Roca), WCRP Report 2/2021, World Climate Research Programme (WCRP), Geneva, Switzerland.https://hdl.handle.net/1920/11981https://doi.org/10.13021/gewex.precip.2.3This chapter reviews the use of satellite-derived precipitation datasets to validate climate models, with an emphasis in quality control and normalization. Two checklists are provided: one with the facts regarding the major issues that must be considered in the use of precipitation for validation, and another with recommendations for a proper use of precipitation datasets in model validation, on the line of the ISO normalization rules and quality-assurance of the whole process of validation. Validation of latent heat release, microphysics of precipitation and extremes are considered, and some examples of extensive validations of simulations vs. observations are provided.en-USAttribution 3.0 IGOClimate modelsQuality AssuranceModel validationExtremesBook chapter10.13021/gewex.precip.2.3
