WP9/JRA3: ESM Evaluation: Developing an InfrastructureParticipants:WP Leader: George Tselioudis, Academy of Athens Co-leader: Michael Schulz, IPSLWP Partners:Veronika Eyring, DLRPierre Friedlingstein – U. of ExeterStefan Bakan, MPI-MRalph Doscher, SMHI
OBJECTIVE Create an interdisciplinary infrastructure that will facilitate the scientific evaluation of complex ESMs TASKS Task 1. Survey of methods and problems in ESM evaluation work Task 2. Creation of support structure to facilitate model evaluation tests Task 3. Provision of cataloguing and access services to observational datasets and evaluation tools Task 4. Pilot study on the implementation of evaluation toolkits on ESM output
FIRST YEAR PROGRESS T.1 Survey of methods and problems in ESM evaluation work Questionnaires were sent to all major European ESM groups. ESM evaluation areas have been divided among the partners as follows: AA: Clouds, radiation and precipitation CNRS-IPSL: Aerosols and paleoclimate MPI-MET: Surface fluxes DLR: Atmospheric chemistry U. Exeter: Carbon cycle 87% of questionnaires have been received
Some preliminary remarksAerosol and carbon cycle properties are evaluated using primarily ground based observationsCloud, radiation, and chemistry properties are evaluated using primarily satellite observations Precipitation and surface flux properties are evaluated using a mix of the two dataset types
Frequently reported problemsDiversity of observational data formats reported as the main problem HDF format of satellite data not compatible with model output analysis toolsNetCDF (CMOR comliant if possible) preferred data format
FUTURE STEPSTask 2. Creation of support structure to facilitate model evaluation tests – Put emphasis on process-based evaluationTask 3. Provision of cataloguing and access services to observational datasets and evaluation tools – Include peripheral datasets and tools not commonly used by ESMsTask 4. Pilot study on the implementation of evaluation toolkits on ESM output
