Topic: GOES-13 and -15 Visible Calibration Update for the Month of September 2014

Date/Time Issued: September 9, 2014 1150 UTC

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

Date/Time of Initial Impact: September 9, 2014 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 9 September 2014, 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 23 September, two weeks after the
implementation date.

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: 2014
Current post-launch calibration coefficient:  1.35747
Date: 2014240000000000
Previous post-launch calibration coefficient:  1.35581
Date: 2014209000000000
Initial calibration coefficient: 1.0
Initial calibration date: 2001311000000000

Satellite: GOES-13

Update Month: September
Update Year: 2014
Current post-launch calibration coefficient:  1.30011
Date: 2014240000000000
Previous post-launch calibration coefficient:  1.29836
Date: 2014209000000000
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.
