KMA GSICS Products review

This page is dedicated to the review of KMA GSICS products. KMA has the following products

• GK2A - IASI/CrIS product ( submitted 11/26/2020)
• COMS-IASI Cross calibration (NRT) Product ( submitted 23/02/2016)

The COMS-IASI product was the first product submitted by KMA for acceptance and went through a full GPPA. All subsequent GSICS products submitted by KMA will/are being treated as a family of instruments and would undergo a shortened GPPA.

GK2A - IASI/CrIS product

On 11/26/2020 KMA submitted the Gk2A Vs IASI/CrIS product for acceptance via the GPPA. The documents submitted are ATBD and GPAF

On 5/3/2024 KMA provided the links to NRT GK2A Vs IASI-B and C /SNPP and N20 CrIS products under the family of instrument catagory. Following a successful review by GDWG Vice Chair Manik Bali, GCC Director Larry Flynn accepted the products in demo phase ( see below)

The products were reviewed using the colab files

GCC Director Larry Flynn communicated via email to EP Chair Bojan Bojkov and GRWG Chair Fangfang Yu that the product has been accepted in Demo Phase. The GSICS Product catalog was subsequently updated.

COMS-IASI Cross calibration (NRT) Product

On 23 Feb 2016 KMA submitted a revised version of the COMS - IASI/AIRS product to the GCC. The files that were submitted are 1) Data File 2) ATBD 3) GPAF .

Daily NRT products can be found here

Masaya Takahashi provided an initial review. Manik Bali offered KMA to use GPPA tools in case they help.

About the product

By- Manik Bali and Hyesook Lee

This is a high value product. Product is well known in the community. Its use in improving SST has been demonstrated. Related work was published in the GSICS Quarterly see here. It has also been published in internationally accepted and respected journals. This product has been generated along the lines of existing GSICS products and GSICS members are familier with the methods used to generate this product. (see below)

Kim, D., M. H. Ahn, and M. Choi, 2015, Inter-comparison of the infrared channels of the meteorological imager onboard COMS and hyperspectral IASI data. Advances in Atmospheric Sciences, 32:7, 1-13, DOI: 10.1007/s00376-014-4124-1.

These publications can be treated as Validation and Impact reports and fulfill an important criterion.

So we can go with less number of reviewers.

Proposed GPPA

Typically three GPAT reviewers are required for a product to be accepted into GSICS Demo Phase. Considering that this product has been

1.Produced routinely at KMA here

2 Peer reviewed publications (listed above) on the product exist

3.Directly used for SST generation at KMA

This condition was relaxed to 2 reviewers. The two reviewers are Manik Bali and Masaya Takahashi. The recommendation of these two reviewers was given to the GRWG/GDWG Chairs who consented to the reccomended the acceptance of the product in the Demo Phase.

Currently Doheyong Kim is the Chair of the GRWG and procedurely he has to reccommend the acceptance of the product in Demo Phase. However since he is from KMA so to avoid any conflict of interest, we have sought Tim Hewison's (EUMETSAT, GRWG Vice Chair) recommendation.

Comments from Masaya (GPAT member) and Manik Bali

Ensure that the Metadata conventions are followed properly. Changes implemented. ( See comments here and response here)

The product is being produced routinely at KMA and pushed to the EUMETSAT GSICS Server ( here) .

Manik Bali Comments-> I conducted a review of the related publications of the product. Also reviewed the product ATBD and GPAF. I found this product extremely usefull to the community at large and would suppor the acceptance of the product into the Demo Phase.

Peter Miu

I also like to congratulate KMA on the COMS/MI product

Tim Hewison Comments-> Sent: 7 April 2017

I would like to congratulate KMA on their progress on this product, and thank Manik for putting together the Wiki topic summarising its progress through the GPPA.

My only additional comment is that it is not clear from the GPAF or ATBD whether any comparisons with AIRS have been included in the product. I would like to see this clarified.

Masaya Takahashi Comments-> Sent: 19 April 2017 07:12

First of all, I would like to congratulate KMA for your great progress on the COMS/MI product. (comments ATBD, GPAF)

Attached here please find my comments from a viewpoint of JMA GPAT member. It would be great if you could update the ATBD before entering Pre-operational Phase - so there is nothing special to do at this stage. On the other hand, I have two questions which I commented in the GPAF.

1) Do you expect that two COMS/MI products using both AIRS and IASI as references? We received only one product which refers IASI. As Tim pointed out, some comparison results may be requested for AIRS one.

2) Do you submit only Near Real Time Correction (NRTC)? If you also plan to submit Re-Analysis Corrections (RAC), would you please provide a sample product?

Once these questions are clarified, I would encourage COMS/MI infrared GSICS Corrections to enter Demonstration Phase.

Dear Masaya, Pete, Tim and Manik

About submitting directly to Pre-Op

Point was discussed and it was thought that this could be applied to COMS (KMA) as well as AHI-IASI (JMA) intercomparision. The idea is to utilize past experience on reaching this stage ( NOAA and EUMETSAT have been) to quickly fulfill the GPPA requirements.
