GPPA of GSICS Products [ MSG1 and MSG4 Vs IASI ]

On the 11/19/2018 EUMETSAT requested to assign Op maturity to their MSG-1 and MSG-4 Vs IASI Products. While the MSG-1 product has been in the Demo Phase for many years., recently data was generated to fill in any gaps.

After ensuring consistency in data production and investigating quality checks ( that were shared with the Tim Hewison Author of Products) GCC proceeded applying the classical GPPA with new set of recommendations from EP-19 that are aimed at adding efficiency to the maturity assignment process.

These recommendations are

1. GPPA For Family of Instruments ( Accepted)

It is proposed that ...A correction NRT/RAC product can directly be accepted in the Pre-Op phase if

1. The product is created routinely

2. It follows the GSICS format ( filenaming and metadata )

3. The product is made from family of instruments that already create an existing data that has been accepted in the GSICS via the GPPA

2. R.GCC.20180602.1 GCC to relax the requirement of User Guide forclassical GSICS products GCC

Dear EP Members and Group and Subgroup Chairs,

I am happy to announce that MSG4/SEVIRI versus IASI-A/-B IR intercomparison products (near real time corrections) have been accepted as Demonstration GSICS products under the family category extension. We are compiling information to request promotion to Pre-Operational and will be sending that request to the EP for consideration in the near future.


Sincerely,

Lawrence Flynn, GCC Director

Notes

Tim Hewison of Eumetsat has provided, and the GRWG and GDWG Chairs and the GCC Deputy Director have confirmed, the following information regarding the products:

1. MSG-4 SEVERI belongs to the same family as MSG-2/-3 SEVERI.

2. The ATBD and the User Guide that were submitted for MSG-2/-3 are same as those for this product.

3. The Product (Metadata and variables) are same as the MSG-2/-3. Channels have same names and nominal central wavelengths, but slightly different SRFs and band correction coefficients (alpha and beta). The products will work as inputs to the GSICS plotting tool

4. They are now being continuously generated with the same algorithm and through the same operational processing chain as the MSG-2/-3 products. The products are produced regularly on the server and accessible to the public on the EUMETSAT GSICS Server:

http://gsics.eumetsat.int/thredds/catalog/msg4-seviri-metopb-iasi-oper-nrtc/catalog.html

5. They have been validated as part of the initial commissioning and subsequent destorage tests for MSG-4.

The EP gave GCC Director the discretion of acceptance of products in Demonstration Phase – abeyance of the requirement in submission of the documents lies with the GCC Director.

The EP gave GCC Director the discretion of automatic acceptance of products in Demostration Phase for products that fall under the “family category”.
