*Topic: *GOES-13 and -15 Visible Calibration Update for the
Month of January 2017

*Date/Time Issued: *January 23, 2017 1545 UTC

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

*Date/Time of Initial Impact: *January 18, 2017 05:14 UTC

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

*Length of Outage: *N/A *

Details and Specifics of Change: *

On 18 January 2017, 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 24 January, two
weeks after the
implementation date (note: this month was issued later than normal).

*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: 2017
Current post-launch calibration coefficient: 1.46881
Date: 2016362000000000
Previous post-launch calibration coefficient: 1.46453
Date: 2016334000000000
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: 2017
Current post-launch calibration coefficient: 1.39754
Date: 2016362000000000
Previous post-launch calibration coefficient: 1.39421
Date: 2016334000000000
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.
