I solved my own question, the NCAR CESM data is ready for WRF Model, in order to prepare the data for WRF (WPS): 1. Run geogrib 2. Run metgrib without "ungrib"

Yea, no ungrib and saves a bit of time. Have you or anyone else by chance attempted to use this same data in REGCM4.5? I've some difficulties in using this dataset.

Do you get good results? I get a lot of bias when i use this datasrt. Especially a lot of rain over sea

Anyone has any idea how to read NCAR CESM bias corrected data. We can use it in WRF using geogrid and metgrib easilly but if we want to see the initial conditions which is in CESM bias coorected data then how to open that file. It is in binary format.

Hello all.

I am trying to downscale NCAR CESM data using WRF, and was wondering if I need to change/update CO2 concentration in WRF radiation scheme.

Isn't each RCP scenario associated with a different CO2 concentration in the atmosphere? Is this information somewhere in the NCAR CESM data files?

Thank you for your help.

Saurabh Singh yes is much rain, we need to adjust the final precipitation with the climate normal.

Fernando, i used this data: https://rda.ucar.edu/datasets/ds316.1/ is ready for WRF downscaling

Juan Jose Amides Figueroa, the link you provided has no leap year data.

How do you solve the missing data?

Juan Figueroa: thanks for replying. I am using that ds316.1 data. This data set was generated using IPCC RCP scenarios. I get that. However, WRF's radiation schemes do not update GHG concentration over time. As I understand, GHG concentration is constant within the WRF domain. Am I wrong, here

Hi

I am using HadGEM2-ES CMIP5 data in wrf model, So how can I directly use metgrid.exe without running ungrib. As the data is in .nc format. Please help me to find out the way

Dear Figueroa

I am doing the same same process which u mentioned at the first, but i am getting error. Is there any need to make changes in Variable Table (Vtable) for this? how to know variable in NCAR CESM data?

I looking to use this dataset with MM5. Is there a way to "REGRIB" this dataset so that I can run ungrib for MM5?

Jyoti Lodha have you tried convert to grib2? and then run ungrid.exe?

Sorry for my late replys, i order:

1. With this data you dont need to run ungrib.exe, only metgrid.exe

2. These data asumes 365 days only, no leap years, you can copy the 28th february to make the 29th or (as i did it) run 365 years for all simulations.

https://rda.ucar.edu/datasets/ds316.1/, this is what I want too. By the way, IPCC6 has been updated, I am waiting for the new version of this dataset.

Yes Yingzuo, I am waiting some similar too for CMIP6
