Assessment of solar activity impact on the outgoing long-wave flux for cloudless atmosphere

Based on NCEP/NCAR reanalysis, variations in the integral absorption function and outgoing long-wave flux for cloudless atmosphere during heliophysical disturbances were studied. In our calculations, we used parametrization of the long-wave outgoing radiation for a simple semi-empirical radiation model. The mechanism of solar effect on the troposphere, which is being developed in the ISTP SB RAS, was taken into account. For comparative analysis, distribution maps of radiation characteristics and tropospheric temperature were plotted. Similarity was shown between the spatial structure of temperature field, integral absorption function and the outgoing long-wave flux. Correlation between the temperature and integral absorption function, as long as anticorrelation between the temperature and outgoing long-wave flux might prove validity of the employed parametrization of the mechanism of solar effect on the troposphere.
