6. Capacity building and training
Issue 4.4 (1)
Integrate with the core functions of CSIS encompassing climate data, climate monitoring, climate prediction and climate projection, evolve GDPFS to include a class of RSMCs to include (i) centres that maintain Climate Reanalysis, and (ii) centres that provide Climate Monitoring on global scale
References
Background
Under the current Manual on the GDPFS, Regional Climate Centers (RCCs) are specialized centres to deliver
Long-range forecasts
Climate monitoring
Capacity building and training
The Climate Services Information System (CSIS) is the component of the Global Framework for Climate Services (GFCS) concerned with the generation and dissemination of climate information.
RCCs are an essential component of the CSIS
The operational support for the CSIS is provided by the GDPFS
CSIS infrastructure is based on a three tier-strategy
Global Producing Centres
Regional Climate Centres
National Meteorological and Hydrological services

7. Global Producing Centers for Long-range Forecasts
Background
For Long-range forecasts. A three tier strategy is in place in the current GDPFS
Global Producing Centers for Long-range Forecasts
Regional Climate Centers
NMCs
A similar three tier strategy for climate monitoring in support of CSIS is also required.
And therefore, there is a need to evolve GDPFS to have a class of RSMCs to include (i) centres that maintain Climate Reanalysis, and (ii) centres that provide Climate Monitoring on global scale
Rationale
Evolve GDPFS to meet emerging requirements to support CSIS
The inclusion of a new class of RSMCs will also support the concept of the evolution of the current GDPFS towards the Seamless GDPFS
Advice for
CBS-MG
What
By whom
Deadline
Recommend this activity to move forward and to Inform EC-70 about the development of new class of RSMCs in support of climate monitoring
Advice on rec.
to EC and
Congress

8. CSIS operations shall adhere to the WMO Technical Regulations
Issue 4.4 (2)
Support close alignment of the CSIS Technical Reference (being developed by CCl, including the development and deployment of the Climate Services Toolkit), with the elements of the GDPFS by engaging with CCl on the development of the Technical Reference Manual
References
Background
In 2011, Cg-17 established the Climate Services Information System (CSIS) with the guidance that
CSIS operations shall adhere to the WMO Technical Regulations
EC-64 requested CCl to scope out the development of a CSIS Technical Reference Manual with the guidance that
Technical Reference Manual should leverage existing WMO manuals and guides, e.g., GDPFS Manual
The CSIS Technical Reference Manual could provide
Product elements and standards for the climate services
Include technical procedures and organizational structures for the generation and dissemination of climate products and services
The GDPFS, and its Manual, is the single source of technical regulations for all operational data-processing and forecasting systems operated by WMO Members

9. Background
In the development of the CSIS Technical Reference Manual, there is a need to ensure that a close alignment of the CSIS Technical Reference Manual with the technical regulations under the GDPFS is maintained.
Rationale
Ensure that the evolution of GDPFS meets, and supports, emerging CSIS requirements.
Therefore, a close alignment between CSIS Technical Reference Manual and GDPFS will support the evolution of the current GDPFS towards the Seamless GDPFS

10. Under the current Manual on the GDPFS there are
Issue 4.4 (3)
Expansion of GPC portfolio to cover sub-seasonal forecasts on the global scale.
References
Background
Under the current Manual on the GDPFS there are
Global Producing Centres for Long-Range Forecasts (GPC-LRF)
Global Producing Centres for Annual to Decadal Climate Predictions (GPC-ADCP)
GPC-LRFs provide seasonal outlooks
GPC-ADCPs provide the outlooks for annual and decadal time-scales
GPC-LRFs and GPC-ADCPs are further supported by associated Lead Centres that provide coordination among respective GPCs
A similar operational infrastructure (and technical regulations) is lacking for forecasts for sub-seasonal time scale
The operational infrastructure for sub-seasonal forecasts is catching up. For example, currently, there is a joint WWRP-WCRP joint research project on Sub-seasonal to Seasonal (S2S) that is promoting advancement and intake of forecast information on sub-seasonal time-scales

11. Background
Given recent developments in predictions on sub-seasonal time-scales, the concept of GPCs for sub-seasonal forecasts also needs to be advanced to facilitate the availability of coordinated global products as the essential inputs to regional and national operational sub-seasonal forecasting
And therefore, there is a need to evolve GDPFS to include a class of RSMCs for sub-seasonal predictions
Rationale
Evolve GDPFS to meet a service requirement on sub-seasonal time scales and to support the development of the Climate services Information System (CSIS)
