Fifth SOFF Steering Committee Meeting

The decisions made during the 5th SOFF Steering Committee Meeting regarding the compliance of stations with GBON requirements. It emphasizes the need to secure an adequate supply of observational data for global NWP centers and highlights the importance of station compliance, data exchange, and maintenance. The document also introduces the concept of SOFF additionality and the framework for achieving full SOFF compliance.

Presentation Transcript

1. 20-21 June Fifth SOFF Steering Committee Meeting SOFF and GBON compliance Decision 5.7

2. Global Basic Observing Network requirements and SOFF scope Securing an adequate supply of observational data to the global NWP centres that serve all countries with forecast and analysis products GBON Variables GBON requirements - per station type Snow Depth Pressure Temp Hum Wind Precip Surface land stations Horizontal resolution: required 200 km, recommended 100 km Observing cycle: 1h Real-time data exchange to WMO Information System (WIS) X X X X X X Upper-air stations operated from land Horizontal resolution: required 500 km, recommended 200 km Vertical resolution: 100m, up to 30 hPa Observing cycle: twice a day Real-time data exchange to WMO Information System (WIS) X X X Marine stations in EEZs Requirements identified Guidance in development: many stations are platforms (ships, buoys) that move/drift Station compliance Based on requirements above Country compliance Station compliance at required horizontal resolution (number of stations required for surface area of country) GBON Technical Regulations: WIGOS Manual (WMO-No. 1160) Cg-Ext(2021)

3. GBON Guide: EC-77 (Feb. 2023) GBON compliance: tools and criteria Security Comms Comms Power Station WMO Information System Data Global NWP centre processing centre WIGOS Data Quality Monitoring System WDQMS Consumables Trained operators Regular maintenance and calibration Incident response Periodic capital investments to extend lifetime WMO and WIGOS Regional Centres Tailored SOFF reporting

4. GBON compliance: WDQMS today GBON surface stations GBON upper air stations

5. GBON compliance: tightened criteria for availability GBON compliance 2023- Global gap 2022 Is a station meeting minimum GBON requirements, to make a significant leap in forecast skill? Does a station exist and is it regularly exchanging data on a daily basis? Monthly Availability (%) 30% 80% (on 60% of days) Timeliness (%) < 5% < 5% Monthly Quality (%) Complete profile (for upper air) < 5% < 5% yes yes

6. SOFF additionality principle, baseline and exemption An intervention may be described as additional if it results in something that would not otherwise have occurred SOFF Operational Manual SOFF support is limited to stations that were not GBON-compliant at time of the WMO GBON Global Gap Analysis A new WMO Global Gap Analysis will be conducted for June 2023 and presented to SC as SOFF additionality baseline Countries can request exemption to additionality principle providing a strong justification, i.e., station operation funded by time-bound development projects that are ending SOFF SC considers and decides on countries request for exemption from SOFF additionality principle

7. SOFF and GBON compliance: Operational elements Readiness Investment Compliance Gap assessed based on GBON requirements Contribution Plan aimed at achieving GBON compliance Investment towards GBON compliance Tested at the end of this phase with WDQMS in commissioning period Steering Committee decides on extension or additional investment in case of force majeure or unforeseen difficulties hindering GBON compliance Result-based finance and peer advisors technical assistance based on GBON station compliance Full SOFF Compliance Phase Framework to be co-developed by SOFF and WMO for a future Steering Committee decision

8. Draft Steering Committee Decision 5.7: SOFF and GBON Compliance The SOFF Steering Committee Adopts the SOFF and GBON Compliance document. Requests the SOFF Secretariat and WMO as the SOFF Technical Authority to coordinate, as needed, the preparation of the complementary operational guidance notes required to ensure smooth implementation of the provisions stated in this document across all the phases of SOFF support. the SOFF Secretariat and WMO as the SOFF Technical Authority to develop a SOFF Compliance Phase Framework, using the provisions described in this document, and drawing on lessons learned from the execution of SOFF Readiness and Investment phase activities, for approval of the SOFF Steering Committee at a future date. Encourages peer advisors, Implementing Entities, WMO Secretariat, and SOFF Secretariat to join efforts to support SOFF beneficiary countries to bring rapidly as many stations as possible into GBON compliance.
