Accurate simulation of radiative transfer is a very important aspect in climate modeling. For microclimate models particular, it not only to simulate primary but also secondary fluxes great detail, i.e., emitted longwave and reflected shortwave radiation. As there are always limitations regarding computational effort memory, these commonly implemented using simplified approaches. To overcome si...

This paper gives an update on the observed decadal variability of the earth radiation budget (ERB) using the latest altitude-corrected Earth Radiation Budget Experiment (ERBE)/Earth Radiation Budget Satellite (ERBS) Nonscanner Wide Field of View (WFOV) instrument Edition3 dataset. The effects of the altitude correction are to modify the original reported decadal changes in tropical mean (20°N t...

Peruvian glaciers are important contributors to dry season runoff for agriculture and hydropower, but they at risk of disappearing due climate change. We applied a physically based, energy balance melt model five on-glacier sites within the Cordilleras Blanca Vilcanota. Net shortwave radiation dominates balance, despite this flux being higher in season, rates lower losses from net longwave late...

Abstract. With high emissions of aerosols and the known world's “Third Pole” Tibet Plateau (TP) in East Asia, knowledge on energy budget over this region has been widely concerned. This study first attempts to estimate present-day land balance Asia by combining surface satellite observations as well atmospheric reanalysis Coupled Model Intercomparison Project Phase 6 (CMIP6) simulations. Compar...

The transition zone has been defined as corresponding to atmospheric conditions between cloud-free (albeit containing a suspension of dry particles, i.e. aerosol) and clouds (air highly hydrated droplets or ice crystals). Since significantly affect the infrared radiation reaching Earth's surface, broadband measurements, which are usually performed with pyrgeometers, implicated in some methods p...

introduction: solar net radiation (rn) is one of the most important component which influences soil heat flux, evapotranspiration rate and hydrological cycle. this parameter (rn) is measured based on the difference between downward and upward shortwave (sw) and longwave (lw) irradiances reaching the earth’s surface. field measurements of rn are scarce, expensive and difficult due to the instrum...

The variation of aerosols, especially dust aerosol, in time and space plays an important role in climate forcing studies. Aerosols can effectively reduce land surface longwave emission and re-emit energy at a colder temperature, making estimation of downwelling surface longwave radiation (DSLR) with satellite data difficult. Using the latest atmospheric radiative transfer code (MODTRAN 5.0), we...

In this paper, we discussed several different procedures for calculating irradiation from routine weather measurements and observations. There are between four eight frequently used parameterizations of radiation balance components in meteorological preprocessors, investigated them. First all, the estimated measured solar net irradiance were compared. Afterwards, longwave investigated. Then, re...

[1] In the context of climate feedback associated with temperature change, there exist two potential mechanisms that affect the outgoing longwave radiation (OLR) and the downward longwave radiation (DLR). One is the ‘‘Planck’’ effect that determines the blackbody thermal emission at a considered temperature. The other is the ‘‘absorptivity’’ effect, in which a temperature change causes a change...
