The objective of this experiment was to obtain vertical temperature and water vapor profiles of the atmosphere at altitudes from 0 to 30 km. The infrared temperature and moisture sounder, SSH-2, was a 16-channel sensor with one channel (3.7 micrometers) in the 3.7 micrometer window, one channel (11.1 micrometers) in the 12-micrometer window, six channels (13.4, 13.7, 14.1, 14.4, 14.8, 15.0 micrometers) in the 15-micrometer CO2 absorption band, and eight channels (12.5, 18.7, 20.1, 22.7, 23.9, 24.5, 25.2, 28.3 micrometers) in the 22- to 30-micrometer rotational water vapor absorption band. The experiment consisted of an optical system, detector and associated electronics, and a scanning mirror. The scanning mirror was stepped across the satellite groundtrack, allowing the sounder to view 25 separate columns of the atmosphere every 32 s over a cross track ground swath of 2204 km. While the scanning mirror was stopped at each of the 25 positions, the channel filters were sequenced through the field of view. The cross track surface resolution was approximately 60 km at nadir. The radiance data were transformed into temperature and water vapor profiles by a mathematical inversion technique. The rms error of the temperature is 2.5 to 3 deg K.
