Topic:  Visible calibration update for month of August 2012
 
Date/Time Issued: August 14, 2012 1435 UTC
 
Product(s) or Data Impacted:   All products from visible channel
 
Date/Time of Initial Impact:   August 14, 2012 0514 UTC
 
Date/Time of Expected End:  Until Next Month's Coefficient Update
 
Length of Outage:  N/A

Details and Specifics of Change: 
On 14 August 2012, 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 28 August, two weeks after the implementation date.
 
Satellite: GOES-15
Update Month: August

Current post-launch calibration coefficient:  1.23995
Current calibration date: 2012219000000000
Previous post-launch calibration coefficient:  1.22975
Previous calibration ate: 2012178000000000
Initial calibration coefficient: 1.0
Initial calibration date: 2001311000000000
 
Satellite: GOES-13
Update Month: August
Update Year: 2012
Current post-launch calibration coefficient:  1.23275
Current calibration date: 2012219000000000

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.
