During the International Conference on Regional Climate - CORDEX 2013, a number of scientific challenges emerged including the need for:

  • More rigorous and quantitative assessment of the added value of regional downscaling;
  • Better understanding of processes and phenomena relevant for regional climate change;
  • A broader and more process-based assessment of downscaling techniques and models;
  • Better integration of Empirical-Statistical Downscaling (ESD) within the CORDEX framework;
  • Moving towards very high resolution, convection permitting models;
  • Development of coupled regional earth system models, in particular including the human component (e.g. urbanization, dams, pollution emissions, adaptation etc.)
  • Assessment of the effects of regional forcing, such as land-use change and aerosols;
  • Distillation of actionable information from multiple sources of downscaled projection information; and
  • Better integration of CORDEX with other WCRP programs (e.g. GEWEX)

 

It was recognised that addressing these scientific challenges might be problematic within the general CORDEX framework that employs standard sets of simulations for large domains often encompassing entire continents and surrounding regions. The idea thus emerged to develop more targeted experimental setups, called “Flagship Pilot Studies (FPS)”, which would enable the CORDEX communities to better address a number of the challenges outlined above.

The FPS will focus on sub-continental-scale targeted regions, so as to allow a number of capabilities towards addressing key scientific questions motivated by several issues:

  • Run RCMs at a broad range of resolutions, down to convection-permitting;
  • Promote side-by-side experimental design and evaluations of both statistical and dynamical downscaling techniques at scales more typical of VIA applications;
  • Design targeted experiments aimed at investigating specific regional processes and circulations;
  • Investigate the importance of regional scale forcings (aerosols, land-use change, vegetation etc);
  • Compile and use high quality, high resolution (both spatial and temporal), multi-variable observation datasets for model validation and analysis of processes;
  • Coordinate with specific activities in other WCRP projects, most notably the GEWEX regional hydroclimate projects;
  • Design end-to-end, climate-to-end-user, projects demonstrating the actionable value of downscaled climate change projections;
  • Increase the potential for funding by focusing on specific issues of interest for a certain region

 

In subsequent discussions, the CORDEX Scientific Advisory Team (CORDEX-SAT) recognised that, due to their very nature, FPSs cannot be conceived in general terms but should be driven by the regional CORDEX communities, although sharing common protocols so as to allow easier exchange of know-how. The SAT thus envisions a mechanism of solicitation of FPS proposals to be submitted by the regional communities and assessed by the SAT, with the aid of external experts, for formal CORDEX endorsement. The 'FPS Criteria & Guidelines' document serves to provide guidelines to enable these groups to develop FPS proposals for review and endorsement by the CORDEX SAT according to the criteria listed in the document.

How to submit a FPS proposal

  1. Review the full 'FPS Criteria & Guidelines' document carefully (download here)
  2. Complete the FPS application template (download here)
  3. Submit the completed application to the ipoc@cordex.org

 

Deadlines

There will be 3 deadlines per year for FPS proposals; 15th February, 15th June and 15th October. The third deadline for applications will be Saturday 15th October 2016 and the successful proposals from this round will be presented at the CORDEX web.
