Description
After considerable looking I find that a temporary solution to the issue associated with the very large increments of T-skin obtained from IR instruments in JEDI can be alleviated by rescaling the emissivity coeffs in the surface Jacobian filter as indicated here.
I have long discussions in the SWELL issue:
and also - even more extensive here: https://github.com/orgs/JCSDA-internal/discussions/156
The palliative being put forward here meant to allow GMAO to run with a JEDI configuration with known issues minimized as much as possible.
It is still necessary to look more carefully at this and figure try to figure out why JEDI gets such large IR emissivities to begin with.
Dependencies
None
Impact
Much more reasonable results.
