  Title:

derived CMAP precipitation

  Source_file:

This product is generated from monthly CPC Merged Analysis of Precipitation Standard observations

  Conventions:

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

  Creation_date:

Fri Mar 4 10:41:55 PST 2016

  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 CPC Merged Analysis of Precipitation (CMAP) excluding NCEP Reanalysis Data Set.

  Spatial resolution:

0.5x0.5 degree
