CESM1-CAM5 6-hourly output

Hi

I 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) at

https://rda.ucar.edu/datasets/ds316.0

and

https://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 see

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!
