Abstract
This paper presents experimental ir horizon profiles of the earth seen from outside the atmosphere. Measurements were made from a capsule which reached 175 km. The attitude was controlled during the whole flight by means of a gyroscopic device. Seven spectral channels were studied, especially: ozone (9.6 μ), CO2 (14–16 μ), the range of atmospheric window (11 μ), and a broad channel (1–50 μ) that was the only one of the first experiment in 1965. The spatial limit of resolution is 0.16°, and the attitude in space of the capsule has been reconstructed with an accuracy equal to 0.05° due to a star mapper. Results are expressed as variations of radiance with respect to tangential height for the different spectral channels.
