Data Information

  Title:
derived GBAF in 0.5x0.5

  Source_file:
This product is generated from monthly Global Biosphere Amtospher Flux (GBAF) observations

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

  Creation_date:
Tue Jul 28 15:54:11 PDT 2015

  Approach:
I read this variable from data file, and then save the data in NetCDF format by each month and each year. Meanwhile, I also converted the unit from MJoule*m-2*d-1 to Watt/m2.

  Temporal resolution:
monthly

  General information:
This product was derived from Monthly estimates of global biosphere-atmosphere fluxes from Biogeochemistry group at Max Planck Institute in Jena, Germany.

  Spatial resolution:
0.5x0.5 degree

  Derived data code:
