4. GDWG ToR Updates
(approved at GSICS-EP-18 in 2017)

5. New parts in BLUE
Updated GDWG ToR
Due to the technical nature of WG’s discussions, members are expected to have the following skills
Software Development Life Cycle
Data formats ideally used for the dissemination of satellite data
Meta-data and software coding guidelines, conventions and standards
Expected contribution to GDWG activities
GDWG member
At the level of at least 1 man-month / year contribution. This does NOT include development/operation of agreed GSICS related systems
GSICS member organizations
Expected to commit additional resources for GDWG related systems to ensure developments are realized and systems operate at an acceptable level of service

6. Updated GDWG ToR GDWG shall: New parts in BLUE
[Old] Develop specifications for GSICS product catalogues, data archive systems and data servers in support of GCC
[New] Support the specification of GSICS systems administered by the GCC; GSICS product catalogue, GSICS User Messaging Service, GSICS Wiki, etc.
[Old] Coordinate the development and evolution of GSICS software Systems
[New] Support the specification of GSICS systems and tools administered by the GSICS member and observer organizations

7. GDWG Chairing Two Co-Chairs since Feb. 2015
Peter Miu (EUMETSAT) and Masaya Takahashi (JMA)
Nominal 3-year term over
Reformatting of GDWG chairing was discussed at GSICS-EP-18
New GDWG Chairing: approved at GSICS-EP-18
One Chair: Masaya Takahashi
Two Vice-Chairs: Ashim Mitra (IMD, incoming chair) and Peter Miu (outgoing chair)
Election of the Chair: based on nominations by GDWG members
By GDWG majority decision, a recommendation for the Chair is submitted to GSICS-EP for confirmation

8. GDWG Notable Actions
GDWG Fact Sheet
Big problem in GDWG: limited resources at the level of agency/WG
GDWG activities: not adequately supported by CGMS agencies
2-page GDWG fact sheet: developed at GSICS-EP-18 to emphasize the benefits of GDWG for EACH AGENCY
Who are the members of GDWG?
Why invest in the work done by GDWG?
Emphasizing the importance of GDWG activities by showing GDWG achievements such as GSICS Collaboration Server, Products’ Convention to follow WMO filenaming and netCDF CF Convention
Asking each agency to provide resources for GDWG collaborative activities

9. Updates of GDWG ToR

10. GSICS Collaboration Servers
GDWG Notable Actions
GSICS Collaboration Servers
3 Collaboration Servers (THREDDS) at CMA/EUM/NOAA
KMA/JMA have been sending their GSICS Products to EUM
EUM created new directories for storing JMA/KMA GEO-LEO-IR
Preservation of GSICS Products
Operational Phase products (SEVIRI-IASI IR)
A way to actively “get” products will be used to overcome security constraints
CMA/NOAA created scripts to download the products from Collaboration Servers
Communication w/ ISRO
ISRO launched THREDDS server which stores their GSICS Products
4th Collaboration Server in GSICS?
Need for the communication

11. Use of GitHub for Collaborative Work
GDWG Notable Actions
Use of GitHub for Collaborative Work
GDWG GitHub repository: created by KMA in 2017
To collaboratively maintain/develop GDWG relevant tools/software
GSICS Plotting Tool Project on GitHub
GSICS Plotting Tool: developed at EUMETSAT
Easy comparison among multiple products, but only GEO/LEO-LEO-IR are supported
Requirements for supporting GEO/LEO-LEO-VNIR have been discussed
KMA setup a project to support the new products in collaboration with GDWG members
How to actually work on that?
To be discussed on Day-3!
MSG-3/SEVIRI IR10.8
MSG-4/SEVIRI IR10.8
Himawari-8/AHI B13 (10.4 μm)

12. Instrument Events Logging
GDWG Notable Actions
Instrument Events Logging
CGMS Task Team on Calibration Events Logging
Lead by Rob Roebeling (EUM), mainly composed of GDWG members
Goal: to develop a uniform approach for presenting, logging, and monitoring calibration information across satellite operators
A white paper was submitted to CGMS-45 (June 2017)
1st step: to create stable “Landing Pages” linked from WMO/OSCAR
How to get more traffic from WMO/OSCAR? To be discussed on Day-4
2nd step: to adopt nomenclature and standards for instrument events
Establishing a sub-working group with technical and database experts would be required – to be discussed on Day-4

13. Landing Page at EUMETSAT
Meteosat-10/SEVIRI
Landing Page at EUMETSAT
Hyperlink to Satellite Operator’s Landing Page

2nd step: to adopt nomenclature and standards for instrument events, and develop common DB among space agencies
Establishing a sub-working group with technical and database experts would be required – to be discussed on Day-4

15. Action Tracking GSICS actions have been tracked on the Wiki
Improving the usability of the tracking page was discussed at 2016 Annual Meeting.
Manik Bali (GCC+NOAA GDWG) has been developing/updating new Action Tracking Tool
