Climate Comparisons in the MERRA Atlas
The MERRA Atlas provides monthly, annual, seasonal and climate comparisons among several of the latest atmospheric reanalyses (including ERA-Interim, CFSR, and JRA25) and various global observation datasets.
Reanalysis Comparisons on the WRIT webpages
The NOAA-CIRES Web-based Reanalysis Intercomparison Tools (WRIT) has a prototype plotting/comparison page that is available for testing and commenting by reanalyses.org users and others. To obtain a login to reanalyses.org go to Create New Account.
Observational Studies that examine reanalysis datasets and compare them and observations are described here.
Inter-reanalysis studies that intercompare reanalyses are described here.
WCRP Task Team for the Intercomparison of ReAnalyses (TIRA) - A group of reanalysis developers and users charged to develop a broad reanalysis intercomparison project.
A coordinated activity under the WCRP/SPARC focusing on reanalysis output in the stratosphere, upper troposphere, and lower mesosphere.
