英文摘要	Monitoring of climate variables such as air temperature is gaining increasing importance under climate change. This study aimed at developing an hourly gridded 3.5 × 3.5 km air temperature (T air ) data set for entire South Africa. In a Random Forest approach, MSG SEVIRI data from 2010 to 2014 were used and related to T air measured by 78 weather stations. An external validation on new climate stations and years that were not used for model training indicated the ability of the model to predict T air with a RMSE of 2.61 °C and a R 2 of 0.89. The resulting model can be applied to the entire MSG SEVIRI time series since 2004. It hence allows for spatio-temporal pattern analysis as well as for the detection of trends which is relevant in the context of climate change. © 2019 Elsevier B.V.
