightness temperatures and reflectances over the NASA Cold Land Processes Field Experiment (CLPX) Large Regional Study Area (LRSA) (NW corner: 42°N, 108.5°W, SE corner: 38.5°N 104°W). Data are gridded to the LRSA at 1.1 km (or 30 arc-second) resolution. Data were collected between November 2001 and May 2003. Reflectance files contain flat binary rasters of 2-byte unsigned integers representing albedo. The brightness temperature files contain 2-byte unsigned integers representing interpolated temperatures in tenths of degrees Kelvin.

Quality
The AVHRR sensor was designed to view cold space and one or more internal warm blackbodies for each scan sequence while in orbit. In general, radiometric calibration involves exposing a radiometer to sources of radiation that have been calibrated against primary or secondary standards and determining a relationship between the output of the radiometer and the intensity of the incident radiation (radiance). All of the radiometers flown on the NOAA/TIROS satellites undergo extensive prelaunch testing and calibration by their manufacturers to characterize their performance.
As the spacecraft moves through its orbit, the expected angular distance between the nadir of adjacent LAC/HRPT scans is approximately 0.0296 degrees of arc, or 3.2914 kilometers, as measured from the center of Earth. The actual value of the average angular distance can vary by up to about 0.1712 kilometers due to variations in satellite height, scan angle, and other factors. The instantaneous field-of-view (IFOV) for all channels is specified to be 1.3 +/- 0.1 milliradians.
