It is known that the water vapor content at altitudes of more than 25 km is estimated according to various data within the limits of 20-50 micrometers of precipitated water. There is information that a definite quantity of water vapor is present up to altitudes of 100-120 km and possibly also up to 200 km. However, the question of upper-air vapor distribution in the mesosphere and of the sources supplying it to this altitude range has not been solved up to now. In this work for the purpose of investigating the water vapor at altitudes of more than 20-50 km, a method is used to record the angular radiation distribution of the Earth near the horizon and to determine it by using the altitude of the radiating atmosphere. The selected spectrum range 13-40 micrometers includes CO2 band 600-750cm and the shortwave wing of the H2O rotational band 250-500cm.
