“…The first attempt in estimating illuminance from satellite data was conducted in the SATEL_LIGHT project [11]. Later on, S. Janjai's research group proposed a physical approach for calculating the global illuminance from satellite data [12] and displayed the results as illuminance maps. A similar approach has been proposed by He and Ng [13].…”

Satellite-based methods are proposed for the estimation of clear day average hourly illuminance from satellite data under local climate conditions. First, aerosol optical depth (AOD) data collected using a ground-based sun photometer were used to calibrate the satellite remote sensing AOD data. Next, we screened for the factors affecting the illuminance of clear sky and detected three important factors, namely the sine of the solar altitude angle, aerosol optical thickness, and atmospheric precise water content. Finally, based on the AOD data of satellite remote sensing, combined with the local illumination data and meteorological data, a clear sky average hourly illumination model in Chongqing was established via the regression method. There was good agreement between the calculated and the measured values of clear day average hourly illuminance, with a root mean square difference and mean bias difference of 22% and-0.05%, respectively. The model was used to map clear day annual, quarterly, and monthly average hourly illuminance. The maps show the clear day annual, seasonal, and monthly variations of average hourly illuminance in Chongqing.

“…The data span through January 1980 23 to December 2012 of hourly solar irradiance for the nine locations, thus, indicates cumulative year 24 sum of 132 years. This study first investigated the decomposition of the hourly horizontal 25 irradiance into hourly direct and diffuse component using six decomposition models widely 26 referenced in the bibliography. On the hourly decomposition investigation, it was observed that 27 there are no significant differences between the six models for each specific location.…”

In the literature, it 112 was found that some recent papers deal with the solar resource availability based on MAH values in 113 the case of solar illuminance [25,26], solar direct irradiance [27] and solar ultraviolet radiation 114 [28]. The objective of the paper is to evaluate quantitatively the reliability of decomposition models to 117 estimate direct and diffuse solar radiation on two time-bases: hourly and monthly average hourly 118 basis.…”
