Date/Time Issued:  February 12,  2013  ,1330 UTC

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

Date/Time of Initial Impact: February 12, 2013 05:14 UTC

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

Length of Outage:  N/A

Details/Specifics of Change: 

On 12 February 2013, 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 February,
two weeks after the implementation date.

Satellite: GOES-15

Update Month: February
Update Year: 2013
Current post-launch calibration
    coefficient:  1.28819 
Current calibration date:
    2013023000000000
Previous post-launch calibration
    coefficient:  1.28164
Previous calibration ate:
    2012331000000000
Initial calibration coefficient:
    1.0
Initial calibration date:
    2001311000000000
 
Satellite: GOES-13
Update Month: February
Update Year: 2013
Current post-launch calibration
    coefficient:  1.25510 
Current calibration date:
    2013023000000000
Previous post-launch calibration
    coefficient:  1.24747
Previous calibration date:
    2012331000000000
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.
