A Cloud‐Free Approach to Modeling Daily Downwelling Longwave Irradiance at Global Scale
Parametric modeling of downwelling longwave irradiance under all‐sky conditions (LW↓) typically involves “correcting” a clear‐ (or non‐overcast) sky model estimate using solar‐irradiance‐based proxies of cloud cover in lieu of actual cloud cover given ...

Impact of aerosols and clouds on decadal trends in all-sky solar radiation over the Netherlands (1966–2015) [PDF]
A 50-year hourly data set of global shortwave radiation, cloudiness and visibility over the Netherlands was used to quantify the contribution of aerosols and clouds to the trend in yearly-averaged all-sky radiation (1.81 ± 1.07 W m−2 decade−1). Yearly-

In solar resource assessment, the climatological environment of the target area is objectively quantified by the cloudiness or clear sky index, which is defined as the ratio of global horizontal irradiance to clear sky solar insolation.

A Simple Method for Converting 1-km Resolution Daily Clear-Sky LST into Real LST
Land-surface temperature (LST) plays a key role in the physical processes of surface energy and water balance from local through global scales. The widely used one kilometre resolution daily Moderate Resolution Imaging Spectroradiometer (MODIS) LST ...

Vapor buoyancy increases clear-sky thermal emission
The molar mass of H _2 O (18 g mol ^−1 ) is smaller than that of dry air (29 g mol ^−1 ), which makes humid air lighter than dry air with the same temperature and pressure.

Analysis on the causes of a continuous clear-sky gale event in winter in the Three Gorges Dam Area
A continuous clear-sky gale event (hereinafter referred to as "21·1" clear-sky gale in the dam area) occurs in the Three Gorges Dam Area in the middle January of 2021, which seriously affected the navigation safety of the Yangtze River near the dam area.

Detection of dimming/brightening in Italy from homogenized all-sky and clear-sky surface solar radiation records and underlying causes (1959–2013) [PDF]
A dataset of 54 daily Italian downward surface solar radiation (SSR) records has been set up collecting data for the 1959–2013 period. Special emphasis is given to the quality control and the homogenization of the records in order to ensure the ...

Uncertainties of parameterized surface downward clear-sky shortwave and all-sky longwave radiation. [PDF]
As many environmental models rely on simulating the energy balance at the Earth's surface based on parameterized radiative fluxes, knowledge of the inherent model uncertainties is important.
