P(論文) Vertical distributions of radiation components were measured by a radiometersonde flown at Syowa Station in 1979. Verification of the measured radiation flux was done in the case of four clear days by comparing to the calculated flux using the data from a routine radiosonde. The measured downward flux coincided with the calculated flux in some cases, in other cases, it was rather smaller than the calculated flux. The measured upward flux was always smaller than the calcuated flux. The discrepancy amounted to 0.06ly/min at most. The reasons for the discrepancies of both fluxes are discussed and some are found to be within the uncertainties of the data used in the calculation. However, there still exist some differences, attributed to the errors of the radiometersonde measurements. An example of the seasonal variation of the cooling rate is also shown. departmental bulletin paper
