Abstract
The upper atmosphere ir radiation has been investigated by rockets and satellites. The upper atmosphere radiation has a layer structure, its maximum intensity being observed at altitudes of 150 km, 280 km, 430 km, and 500 km. The radiation energy density in the layers reaches 10−4 erg/cm3 sec, increasing to 10−3 erg/cm3 sec during a magnetic storm. The character of spectral distribution (with maximum in the region of 4.5–8.5 μ) corresponds to radiation of the rotation-vibration bands of diatomic molecules, apparently NO, OH, and CO.Keywords
