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

Date/Time Issued: March 8, 2016 2204Z


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


Date/Time of Initial Impact: March 8, 2016 0514Z


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


Length of Outage: N/A

Details and Specifics of Change:  On 8 March 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 22 March, 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, is 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: March

Update Year: 2016

Current post-launch calibration coefficient: 1.42674

Date: 2016055000000000 

Previous post-launch calibration coefficient: 1.42326

Date: 2016026000000000

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, is 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: March

Update Year: 2016

Current post-launch calibration coefficient: 1.35904

Date: 2016055000000000

Previous post-launch calibration coefficient: 1.34998

Date: 2016026000000000 

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: 
R_op =
Coefficient * R_pre where,
R_pre is the pre-launch gain for the channel R_op 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.
