Summary

Abstract:
The Nimbus-1 High Resolution Infrared Radiometer (HRIR) Level 1 Brightness Temperature Data Product (HRIRN1L1) contains infrared radiances converted to equivalent black-body temperature or "brightness" temperature values. The HRIR instrument was designed to perform two major functions: first to map the Earth's cloud cover at night to complement the television coverage during the daytime portion of the orbit, and second to measure the temperature of cloud tops and terrain features. The HRIR instrument was launched on the Nimbus-1 satellite and was operational from August 28, 1964 through September 22, 1964 when the spacecraft malfunctioned. Measurements taken during daytime do not reveal true surface temperatures since the radiometer operates in the 3.5 to 4.1 micron region, and reflected solar radiation is added to emitted surface radiation. However, reflected sunlight in this spectral region does not saturate the radiometer output and usable pictures can be made. The Nimbus I HRIR data are stored in a binary TAP format (proprietary tape emulated format). |
