Abstract: | |
The Television and Infrared Operational Satellite (TIROS) Operational Vertical Sounder (TOVS) Level 1B data set is composed of data from the High Resolution Infrared Scanner (HIRS)/2, Microwave Sounding Unit (MSU), and either the Stratospheric Sounding Unit (SSU) or Solar Backscan Ultraviolet Radiometer (SBUV)/2 instruments on the TIROS spacecraft. A Level 1B data set contains the raw instrument values, location of the satellite with respect to the Earth's surface, and the necessary calibration values used to convert the raw instrument values to meaningful numbers. The data are used to calculate pressures, temperatures, water vapor percentages, and ozone concentrations in the atmosphere.
The TOVS Level 1B data sets are composed of the Level 1B data sets of the HIRS/2, MSU, and SSU instruments. The HIRS/2 instrument has detectors in the longwave (15 micron) and shortwave (4.3 micron) areas of the spectrum. The MSU has detectors in the 5.5 micron region of the oxygen emitting region of the spectrum. The SSU has detectors in the 15 micron region for the spectrum. This region is dominated by the CO 2 bands. The MSU has a resolution of about 124 km at the subpoint and it decreases as the instrument looks further away from the subpoint. The SSU has a resolution of 147 km at the subpoint and the resolution decreases as the instrument looks further away from the subpoint. The HIRS/2 has a resolution of about 17 km at the subpoint and its resolution is reduced to about 30 km at the end of a scan. The TOVS 1B data sets serve as the input data to produce the TOVS sounding products.
