This study evaluates the performance of 75 clear-sky global irradiance models against 75
ground stations worldwide covering five major Köppen-Geiger climate classifications and …

Accurate estimations of clear-sky direct normal irradiance (DNIcs) and diffuse horizontal
irradiance (DIFcs) are crucial in solar resources assessment. This study examines 95 and 88 …

This paper is concerned with the choice of clear-sky model in solar forecasting. This issue is
discussed from three perspectives:(1) accessibility,(2) forecast performance, and (3) …

Abstract Solcast (https://solcast. com/) is a global solar forecasting and historical solar
irradiance data company. Their datasets are important to the scientific community as …

High-accuracy solar radiation data are needed in almost every solar energy project for
bankability. Time series of solar irradiance components that spans decades can be supplied …

Aerosol optical depth (AOD) is a highly influential variable in solar resource assessment and
clear-sky radiation modelling. Hence, the accuracy of solar energy estimates ultimately …

In this work, the performance of clear-sky direct normal irradiance (DNI) and global
horizontal irradiance (GHI) predictions generated with three state-of-the-art solar radiation …

The National Solar Radiation Database (NSRDB) offers satellite-derived irradiance over
most of the Americas. The latest version of the NSRDB hosts broadband irradiance …

The clear-sky radiative effect of aerosol–radiation interactions is of relevance for our
understanding of the climate system. The influence of aerosol on the surface energy budget …

The high-performance SPARTA broadband clear-sky solar irradiance model is presented. It
