Commission for Basic Systems (CBS) Technical Conference 2018 Session 4 Item 4.4 – Evolving GDPFS to integrate with the core functions of CSIS Arun KUMAR (Chair ET-OPSLS, USA) Rupa Kumar Kolli (WMO Secretariat) Commission for Basic Systems (CBS) Technical Conference 2018 (Geneva, 26-29 March 2018)

Outline Issues Issue 4.4/1 - Integrate with the core functions of Climate Services Information System (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. - Speak acronyms out

Outline Issues 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

Outline Issues Issue 4.4/3 - Expansion of GPC portfolio to cover sub-seasonal forecasts on global scale

Background on Climate Services Information System (CSIS) : Rupa Kumar Kolli

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

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 To whom (e.g. EC-70, Cg-18, …) Time frame  

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

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 Advice for CBS-MG What By whom Deadline Recommend this activity to move forward and to Inform EC-70 about the coordination between CBS and CCl on the development of the Technical Reference Manual Advice on rec. to EC and Congress To whom (e.g. EC-70, Cg-18, …) Time frame  

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

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) Advice for CBS-MG What By whom Deadline Recommend this activity to move forward and to Inform EC-70 about the development of a new class of GPC in support of sub-seasonal predictions Advice on rec. to EC and Congress To whom (e.g. EC-70, Cg-18, …) Time frame
