CERA project information for CORDEX dynamical downscaling data sets on regular geographic latitude-longitude grids
CORDEX dynamical downscaling data sets on regular geographic latitude-longitude grids
CORDEX (http://wcrp-cordex.ipsl.jussieu.fr) is a WCRP initiative to coordinate the downscaling of CMIP5 simulation results produced in support of the IPCC/AR5. About 30 institutes worldwide contributed to the CORDEX data base with more than 20 RCMs in various configurations and versions. CORDEX defined 13 domains (http://wcrp-cordex.ipsl.jussieu.fr/images/pdf/cordex_regions.pdf) with acronyms AFR(Africa), EUR(Europe), ARC(Arctic), ANT(Antarctica), MED(Mediterranean), SAM(South America), CAM(Central America), NAM(North America), WAS(South Asia), EAS(East Asia), CAS(Central Asia), AUS(Austral-Asia), ARB(Mediterranean-North Africa). The priority domain is the African continent. The data are requested to be generated on model grids with an approximate grid cell distance of 50/25/12 km (acronyms -44i/-22i/-11i). More data '- on native model grids '- are provided in project CORDEX_DDS-CMIP5_native-grid. RCM evaluation with the ERA-Interim re-analyses data (1989-2008) is mandatory. Besides, downscaling of historical experiments (1950-2005) and of climate change scenarios RCP 4.5 and 8.5 is requested. Many groups also used RCP 2.6 climate projections. CORDEX data are formatted following the CMIP5 data and metadata protocol where possible. For more details see http://cordex.dmi.dk/joomla/images/CORDEX/cordex_archive_specifications.pdf . A list of the variables requested by CORDEX can be downloaded from this project (CORDEX_variables_requirements_table.pdf). Not all variables will be provided by all RCMs though. Note that 3 and 6 hourly data are also available, however, only at the modelling centres on request.
