Satellite-based solar resource data are valued for their spatial extensiveness and long temporal record. Validation of such data, including accurate assessment of their uncertainties against reference datasets, is essential to give users confidence in and maximum benefit from the data. More broadly, the international Earth observation from space community estimates many geophysical parameters from satellite data, such as, to name just a few, precipitation, sea surface temperature and atmospheric aerosol amount, and validates them. In particular, the Committee on Earth Observation Satellites (CEOS), an international body that coordinates the use of civilian non-meteorological Earth observing satellites, has made considerable progress in developing standard validation protocols for numerous satellite-derived parameters. These protocols recommend good practices to support the benchmarking and validation of satellite datasets. This paper describes the benefits and development approach of a validation protocol for satellite solar resource data that is being developed under the auspices of the CEOS Working Group on Calibration and Validation (WGCV) Land Product Validation (LPV) subgroup. The protocol development has the support of International Energy Agency (IEA) / Photovoltaic Power Systems (PVPS) / Task 16 Solar resource for high penetration and large scale applications and will build on the work of Task 16 and previous IEA Tasks for solar resource assessment.
