The Chilean government’s energy policy and the power generation sector plans include wind, geothermal, hydro and biomass powerplants in order to introduce renewable energy systems to the country, but they do not mention solar energy to be a part of the plan. This apparent lack of interest in solar energy is partly due to the absence of a valid solar energy database, adequate for energy system planning activities. The only available solar radiation database is relatively old, with measurements taken in 89 stations from the 60’s onwards, obtained with high-uncertainty sensors such as Campbell-Stokes devices and pyranographs. Moreover, not all stations have measured incoming solar radiation for an adequate time span. Here, we compare the existing database of solar radiation in Chile with estimations made with satellite measurements, obtained from the GOES program through collaboration with the Brazilian space institution, INPE. Monthly mean solar energy maps are created from both data sources and compared, using Krigging methods for spatial interpolation. It is found that a maximum 30 percent deviation exist, with snow covers in the Andes Mountains adding additional uncertainty levels. The solar energy levels throughout the country can be considered as high, and it is thought that they are adequate for energy planning given proper diffusion and support by editing a Chilean Solar Atlas.

Abstract. Solar energy applications need global aerosol optical depth (AOD) information to derive historic surface solar irradiance databases from geostationary meteorological satellites reaching back to the 1980's. This paper validates the MATCH/DLR model originating in the climate community against AERONET ground measurements. Hourly or daily mean AOD model output is evaluated individually for all stations in Europe, Africa and the Middle East – an area highly interesting for solar energy applications being partly dominated by high aerosol loads. Overall, a bias of 0.02 and a root-mean-square error (RMSE) of 0.23 are found for daily mean AOD values, while the RMSE increases to 0.28 for hourly mean AOD values. Large differences between various regions and stations are found providing a feedback loop for the aerosol modelling community. The difference in using daily means versus hourly resolved modelling with respect to hourly resolved observations is evaluated. Nowadays state-of-the-art in solar resource assessment relies on monthly turbidity or AOD climatologies while at least hourly resolved irradiance time series are needed by the solar sector. Therefore, the contribution of higher temporally modelled AOD is evaluated.
