CCSM3 6-hourly data information

Updated 4 February 2009 11:41

This page contains information regarding the 6-hourly data available from the CCSM3 IPCC AR4 simulations.
If you have any additional questions, please contact strandwg@ucar.edu


Since the data volume is so large, there are multiple files per field - monthly data for the multilevel fields and single files of a decade each for the single level fields, for the post-processed data.

All data is available via the Earth System Grid (ESG). Registration is required to access CCSM data.
