SARAH - A Climate Data Record for Surface Radiation

SARAH 2.1

The CM SAF SARAH 2.1 data record provides surface solar radiation data for the time period from 1983 to 2017. As part of the SARAH data record the surface irradiance, direct horizontal and direct normal radiation as well as the sunshine duration are provided with a high spatial (0.05° x 0.05°) and temporal (30-min, daily, monthly) resolution. More details and access to this Climate Data Record can be found here.

ICDR SEVIRI Radiation

To cover the time period from 2018 to present day, the CM SAF provides the Interim Climate Data Record SEVIRI Radiation, which is based on SARAH-2 methods and consistenly extends the SARAH-2 climate data record; these data are available with a timeliness of less than 5 days. More details and access to this data record can be found here.

Applications and Publications

The CM SAF SARAH data records on surface solar radiation have been used in many studies and for many applications. Some of the applications can be found via the CM SAF Application Webpage. A list of scientific publications using the SARAH data record can be found here. Many publications are about the evaluation of the SARAH data record with surface stations to assess the quality of the SARAH data. Application areas of the data include climate analysis, solar energy assessments, quality control of surface data,  agrometeorology, and climate monitoring.
