An Update on the Collaborative REAnalysis Technical Environment (CREATE)

In order to simplify access to multiple reanalyses, the NASA/NCCS Collaborative REAnalysis Technical Environment (CREATE) has repackaged selected fields from the world’s major reanalysis efforts and published 6-hour and monthly data in the Earth System Grid Federation (ESGF). We will show examples of several new data products and services that have been added and improved to further benefit the research community.

New data products include the Multiple Reanalysis Ensemble (MRE), MRE regridded input data sets, and surface winds at 10 m.

MRE includes the mean and standard deviation of the multiple reanalysis ensemble. To prepare each reanalysis for inclusion into the ensemble, each member was regridded to 0.75 degree and the standard CMIP5 levels for three-dimensional data fields were extracted. The regridded reanalyses are available to aid in reanalysis intercomparison. Early analysis shows that, for the most part, the ensemble mean of selected variables produces a smaller bias than any one ensemble member.

New services include the Earth Data Analytics Service (EDAS), CREATE-V, and GIS.

EDAS allows users to use NCCS high performance computing resources to analyze large reanalysis data sets without the need to download the data. This service is particularly useful for multi-year high frequency reanalysis data sets.

The quick-look visualization tool (CREATE-V) allows users to easily compare different reanalyses and investigate some basic analytics. The MRE mean and standard deviation have been added to CREATE-V and work is on-going to integrate CREATE-V and EDAS to allow more advanced analytics.

Selected CREATE data sets are now available as GIS layers in order to be used in the rapidly expanding GIS community.
