  2. Shortwave Comparisons • December 03/January 04 and June/July 04 comparisons have been upgraded using CERES edition 2 data • December 04/January 05 comparisons use CERES edition 1 data • Compare first on detector and then on latitude grid basis GIST-23 Offenbach 27-29 April 2005

  15. Conclusions for SW: Ratio Detector DJ04 DJ05 JJ04 32 – 112 .98(.01) .97(.01) .97(.03)* 128 – 160 .95(.01) .95(.01) .96(.02) 193 - 224 .95(.02) .95(.02) .96(.03) *eyeball guess GIST-23 Offenbach 27-29 April 2005

  16. Conclusions for SW: Differences • Detector No. DJ04 & DJ05: JJ04: 1 - 31 Inadequate sampling 32 – 112 -2 (1) 48 – 224 -2.5 (2) 128 – 192 -4 (2) 193 – 240 -7 (4) 240 – 256 Inadequate sampling GIST-23 Offenbach 27-29 April 2005

  17. Conclusions for SW: Difference in Latitude Bins DJ04 -3.3 W-m-2-Sr-1 DJ05 -3.1 JJ04 -2.3 In NH many grids are within 1 s of 0 In SH many grid are below 0 by > 1 s GIST-23 Offenbach 27-29 April 2005

  18. Conclusions for SW • Detector to Detector variation is slow in Northern Hemi. and more erratic in SH for both DJ04 and JJ04. • DJ04 and DJ05 agree very well, thus Any degradation of GERB SW matches CERES ed. 1 degradation. Detector to Detector variations match between DJ04 and DJ05, indicating that the variations are real and not sampling noise. GIST-23 Offenbach 27-29 April 2005
