Date/Time Issued: September 8, 2015 1320Z

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

Date/Time of Initial Impact:   September 8, 2015 05:14Z

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

Length of Outage:  N/A

Details and Specifics of Change:  

On 8 September 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 22 September, 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: September
Update Year: 2015
Current post-launch calibration coefficient: 1.40866
Date: 2015237000000000
Previous post-launch calibration coefficient: 1.40363
Date: 2015208000000000
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: September
Update Year: 2015
Current post-launch calibration coefficient: 1.33200
Date: 2015237000000000
Previous post-launch calibration coefficient: 1.32828
Date: 2015208000000000
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.
