Book Description
A high altitude balloon flight to gather data of the earth's infrared horizon is described. The balloon failed to reach the float altitude of 100,000 feet and therefore, the desired spectral information could not be obtained. (Author).

Book Description
Radiance measurements of the Earth's horizon in three infrared spectral regions were made during two Aerobee rocket flights at White Sands Missile Range, New Mexico. Preliminary results indicate equivalent blackbody radiation temperatures in the CO2 band (14.0 - 15.6 microns) varied from 231K to 239K; in the atmospheric window region (10.2 - 11.8 microns) from 205K to 287K; and in the rotational water vapor band (19.5 - 31.8 microns) from 206K to 239K. Numerous dropouts due to clouds are apparent in the atmospheric window and water vapor bands, while no such effect is evident in the CO2 band. The infrared radiometer, stellar aspect sensor and vehicle attitude control system are described, and actual traces of the horizon profiles and outputs from the stellar aspect system are included. (Author).

Book Description
A horizon detection logic, based on a ratio-of-integrated-radiance concept, which detects the earth's horizon at a relatively stable height under all geographic and meteorological conditions was evaluated by computer simulation on a body of synthesized radiance profiles. An error-sensitivity analysis of the concept was performed, and optimum design parameter values for a sensor were determined. A conceptual design for an improved 15 micron sensor based on this analysis is discussed.
