Report from 3rd CORDEX Empirical Statistical Downscaling Workshop

ESD Workshop June2015

CORDEX has held three invitation-only workshops that have developed a program for empirical statistical downscaling (ESD) as part of the greater CORDEX effort to coordinate evaluation and advancement of all downscaling methods.   To date, progress in CORDEX has been largely through downscaling with Multi-GCM / Multi-RCM pairings. ESD methods have different advantages and shortcomings compared to RCMs; however, ESD performance has not been explored as systematically as that of RCMs, creating a gap in overall assessment and applications of downscaling in CORDEX.

The third of these workshops took place 1st-3rd June 2015 at the University of Cape Town, South Africa (see photo of participants above).  The workshop also engaged government policy experts from Tanzania who work in the Ministry of Water, Ministry of Agriculture and in disaster management for the country.   Important issues for the Tanzanian representatives included resilience and long-term trends, information structures to provide seasonal and longer forecasts drought and floods, forecasting for food security and developing localized information for managing weather and climate disasters.   These experts provided valuable user perspective on how downscaling output could be useful within and across government agencies.

Although the workshop consisted primarily of breakout discussions, several presentations during the workshop provided an overview of relevant experiences by workshop participants.  Short presentations discussed limitations of reanalyses when used for ESD or RCMs, evaluation of the skill of GCMs that might provide input to ESD and RCMs, some cross-comparison of RCM-ESD results, and scientific challenges and directions for CORDEX.

The workshop reviewed progress to date on the first CORDEX ESD Experiment and, through breakout groups, developed frameworks for initial documents that will emerge from the workshop series:  a paper on initial results from ESD Experiment 1, a guidance document on ESD implementation and application, and a commentary piece on the current split between widespread use of ESD for climate impacts applications on the one hand and the substantial GCM-RCM coupling for studying regional climate dynamics.

The workshop series has set a foundation for a more cohesive community among the wide diversity of ESD practitioners, and established a more rigorous foundation for the evaluation and uptake of ESD outputs by the scientific community and by stakeholders.  The workshops have also developed a pathway for evaluation of all downscaling methods though a multi-model, multi-method evaluation framework that will likely fit within the planned CORDEX Flagship Pilot Studies.


Report from 3rd SEACLID/CORDEX-SEA Workshop

CORDEX 2015 ManilaPhoto
In the third of a series of five APN sponsored workshops of the Southeast Asia Regional Climate Downscaling SEACLID/CORDEX-SEA Project over 30 participants from across the South East Asia region together with representative from APN, the International Project Office for CORDEX, Hong Kong, Germany and Australasia gathered at the Ateneo de Manila University in the Philippines on the 1st-2nd June 2015.

Fr. Jose Ramon T. Villarin, President of Ateneo de Manila University, Antonia Yulo Loyzaga, Executive Director of the Manila Observatory welcomed the participants to the workshop. Dr Linda Stevenson of APN provided a keynote presentation highlighting the 20th anniversary of the APN, APN’s capacity development agenda, science-policy linkages and the needs of the region, particularly as outlined under the APN’s Climate Adaptation Framework in connection with modelling. CORDEX-SEA Coordinator, Professor Fredolin Tangang then provided an overview of the progress and challenges facing the group before Dr Eleanor O’Rourke, Director of the International Project Office for CORDEX, outlined recent developments in CORDEX strategy, priorities and global activities.

Progress reports from the participating CORDEX-SEA partners; 7 countries in the region plus collaborating partners in Australia, Hong Kong, Sweden, South Korea and the UK, together with new partner Germany; outlined ongoing and completed work and highlighted specific issues being faced.

Considerable time was also devoted to discussion surrounding future activities and how to address the challenges faced within the region. Topics included: implementing a CORDEX-SEA ESGF node; training requirements; bias correction; addressing the lack of human resources and infrastructure in Cambodia and Lao PDR; engaging end users and policy makers; Flagship Pilot Studies; participation in ICRC-CORDEX 2016; and importantly looking forward to the next phase of CORDEX SEA and potential funding options.

Two side meetings, a dinner with regional Civil Society Organisations and a meeting with the Asian Development Bank, focused on building partnerships and developing collaborations with the end user communities in South East Asia.

This workshop followed on from a very successful RegCM Training Workshop 25th-29th May also kindly hosted by Ateneo de Manila University and the Manila Observatory Team and sponsored by ICTP and WCRP. At both the proportion of young scientists was very high and a real working example of the regional climate capacity building at the core of the CORDEX initiative.

The Manila Observatory/Ateneo de Manila University team must be highly commended for not just their immaculate preparation and organisation of both these events but their dedication and kindness to all participants.

Registration for Empirical Statistical Downscaling Workshop now open!

Registration for the 3rd CORDEX empirical statistical downscaling (ESD) workshop is now open for interested participants.  CORDEX ESD activities are described here.  The goals of the workshop are to advance ESD activities within CORDEX, develop means of distilling climate information from multiple sources and engage users of climate information.

The workshop will take place from 1st-3rd June 2015 at the University of Cape Town.  The registration form can be found here.

A block of hotel rooms for this workshop has been reserved until 30 April at the Doubletree Upper Eastside Hotel.  Current price is $95 per person per night, breakfast included - hotel website is found here.
