CICG
3-4 June 2019

2. Plenary Key Resolutions – Topic 4 – Infrastructure
Global Basic Observing Network (GBON) (Doc. 6.1(1))
6.1(1)/1 (Cg-18) - GLOBAL BASIC OBSERVING NETWORK
6.1(1)/2 (Cg-18) - WIGOS STATION IDENTIFIERS
Emerging data issues – WMO Data Conference (Doc.6.2(1), Inf. 6.2(1))
6.2(1)/1 (Cg-18) - EMERGING DATA ISSUES

3. Draft resolution 6.1(1)/1 - GLOBAL BASIC OBSERVING NETWORK; Why is this needed?
Generally, any lack of observations over one area of the globe will limit our ability to understand and predict weather and climate patterns everywhere else.
Weather prediction beyond the 3-4 day range essentially requires observations from the whole world
“In meteorology, ignorance knows no boundaries”
Experiments show that lack of observations in the red area limits 7-10 day forecast skill in green area (example).
Monitoring results showing current exchange of observations for NWP (surface pressure); only green areas meet requirements;
EC-70 requested GBON development in response to this situation

4. What is GBON and who implements it?
GBON represents a new WMO commitment to securing adequate observational input to global NWP systems
GBON will be implemented mostly by the WMO Members
Many WMO Members already comply, so no further action is needed;
Some Members could comply, but observations not currently exchanged; new data exchange practices needed;
Some Members do not have adequate resources to comply; WMO guidance to seek funds for development projects;

5. What is Cg-18 requested to approve, and what happens next?
With draft resolution 6.1(1)/1, Cg-18 will approve the overall Concept for GBON, and
requests
Infrastructure Commission to finalize GBON regulatory material
EC-72 to approve amendment to Manual on WIGOS, including GBON
Following EC-72 the process for nomination of GBON stations will start
Cg-Ext (21) will approve list of GBON stations
GBON will be effective as of July

6. WIGOS Station Identifiers (WSI) Draft resolution 6.1(1)/2
Why is this needed?
The WSI is a system for allocating a unique identier, applicable to all types of observing stations in WIGOS
Many countries have run out of 5 digit IDs and cannot register additional stations
Implementation of WSIs by Members as of July 2016;
Need to streamline the process of assigning WSI to overcome current delays;
Full integration of partner (non-NMHS) observing network require this action
Future-proofing WIGOS: Preparation for registration of IoT contributions (smartphones, cars, ….);

7. WIGOS Station Identifiers (WSI) What is Cg-18 asked to approve? When?
Cg-18 to delegate the assignment of WIGOS Station IDs to contributing organizations contributing, for example:
CGW, GCOS, GAW; many stations operated by non-NHMS entities; trusted program managers can allocate WIGOS IDs;
CTBTO; sister UN organization has agreement with WMO, and operating global network of stations
Come into force July ; preparation and testing activities to start as soon as possible.
