  2. GOES-14 Imager Visible Channel: Initial Post-launch Calibration • Purpose • provide the initial post-launch operational calibration coefficients • Data • GOES-14 Imager visible and Terra MODIS collocation data on 12/23/2009 • Method • Wu, X and F. Sun (2005). Post-launch calibration of GOES Imager visible channel using MODIS, SPIE, Vol. 5882, doi:1117/12.615401.

  3. GOES-14 Imager Visible Channel: Initial Post-launch Calibration Figure. Upper: the accumulated histograms of GOES-MODIS collocated cloud pixels (R > 15%) (black: post-launch cal. GOES data, red: MODIS estimated GOES data, and blue: pre-launch GOES data). Lower: percentages of mismatched cloud pixels at various slope correction The correction factor is the slope correction with lowest mis-matched GOES-MODIS reflectance histogram in the red line data range.

  4. GOES-14 Imager Visible Channel: Initial Post-launch Calibration • Results: • Rpost = Rpre * C1 • Rpost and Rpre are the post-launch and pre-launch calibration reflectance/radiance; C1 = 1.0695is the correction factor. • Also available at http://www.starnesdis.noaa.gov/smcd/spb/fwu/homepage/GOES_Imager_Vis_OpCal.php#g14_init_postlaunch • This result is consistent with initial post-launch calibration for GOES-12/13 (C1 = 1.08/1.12) but is barely in agreement with lunar calibration result for GOES-14 (C1 = 0.99).
