Data Information

  Title:
derived GEWEX SRB Radiation

  Source_file:
This product is generated from monthly 1 degree GEWEX SRB Radiation 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 1 08:16:58 PDT 2014

  Approach:
To obtain surface net radiation from GEWEX SRB radiation data, first I subtracted surface all-sky upward shortwave (sw_sfc_up) from surface all-sky downward shortwave (sw_sfc_dn) to get surface net shortwave radiation(rsns). Using the same way, I also got surface net longwave radiation (rlns = lw_sfc_dn-lw_sfc_up). Then, I added rsns and rlns to get surface net radiation (rns). Meanwhile, the data were also binned from original 1.0x1.0 resolution to final 0.5x0.5 resolution.

  Temporal resolution:
monthly

  General information:
This product was derived from NASA GEWEX SRB radiation dataset.

  Spatial resolution:
0.5x0.5 degree
