  Approach:

To convert the original data in0.25x0.25 to the final one at 0.5x0.5 degree resolution, Please see conversion steps listed in http://redwood.ess.uci.edu/mingquan/www/ILAMB/Download/CODES/CODES/subroutines/convert/readme_biomass. 3 codes below will be used in these steps. Code 1: http://redwood.ess.uci.edu/mingquan/www/ILAMB/Download/CODES/CODES/subroutines/convert/read-GlobalCarbon.pro Code 2: http://redwood.ess.uci.edu/mingquan/www/ILAMB/Download/CODES/CODES/subroutines/convert/convert-GlobalCarbon.ncl Code 3: http://redwood.ess.uci.edu/mingquan/www/ILAMB/Download/CODES/CODES/subroutines/convert/write-GlobalCarbon.ncl First, I used Code 1 to read above ground and below ground biomass carbon data in quater degree from the original geotiff file

then I used Code 2 to convert unit from the orignal unit of ton C per hectare to the final one of Kg C per m2, meanwhile I summed all available data points for both above and below ground data in each 0.5x0.5 grid cell to obtain the total biomass in 0.5x0.5 degree resolution

finally I used Code 3 to create the final file in netCDF format.

  Temporal resolution:

climatology

  General information:

This product was derived from global biomass carbon stocks data originally in 0.25x0.25 degree resolution.

  Spatial resolution:

0.5x0.5 degree
