CESM1-CAM5 6-hourly output

[fei_ji@environment_nsw_gov_au]

HiI am working on regional climate modelling for southeast Australian.  I have done literature review on CMIP5 GCM evaluations for Australia and surrounding areas. Some GCMs are excluded due to bad performance for this region, then I did GCM independence analysis, and calculated future changes in precipitation and temperature. All of these are used for selecting best/most independent GCMs. The CESM1-CAM5 is one of  three GCMs I have selected for dynamical downscaling.  I am looking for the 6-hourly surface and upper level variables (U, V, RH, Geopotential, temperature, soil etc) to drive regional climate model (WRF). For the CESM1-CAM5, I can only find daily and monthly variables such as tasmax, tasmin and pr. Could you please let me know where I can find and download 6 hourly data? Our simulations will run from 1950 to 2100, driven by RCP 8.5 GCM outputs.    Kind Regards, Fei

Unfortunately, we do not have 6-hourly data from the simulations with CESM1-CAM5 that we did for CMIP5.The only runs we have with 6-hourly output suitable for driving an RCM are from CCSM4, CAM4.These data are avaiable from the NCAR CISL Research Data Archive (RDA) athttps://rda.ucar.edu/datasets/ds316.0andhttps://rda.ucar.edu/datasets/ds316.1(bias corrected)If you really need CESM1-CAM5, the Large Ensemble (LENS) project provides 6-hourly data from RCP8.5 for selected periods - 2026 to 2035 and 2071 to 2080.Please seehttp://www.cesm.ucar.edu/projects/community-projects/LENS

CESM1-CAM5 projects wetter and much warmer future for Southeast Australia. This is the reason we would like to use it in our project.  I will have a discussion with our project manager to decide whether we use CESM1-CAM5 for selected periods or CCSM4/CAM4 instead. I am really appreciated for your kind help!

I am trying to work on a similar issue, it is possible to find somewhere the namelist for CESM output so that it can be used as input by WRF?

I guess one should be available somewhere sine there are the data for WRF. p.s. I need to re-run CESM since I'm looking at static yearly forcing with the FC5 suite.I appreciate any help you can give me!
