3. Outline GCC Activities EP Guidance Discussions at EP meeting
Summary of Actions

4. GCC presented on the following activities
GCC Activities
Global participation in GSICS activities
GSICS Quarterly Newsletter
Meeting Support
GSICS Product Status
New products accepted in past year
GSICS Action Tracker
New Feature added on Product Catalog
GSICS References

5. EP guidance was sought on the following topics:
Approval of the new format of Product Catalog, available at
GPPA - Demo Phase -: A comprehensive discussion on GPPA ensued ( see following slides)
New exceptions a) RAC files –single/multiple, applied to DCC product.
J1-CrIS and IASI-B are not yet GSICS references.
GSICS Cloud, Internet and Wiki presence : Actions were generated to address this point
NOAA-GCC-GDWG <-> WMO need collaboration/cross visits to harmonize cloud usage and meet future demands of data warehousing and publishing.
4. GSICS, 3-G and WIGOS: Actions were generated to address this point
There has been increased collaboration between GNSS – GRUAN – GSICS. Within the WIGOS system this has made a highly positive impact contributing to vital validation activities of L1B Climate records and direct instrument monitoring particularly in the Microwave and IR wavelengths.
We now have GSICS POC in GRUAN and GRUAN POC in GSICS
Should regular updates be provided to EP on 3G and WIGOS ?
Should we have a GSICS POC in WIGOS ?

12. 2. Fast Tracking maturity. EP Guidance
EP Guidance needed for GPPA A. For Classical products we can wave off the Users’ Guide requirement. Perhaps prepare a common users’ guide. B. A common ATBD also can be prepared.
This would lessen documentation required in GPPA (Might help MTSAT-2 Himawari 8/9 and COMS).
We could seek of these information:
Uncertainty estimates OR
Regular use of inter-calibration coefficients OR
Maturity of L1B radiances (Mitch Goldberg et al.)
EP was sought on assigning maturity to products that have stopped being generated.

13. 2. GPPA Discussions and Actions
Discussion: Relax the requirement for a User Guide for classical GSICS products.
Discussion: Relax the requirement for Uncertainty analysis. This can be complimented by an Impact Report showing the benefit of using Cross-Calibration products. Promotion could weigh whether Input L1B measurements are taken from Operational data processing streams of host agencies.
A.GCC
GCC to simplify and stream line GPPA checklist and share it with members to fast track maturity; Start with KMA and JMA.
GCC
A.GCC
GCC to provide recommendations on new processing and science maturity levels for GSICS products and services

14. 3. GSICS Cloud, Internet and Wiki presence
The GCC registered the gsicswiki.net domain for the next five years. It is envisaged that this will help to reduce the overhead of porting the GSICS wiki from the UMD Atmospheric and Oceanic Science Department to the UMD ESSIC.
GCC-GDWG-NOAA maintain the GSICS Product Catalog. WMO is moving to a cloud infrastructure.
NOAA has access to cloud infrastructure ( Azure, Google, AWS). Its accessibility for GSICS is being explored.
A.WMO
WMO to provide information on WMO cloud to NOAA-GDWG. Information sought includes(Visibility, Ability to download data, Disk Space and Redundancy)
WMO

15. 4. GSICS, 3-G and WIGOS
In the lead up to the Microwave Subgroup’s initiative with GRUAN with the aim of using GRUAN measurements to validate GSICS monitoring, the EP gave the following action to the GCC.
A.GCC
GCC to contact GRUAN POC in GSICS ( Tony/Ralph/Cheng-Zhi) to submit yearly updates on 3G (GRUAN-GSICS-GNSS) collaboration to EP GCC EP-20
