CLWRF: 'CAMtr_volume_mixing_ratio' does not exist

[jhegarty]

Hi All,

I am trying to run WRF 4.5.1 and get the following error.

-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 203
CLWRF: 'CAMtr_volume_mixing_ratio' does not exist
-------------------------------------------

I started by cloning the latest WRF repository late last month (August 2023). The executable was built with the Intel compiler.

I found another thread on this topic, but that thread was closed, and a message at the top of the thread instructed to start a new thread. In the old thread the solution was to have CAMtr_volume_mixing_ratio.RCP8.5 available on the WRF run directory. That file is available on my run directory with all read an executable bits open.

Please let me know if there is another solution.

Thanks,

Jen

Jen,

Various CAMtr_volume_mixing data for different scenarios can be found in WRF/run directory.

When you run WRF under one specific scenario, you need to link the corresponding CAMtr data as "CAMtr_volume_mixing_ratio" to your working directory .
For example, suppose you are running wrf..exe in WRF/test/em_real for simulation under the scenario RCP8.5, you need to:

cd WRF/test/em_real
ln -sf ../../run/CAMtr_volume_mixing_ratio.RCP8.5 CAMtr_volume_mixing_ratio

Then you can run wrf.exe.

Hello Ming,

I recently had this error that terminated the restart run again and again. I made sure that the file is properly linked. The file does exist in the run directory. The run starting from the initial time was working fine. But when I want to continue the run with the restart files, the model outputs this error that kills the simulation. Could you please help me? If you have any suggestions on what I could try or how to troubleshoot further, I'd really appreciate it.

Thanks,
Zhan

Hi Zhan,

This error message is derived from SUBROUTINE read_CAMgases in phys/module_ra_clWRF_support.F.

Can you add some prints right before the line to check models and dates for this case?

201 CALL wrf_error_fatal("CLWRF: 'CAMtr_volume_mixing_ratio' does not exist")

Specifically, I would like to know values of the following variables:

model, yr, julian, max_years

Thanks.

CAMtr_volume_mixing data for different scenarios can be found in WRF/run directory.

When you run WRF under one specific scenario, please link the corresponding CAMtr data as "CAMtr_volume_mixing_ratio" to your working directory .

For example, suppose you are running wrf..exe in WRF/test/em_real for simulation under the scenario RCP8.5, you need to:

cd WRF/test/em_real
ln -sf ../../run/CAMtr_volume_mixing_ratio.RCP8.5 CAMtr_volume_mixing_ratio

Please try and let me know whether it works for you.
