Date/Time Issued: November 13, 2012 1645 UTC

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

Date/Time of Initial Impact: November 13, 2012 05:14 UTC

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

Details/Specifics of Change:

On 13 November 2012, 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 November, two weeks after the implementation
date.

Satellite: GOES-15

Update Month: November

Update Year: 2012

Current post-launch calibration
    coefficient:  1.27252

Current calibration date:
    2012296000000000

Previous post-launch calibration
    coefficient:  1.26525

Previous calibration ate:
    2012271000000000

Initial calibration coefficient:
    1.0

Initial calibration date:
    2001311000000000

Satellite: GOES-13

Update Month: November

Update Year: 2012

Current post-launch calibration
    coefficient:  1.24466

Current calibration date:
    2012296000000000

Previous post-launch calibration
    coefficient:  1.23992

Previous calibration date:
    2012271000000000

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.
