To estimate the time delay between the planetary temperature change and the change of the incoming solar radiation fraction absorbed by the ocean and the atmosphere, the analytical energy balance model is presented. The model generalization allows of using averaged data for model parameterization. Using the model, the time delay is investigated on four model cases of absorbed radiation change. The interconnections among the time delay, the planetary thermal inertia and the ocean active layer depth are established

The physical and mathematical model of the planetary heat balance is developed to establish the influence of the atmospheric transmission for the solar radiation in the shortwave spectrum range and for the surface IR radiation in the longwave spectrum range on the Earth's climate. It is shown the possibility of the decreasing of the atmospheric and surface temperatures with the decreasing of the atmospheric transmission for IR spectrum range, and this decreasing can't be equilibrated with the change of the atmospheric transmission for the incoming solar radiation.

ABSTRACT

This paper discusses the thermal regime of the special lunar telescope STL-200, installed on the Russian segment of the International Space Station and intended for monitoring the global albedo of the earth by recording the power of the radiation flux of the earthshine of the moon. An analysis of the proposed thermomechanical layout of the telescope showed that, when it operates with observation cycles lasting 30 min with an interval of 60 min, small thermally induced deviations of the position of the focal plane from the nominal position-a factor of 40 less than the allowable value-occur in the course of all sixteen successive observation sessions. It is shown that the power consumption of the system for ensuring the thermal regime can be economized by optimizing the telescope's operating cyclogram.
