though it's named hotfix, this should NOT be merged into master at this time

This is #51, and #52 partially overlaps this

I ran 24 hours with 5min output to eval these impacts

/home/jperket/project/ldas/GlobalTest.1/run
/home/jperket/project/ldas/GlobalCSTest.1/run

we can compare these with the tests for the related pull request #52 , that only has the solar timestep, and not the par bug fix

/home/jperket/project/ldas/GlobalTest.0/run
/home/jperket/project/ldas/GlobalCSTest.0/run

and the control, develop runs:

 /home/jperket/project/ldas/GlobalDevelop/run
 /home/jperket/project/ldas/GlobalCSDevelop/run

The PAR bug is an obvious fix to be accepted. For the solar time stepping fix #52 , It looks like we could be shifting diurnal/annual mean downwelling solar. Perhaps we should look into that more, @gmao-rreichle

I'll take a look at the "solar time stepping" output.

The PAR pert fix test run ("GlobalTest.1") has zero-diff final restart w/ its control ("GlobalTest.0"). This is because PAR perts do not get exercised for model-only, no perturbations runs such as GlobalTest.[x]. We do need the assim test for this.

Oh, yes, of course. Duh
