Data Information

  creation_date: Thu May 8 23:13:11 PDT 2014

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

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

  title: derived CERES EBAF Radiation

  Approach: I simply read this variable (sfc_lw_up_all_mon: surface all-sky upward 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

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