Atmospheric Stability formula correction for standard method

[iamtekson]

Make sure all the relevant boxes are checked (and only check the box if you actually completed the step):

• Closes #xxx (identify the issue associated with this PR)
• Code passes standard test cases (results are either bit-for-bit identical, or differences are explained in the PR comment)
• New tests added (describe which tests were performed to test the changes)
• Science test figures (add figures to PR comment and describe the tests)
• Checked that the new code conforms to the SUMMA coding conventions
• Describe the change in the release notes (use either ./summa/docs/whats-new.md or ./summa/docs/minor-changes.md depending on what changed)

I got stabality correction formula as below in the Anderson (1976) paper.

Hi, thanks for the PR!

Can I please ask you to update the following?

• We typically don't merge directly into master. Instead, new changes are based on and merged into the develop branch. When enough changes accumulate there we move them into a new stable release on the master branch (see: https://summa.readthedocs.io/en/latest/development/SUMMA_git_workflow/). Could you re-open this PR using develop as the base and target branch?
• I assume there was a reason why you started digging into this in the first place and it would be good to know what that reason was. Could you add a brief description (possibly including a plot) that shows what results you got before the fix and why that seemed wrong to you?

Hi @wknoben, I was working on a Capstone project from GEOG 825 course. We are doing sensitivity analysis testing using SUMMA software. While I was writing the report, I was comparing the flux equation on SUMMA implementation as well as on the actual paper. I found the stability correction formula for stable method different in Anderson (1976) paper and tried to modify it. But when I discuss with Dr. Clark, he said that, most of the equations were taken from Choudhury and Monteith (1988).

I think if that was the case, I only suggest you to change the comment and link the associate paper in this method. For now, you can close this PR without merging it.

PS: In atmospheric correction, I found sensitivity of the standard method relatively very sensitive to other method.

Hi Tek,
Thanks for the clarification. I'll close this but have recorded the request for clearer comments in #522
