Abstract
A method of inference of the vertical temperature profiles of the lower atmosphere with the ground-based spectrometer is proposed. The measurements were carried out under clear and overcast sky conditions. Under these conditions the inferred profiles by this method agree with those observed by radio sondes. For cases of partly cloudy sky reliable spectral measurements of radiation are difficult to obtain. In such cases, numerical simulations were carried out and the results were found satisfactory except for warm and humid weather conditions.
