Data from the Earth Radiation Budget wide-field-of-view sensors on board the Nimbus-7 satellite during the period 1979–87 indicate a statistically significant downward trend in daytime outgoing longwave radiation (OLR) of up to 14 W m22 decade21 over the Sahara desert region of Africa. Reflected solar radiation shows a positive trend of the same magnitude. No significant trends in temperature o...

Recent projections of global climate changes in response to increasing greenhousegas concentrations in the atmosphere include warming in the Southwestern US and, especially, in the vicinity of Lake Tahoe of from about +3°C to +6°C by end of century and changes in precipitation on the order of 5–10% increases or (more commonly) decreases, depending on the climate model considered. Along with the...

It is of great importance for climate change studies to construct a worldwide, long-term surface downward longwave radiation (Ld, 4–100 μm) dataset. Although number global Ld datasets are available, their low accuracies and coarse spatial resolutions limit applications. This study generated daily dataset with 5-km resolution over the land from 2000 2018 using atmospheric parameters, which inclu...

A radiation model is constructed that includes radiative interactions with atmospheric gases, as well as parameterized treatments of scattering and absorption/emission by cloud droplets and haze particles. A unified treatment of solar and terrestrial radiation is obtained by using identical cloud and haze parameterization procedure for the shortwave and longwave region. The influence of the rel...

Daily net surface radiation fluxes are estimated for Indian land mass at spatial grid intervals of 0.1 degree. Two approaches are employed to obtain daily net radiation for four sample days viz., November 19, 2013, December 16, 2013, January 8, 2014 and March 20, 2014. Both the approaches compute net shortwave and net longwave fluxes, separately and sum them up to obtain net radiation. The firs...
