Abstract:
After the first NCEP reanalysis was made available to the community, many researchers collected their own copy and used it for model evaluation. Today we have multiple reanalyses available but each has its own interface and data organization. At the NASA GSFC Climate Model Data Services, in collaboration with others, we have reformatted selections of the major global reanalyses to match the CMIP5 archive on the Earth System Grid Federation (ESGF) and provided a common interface for users. To date, we have prepared the ERA-Interim, MERRA, CFSR, JRA-25, and 20CR. The data have been prepared with two major objectives, 1) to improve the various reanalyses through intercomparison and 2) to assist with climate model validation of the dynamical state fields. This project in conjunction with obs4MIPs provides the community with the latest data customized with a standard interface. I will demonstrate how to take advantage of this new reanalysis resource and present a case study showing the how the partitioning of sensible and latent heat fluxes differ during the 2010 Russian heat wave and the implications of the differences.
