  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
