  Conventions: Please contact Prof. James Randerson (Email: jranders@uci.edu) or Dr. Mingquan Mu (mmu@uci.edu) for any question

  source_file: This product is generated from monthly GPCC version 6 precipitation observations

  title: derived GPCC version 6 precipitation

  Approach: I read the monthly global precipitation data from original file and converted the unit from mm/month 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 GPCC Version 6 Monthly Total Precipitation Data Set.

  Spatial resolution: 0.5x0.5, 1x1 and 2.5x2.5 degree

  Derived data code: http://redwood.ess.uci.edu/mingquan/www/ILAMB/Download/CODES/CODES/subroutines/convert/convert-pr-gpcc.ncl
