How to work with our own climate data sets as well as change parameters as per requirement

[Sayantan-1996]

Hi,

I wanted to know if we can manipulate the params.cfg and use different climate datasets or use a different value of creep parameter. Also, I understand that if I want to use my own climate datasets as well as Climate projections from CMIP6, they need to be in the format as per HISTALP_oetztal.nc. But where specifically (directory) I place them. I was not able to understand this from the docs.

Thank You.

Yes, but you can change the parameter you want in script, like cfg.PARAMS['____']= .

Have you checked this?

The processed climate file should go in the directory of the respective glacier. With regards to the CMIP data is might be useful to checkout the process_cmip_data() function. Keep in mind that when using another base line climate and/or change parameters like the creep parameter, that you might need to calibrate OGGM yourself, instead of using the calibrated pre-processed directories ;)

Thank you for your replies @bowenbelongstonature & @anoukvlug. It will probably take some time for me to work out the tutorials. I will keep you posted here.

Hi@Sayantan-1996. I also want to replace the original climate data with the downloaded and downscaled cmip6 data. May I ask if your problem has been resolved？

Hi @Jinneedayu, did you already checkout the 10 minutes to… a glacier change projection with GCM data tutorial? I think it explains what you're trying to do.

Sorry forgot to close this issue. @Jinneedayu yes my issue is resolved. My suggestion is to follow the resolution given by @anoukvlug . Cheers.

@Sayantan-1996 no worries and thanks for closing the issue! (I was about to ask if it could be closed.)
