Topic:  GOES-13 and -15 Visible Calibration Update for Month of December 2012

 Date/Time Issued: December 11, 2012 18:15 UTC

 Product(s) or Data Impacted:   All products from visible channel

 Date/Time of Initial Impact:   December 11, 2012 05:14 UTC

 Date/Time of Expected End:  Until Next Month's Coefficient Update

 Length of Outage:  N/A
Details and Specifics of Change:  

 On 11 December 2012,
    the following update of the calibration coefficients, based on
    post-launch vicarious calibration at NOAA/NESDIS/STAR,
was implemented for the Imager visible channel of GOES-13 and GOES-15
at 0514Z and 0930Z, respectively. These coefficients are intended to
be optimal on 25 December, two weeks after the
implementation date.
 Satellite: GOES-15
Update Month: December
Update Year: 2012
Current post-launch calibration
    coefficient:  1.28164
Current calibration date:
    2012331000000000
Previous post-launch calibration
    coefficient:  1.27252
Previous calibration ate:
    2012296000000000
Initial calibration coefficient:
    1.0
Initial calibration date:
    2001311000000000
 
Satellite: GOES-13
Update Month: December
Update Year: 2012
Current post-launch calibration
    coefficient:  1.24747
Current calibration date:
    2012331000000000
Previous post-launch calibration
    coefficient:  1.24466
Previous calibration date:
    2012296000000000
Initial calibration coefficient:
    1.0
Initial calibration date:
    2000229000000000
 Some definitions:
The date format is:
    YYYYDDDHHMMSSmmm, where YYYY = year, DDD = day of the year, HH =
    hour, MM = minute, SS = seconds, mmm = msec.
 The coefficient
    provided is a gain that is to be applied to the Visible channel
    counts-to-radiance conversion
 Op_R = Coefficient *
    Pre_R
 where Pre_R is pre-launch
    gain for the channel and Op_R is the new gain -- the gain after the
    coefficient listed as "Current post-launch calibration coefficient"
    is applied.
 The initial coefficient
    has been normalized to 1.0 for the purposes of this post-launch
    calibration.
