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

Date/Time Issued: April 10, 2013 14:23 UTC

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

Date/Time of Initial Impact:   April 9, 2013 05:30 UTC

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

Length of Outage:  N/A

Details and Specifics of Change:  

On 9 April 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 2013/099/05:30Z and
2013/099/09:30Z, respectively. These
coefficients are intended to be optimal on 25 April, 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: April
Update Year: 2013
Current post-launch calibration coefficient:  1.29919
Date: 2013080000000000
Previous post-launch calibration coefficient:  1.29634
Date: 2013057000000000
Initial calibration coefficient: 1.0
Initial calibration date: 2001311000000000

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: April
Update Year: 2013
Current post-launch calibration coefficient:  1.25984
Date: 2013080000000000
Previous post-launch calibration coefficient:  1.25796
Date: 2013057000000000
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.
