Data Description

The Collaborative REAnalysis Technical Environment (CREATE) Reanalyses Datasets

The CREATE project contains nine global reanalyses (CFSR, ERA5, ERA-Interim, JRA-25, JRA-55, MERRA, MERRA-2, 20CRv2c). Selected variables at model levels are standardized in the CMIP format and maintained. Four of the reanalyses are updated bi-monthly; MERRA and JRA-25 have ended and are superseded by the newer models MERRA-2 and JRA-55, respectively. 20CRv2c ended in 2010.

New products recently added are the MERRA2-ASM assimilation of four 6-hourly 3D variables; CERA-20C, the ECMWF 10-member ensemble of coupled climate reanalyses of the 20th century, and ERA5 monthly means.

CREATE Global Reanalyses

The CREATE project contains seven global reanalyses (CFSR, ERA-Interim, JRA-25, JRA-55, MERRA, MERRA-2, 20CRv2c). Selected variables at model levels are standardized in the CMIP format and maintained. Four of the reanalyses are updated bi-monthly; MERRA and JRA-25  have ended and are superseded by the newer models MERRA-2 and JRA-55, respectively. 20CRv2c ended in 2010.

CREATE Reanalysis Projects 

IAP-UA Global hourly 0.5-degree Surface Air Temperature (SAT) datasets 

The Global hourly 0.5-degree Surface Air Temperature (SAT) datasets were developed by Aihui Wang of the Institute of Atmospheric Physics, Beijing, China,Xubin Zeng, The University of Arizona, Tucson, Arizona;  based on four reanalysis products [Modern-Era Retrospective Analysis for Research and Applications (MERRA for 1979-2009), 40-year ECMWF Re-Analysis (ERA-40 for 1958-2001), ECMWF Interim Re-Analysis (ERA-Interim for 1979-2009), and NCEP/NCAR reanalysis for 1948-2009)] and the Climate Research Unit Time Series version 3.10 (CRU TS3.10) for 1948-2009.

Collaborative REAnalysis Technical Environment - Multiple Reanalysis Ensemble (CREATE-MRE)

Climate and Ocean: Variability, Predictability and Change (CLIVAR) Global Synthesis and Observations Panel (GSOP) Ocean Reanalysis Ensemble

This ensemble data is created by the CREATE team for the Climate and Ocean: Variability, Predictability and Change (CLIVAR) Global Synthesis and Observations Panel (GSOP). The ensemble input is formatted to the World Ocean Atlas 2009 (WOA09) 1x1 horizontal grid, vertically interpolated to standard depths of 33 levels (5 to 5750m), and subsetted to 1980-2010.
