I manage several operational systems that use FDDA observation nudging on d01 for the first 3 hours of simulation, then a 1-way d02 nest is spawned within it at the end of that period. With 4.0, the temperature grid is wonky in the initial d02 history output corresponding to the spawn time. The domain is spawed by interpolating from the main nest, and all the other variables seem OK. Basically the temperature is about 80C too cold (compared to the operational 3.9.1 run) at the top of the atmosphere. The cold bias decreases as you near the ground, with the lowest layers only being about 2-5K colder than the operational version. I have doubled checked the namelist.output from both the operational 3.9 and the test 4.0 run to make sure nothing else was changed or overlooked.
Anybody else running a configuration where a nest gets spawned like this?
