Date/Time Issued: May 10, 2016  1552Z

Product(s) or Data Impacted: May 10, 2016 05:14 Z

Date/Time of Initial Impact:  All products from visible channel

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

Length of Event: NA 

Details/Specifics of Change: 

On 10 May 2016, 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 May, 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: May

Update Year: 2016

Current post-launch calibration coefficient: 1.43642
Date: 2016117000000000
Previous post-launch calibration coefficient: 1.43211
Date: 2016082000000000

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: May

Update Year: 2016

Current post-launch calibration coefficient:
    1.36626
Date: 2016117000000000
Previous post-launch calibration coefficient:
    1.36304
Date: 2016082000000000

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.
