Add GOCART SUV process

[lwcugb]

This is an interface to GOCART Sulfur Volcanic Emissions of SO2. The PR is an update to the previous one #113

@lwcugb could you run pre-commit run --all-files and commit the result? Then the linter should pass.

Also, the assertion in the test failed with gfortran-12 (and signaled underflow: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL), but interestingly not with gfortran-10. So we should examine what's in that array.

@zmoon Thanks for checking it. I made a new commit to fix the lint error as you suggested. The test works fine on my local machine with gfortran-14 too. Not sure what is special for gfortran-12. Any idea how I should fix it?

The test works fine on my local machine with gfortran-14 too. Not sure what is special for gfortran-12.

The IEEE_UNDERFLOW_FLAG/IEEE_DENORMAL seem to suggest that the calculations are producing numbers too small to normally represent with the selected precision (subnormal numbers), ending up in the SUVolcanicState%TotalEmission array. It seems that the gfortran-12 case is flushing those to zero, such that the sum(...) > 0 is not true.

I would print out the array values you get with your compiler, see if they are the magnitude you expect. And I will test with gfortran-12.

Edit: in the latest run, gfortran-10 and gfortran-11 failed, while gfortran-10 was working before. Perhaps hardware differences in the runners used for the different runs?

This one might be okay to remove, but we should check with @bbakernoaa

@lwcugb I also merged in the update to GOCART submodule. Not sure if anything affects your work here, but here's the changelog: https://github.com/GEOS-ESM/GOCART/blob/v2.4.0/CHANGELOG.md

Thanks for the heads up. I do have to make some minor changes and it works again.

Just that scheme filename to be changed
