This study reveals the effect of aerosols and water vapor on downward longwave radiation in high mountain region Musala peak, Bulgaria. The investigated period is 01/01/2017 (Jan. 1st 2017) – 30/09/2019 (Sep. 30th 2019). Statistical methods are main tool for discovering relationships between different elements. results indicate that air temperature leading factor radiation, specific h...

This work is based on measurements made at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) central facility from April through June 1997. Five instruments of the ARM SGP central facility have principal roles in this study. The millimeter wave cloud radar (MMCR) is used to measure N and β. The microwave radiometer (MWR) is used to determine when water clouds are overhead;...

Clear-sky downward and upward radiative flux measurements both in the shortand in the longwave spectral range have been used to estimate and analyze the radiation changes at the surface due to the mineral dust advection at a Central Mediterranean site. Then, shortand long-wave radiative fluxes retrieved from the CERES (Clouds and the Earth’s Radiant Energy System) radiometer sensors operating o...

Satellite observations of temperature, water vapor, precipitation and longwave radiation are used to characterize the variation of the tropical hydrologic and energy budgets associated with the El Niño–Southern Oscillation (ENSO). As the tropical oceans warm during an El Niño event, the precipitation intensity, water vapor mass, and temperature of the tropical atmosphere are observed to increas...

A parameterization for the scattering of thermal infrared (longwave) radiation by clouds has been developed based on discrete-ordinate multiple-scattering calculations. The effect of backscattering is folded into the emission of an atmospheric layer and the absorption between levels by scaling the cloud optical thickness. The scaling is a function of the single-scattering albedo and asymmetry f...

Abstract Temperature extremes have been related to anomalies in large-scale circulation, but how these alter the surface energy balance is less clear. Here, we attributed high daytime and nighttime temperatures of eastern Tibetan Plateau (ETP) balance. We find that high-temperature are mainly caused by altered solar radiation, while ones controlled changes downwelling longwave radiation. These ...
