Remote sensing of surface and cloud temperatures using the 899-cm interval.
The spectral interval centered at 899 cm(-1) with a bandpass of 8.75 cm(-1) is used for the measurements of surface and cloud-top temperatures from an altitude of 30 km. The continuum and selective absorption contribution to such measurements are discussed. The observations were obtained, using a balloon flight spectrometer, on two occasions: once from Palestine, Texas, in a tropical humid air mass, and once from Sioux Falls, South Dakota, in a cold arctic air mass. The results from these observations are compared with the screen temperatures under the balloon and with special surface temperature measurements made using a thermistor and a radiometer.
