*Details/Specifics of Change: *
On 12 July 2016, 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 26 July, two weeks after the implementation
date.
*GOES-15:*
The following update of the calibration coefficients, based on
post-launch vicarious calibration at NOAA/NESDIS/STAR, are recommended
for the currently operational GOES Imager visible channel. These
coefficients are to be implemented on the second Tuesday of the Update
Month listed below and optimal on the last Tuesday of the Update Month
(inthe middle of the two scheduled updates).
Satellite: GOES-15
Update Month: July
Update Year: 2016
Current post-launch calibration coefficient:1.44225
Date:2016180000000000
Previous post-launch calibration coefficient:1.43773
Date:2016152000000000
Initial calibration coefficient: 1.0
Initial calibration date: 2001269000000000
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.

post-launch
vicarious calibration at NOAA/NESDIS/STAR, are recommended for
the currently
operational GOES Imager visible channel. These coefficients are
