Topic: GOES-13 and -15 Visible Calibration Update for the Month of February 2016
 

Date/Time Issued: February 9, 2016 1547Z
 

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


Date/Time of Initial Impact: February 9, 2016 0514Z
 

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


Length of Outage: N/A

Details and Specifics of Change: On 9 February 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 23 February, 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: February

Update Year: 2016

Current post-launch calibration coefficient: 1.42326

Date: 2016026000000000 

Previous post-launch calibration coefficient: 1.41897

Date: 2015363000000000

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: February

Update Year: 2016

Current post-launch calibration coefficient: 1.34998

Date: 2016026000000000 

Previous post-launch calibration coefficient: 1.34692

Date: 2015363000000000

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.
