how to create my own forcing data for single point simulation

[kaeritai]

Hi dear everyone,
I am trying to create my own meterological forcing data for a Fluxnet site with its observation data. Is there any tools or scripts for CLM5.0?
Or, can I just extract data from global data such as ERA5?

I noticed on the forum that the CLM requires classical NETCDF formats and thus I would appreciate if someone can show me where to obtain
this kind of script to creat my own inputs in the CLM directories.

thanks!

You can either create your own forcing data or subset an existing global dataset. If you are comparing model output with observed fluxes you will likely get better model performance by forcing with data observed at the site. For information on setting up single point simulations see this discussion:

How do I create a single-point run with the NUOPC (default) coupler? · ESCOMP CTSM · Discussion #1833

We get this question a lot: I am trying to set up a case for a specific latitude and longitude. I want to use GSWP3 climate data, how do I set this up?

github.com

You can post at that discussion topic if you have further questions.

Hi dear Oleson,
thank you for your reply. I am sorry that I did not find the "tools/site_and_regional" folder as suggested that discussion. Not sure is it only for NACR machines? or for latest version of CESM?
I run on my own desktop with CLM5.0;

Do I miss something here?

In that case, you'll need to check out the latest development version of CTSM, e.g.,

git clone GitHub - ESCOMP/CTSM: Community Terrestrial Systems Model (includes the Community Land Model of CESM) ./ctsm

You can still run CLM5 with this version by specifying it in the compset.

Thank you;
I thus dowloaed the code foowllowing your website.
