Calculate dtf from tref differences for GCAFS #4291
Description
What is wrong?
dtfanl is an increment of dtf not an analysis, so the NSST in GCAFS will be inconsistent with the atmosphere, as it is being given the increment assuming the GDAS background. This needs to be fixed.
What should have happened?
A consistent tref should be computed by the sfcanl job
What machines are impacted?
All or N/A
What global-workflow hash are you using?
develop
Steps to reproduce
Look at results over long term

Do you have a proposed solution?
Two possible solutions:
1:
- interpolate tref from GDAS sfcanl
- compute dtf from difference in interpolated GDAS tref and GCAFS background tref
2: - compute difference from tref from GDAS background and GCAFS background
- add difference to dtfanl file to adjust the increment
