  source_file: This product is generated from monthly GPCP version 2 precipitation observations

  title: derived GPCP version 2 precipitation

  Approach: I read the monthly global precipitation data from original file, and interpolated from the original resolution in 2.5x2.5 degree to the final one in 0.5x0.5 degree. Meanwhile I also converted the unit from mm/day to Kg m-2 s-1. The final data were saved by each month and each year.

  Temporal resolution: monthly

  General information: This product was derived from GPCP Version 2.2 Combined Precipitation Data Set.

  Spatial resolution: 0.5x0.5 degree
