International Datasets

• MSWEP (Multi-Source Weighted-Ensem­ble Pre­cip­i­ta­tion) is a new global ter­res­trial pre­cip­i­ta­tion (P) dataset (1979–2015) with a high 3-hourly tem­po­ral and 0.25° spa­tial res­o­lu­tion. The dataset is unique in the sense that it takes advan­tage of a wide range of data sources, includ­ing gauge, satel­lite, and reanaly­sis data, to obtain the best pos­si­ble P esti­mates at global scale.
