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


Date/Time Issued: September 13, 2016 1711Z


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


Date/Time of Initial Impact:   September 13, 2016 0514Z


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


Length of Outage:  N/A

Details and Specifics of Change: 

On 13 September 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 27 September, 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 last Tuesday of the Update Month (in the middle of the two scheduled updates).

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 last Tuesday of the Update Month (in the middle of the two scheduled updates). 

 

Satellite: GOES-13

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.
