Topic: GOES-13 and -15 Visible Calibration Update for Month of January 2013

Date/Time Issued: January 8, 2013 15:00 UTC

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

Date/Time of Initial Impact: January 8, 2013 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 8 January 2013, 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 January, two weeks after the implementation date.

Satellite: GOES-15

Update Month: January

Update Year: 2013

Current post-launch calibration coefficient: 1.28487

Current Date: 2013361000000000

Previous post-launch calibration coefficient: 1.28164

Previous Date: 2012331000000000

Initial calibration coefficient: 1.0

Initial calibration date: 2001311000000000

Satellite: GOES-13

Update Month: January

Update Year: 2013

Current post-launch calibration
    coefficient: 1.25093

Current Date: 2013361000000000

Previous post-launch calibration coefficient: 1.24747

Previous Date: 2012331000000000

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.
