Abstract

The results of our 1993 and 1994 experiments at the Tsimlyansk experimental site are given. Spatial variations of small-scale (0.1 m < l < 100 m) temperature inhomogeneities of a steppe surface have been measured. Considerable variations in surface radiation temperature Tr, with variances up to 5 K2, have been found. The spectra of Tr variations are of a one-mode character. The position of the spectral maximum on the wavenumber scale depends on the surface characteristics and may change from year-to-year. Probability density distributions for steppe surface radiation temperature variations are close to a normal distribution.
