Abstract:
In the TIROS II, the satellites spin provides the scan line of the medium resolution radiometer which is then advanced by the orbital motion. The spatial resolution is about 40 miles square when the earth directly beneath the satellite is viewed. The five channels employ bolometer detectors and filters to limit the spectral responses to five bands 6 to 6.5 microns, 8 to 12 microns, 0.2 to 6 microns, 8 to 30 microns, and 0.55 to 0.75 microns. These five bands study, respectively radiation in the water vapor absorption band day and nighttime cloud cover albedo thermal radiation and visual maps for comparison with satellite vidicon pictures. The low resolution non-scanning radiometer measures the earths blackbody temperature and albedo. This radiometer consists of two thermistors, each in the apex of a reflective cone which provides optical gain. One thermistor is black and responds to both ther al and reflected solar radiation. The second responds to thermal but reflects solar radiation. Author
