Date/Time Issued: December 13, 2016 1935Z

Product(s) or Data Impacted: December 13, 2016 0514Z

Date/Time of Initial Impact: style="font-size:12pt;font-family:"Times New Roman","serif"">All products from visible channel

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

Length of Event: NA

Details/Specifics of Change:

On 13 December 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 27 December, 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: December
Update Year: 2016
Current post-launch calibration coefficient: 1.46453
Date: 2016334000000000
Previous post-launch calibration coefficient: 1.45999
Date: 2016299000000000
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: December
Update Year: 2016
Current post-launch calibration coefficient: 1.39421
Date: 2016334000000000
Previous post-launch calibration coefficient: 1.39123
Date: 2016299000000000
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.
