  1. SFC compared with GERB CERES-TISA validation exersize Nov 1, 2005

  2. GERB vs CERES regional fluxes • Grid data into 4°x4° regions to mitigate geolocation errors • Terra FM1 xtrck SFC fluxes or Aqua FM4 xtrck SFC fluxes • Map the instantaneous regional differences for Terra and Aqua • ~20 daytime matches for July 2004 • Note changes between version 2 and 999 • Stratify by LW day, LW night, SW • Biases have been area weighted

  3. Version 2 LW day Terra Version 999

  4. Version 2 LW Day Aqua Version 999

  5. Version 2 LW night Terra Version 999

  6. Version 2 LW night Aqua Version 999

  7. Version 2 Version 999 SW-Terra

  8. Version 2 Version 999 SW-Aqua

  9. GERB vs CERES scatter plots • Compute slope and offset from scatter plot of the monthly matched fluxes between GERB and CERES • Note change in slope and offset between Version 2 and 999

  10. GERB vs Terra-SW GERB vs Aqua-SW

  11. GERB vs Terra-LW day GERB vs Aqua-LW day

  12. GERB vs Terra-LW night GERB vs Aqua-LW night

  13. GERB Version 2 vs 999 • Compare Version 2 and Version 999 • Use one image, July 8, 2004 12:45 UTC • Is the change due to • Calibration change - SW filtered radiance • Spectral changes - SW unfiltered radiance • Scene ID and ADM changes - SW flux

  14. SW filtered radiances July 8, 2004 12:45 UTC

  15. SW unfiltered radiance July 8, 2004 12:45 UTC

  16. SW flux July 8, 2004 12:45 UTC

  17. LW unfiltered radiance July 8, 2004 12:45 UTC

  18. LW Flux July 8, 2004 12:45 UTC
