  Title:

derived CERES EBAF Radiation

  Source_file:

This product is generated from monthly 1 degree CERES EBAF Radiation observations

  Conventions:

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

  Creation_date:

Thu May 8 23:18:00 PDT 2014

  Approach:

I simply read this variable (sfc_lw_down_all_mon: surface all-sky downward longwave radiation) from original netcdf data file. 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 CERES EBAF radiation dataset.

  Spatial resolution:

0.5x0.5 degree
