  source_file: This product is generated from monthly FluxNet observations

  title: derived FluxNet

  Approach: I read this variable from individual site data files. Meanwhile I also change the direction of nee (the positive means land sinks co2 from atmosphere now) and convert the unit from umol_m-2_s-1 to Kg C m-2 s-1. Then organized those sites with valid data, and save the data in NetCDF format by each month and each year.

  Temporal resolution: monthly

  General information: This product was derived from site level estimates of GPP and TER from FLUXNET eddy covariance stations.

  Spatial resolution: site observation

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