Details

On 13 January 2015, 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 27 January, 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 fourth Tuesday of the Update Month (in
the middle of the two scheduled updates).

Satellite: GOES-15
Update Month: January
Update Year: 2015
Current post-launch calibration coefficient:  1.37800
Date: 2014357000000000
Previous post-launch calibration coefficient:  1.37145
Date: 2014323000000000
Initial calibration coefficient: 1.0
Initial calibration date: 2001269000000000


GOES-13:

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 fourth Tuesday of the Update Month (in
the middle of the two scheduled updates).

Satellite: GOES-13
Update Month: January
Update Year: 2015
Current post-launch calibration coefficient:  1.31187
Date: 2014357000000000
Previous post-launch calibration coefficient:  1.30840
Date: 2014323000000000
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.
