Date/Time Issued: April 10, 2014 2025 UTC

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

Date/Time of Initial Impact: April 08, 2014 05:14 UTC

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

Length of Outage: N/A

Details/Specifics of Change:

On 8 April 2014, 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 April, 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: April

Update Year: 2014

Current post-launch calibration coefficient: 1.35356

Date: 2014083000000000

Previous post-launch calibration coefficient: 1.35017

Date: 2014050000000000

Initial calibration coefficient: 1.0

Initial calibration date: 2001311000000000

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: April

Update Year: 2014

Current post-launch calibration coefficient: 1.29138

Date: 2014083000000000

Previous post-launch calibration coefficient: 1.28986

Date: 2014050000000000

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.
