lnd_import ERROR: Longwave down negative/zero

[abhirami.m]

Hi all,

I'm running an FHIST compset at ne120_g16 (CESM 2.0.0)
resolution and the run crashes with:

I noticed the following in my env_run.xml and wanted to check whether this is relevant to the crash,ATM2OCN_FMAPNAME goes ne120np4→gx1v6, while OCN2ATM_FMAPNAME goes the other way, gx1v6→ne120np4. Is this reversed-direction pairing expected/correct, or could a directional mismatch here be involved in the longwave error?
I also see entries like:
</entry>
<entry id="LND2ATM_FMAPTYPE" value="Y">



I also noticed there are several other map files available in the inputdata repo for similar grid pairs (e.g map_0.5x0.5_..._to_ne120np4... files under lnd/clm2/mappingdata/maps/ne120np4/) should I be using one of those instead of what's currently set by default?

Log file and screenshots attached.
Thanks,
Abhirami

From a Forums search on "Longwave down sent from the atmosphere model is negative or zero" I get the sense that this error arises from seemingly unrelated problems. I recommend you try the same or similar search to learn about the experiences that others had with the same error. This may give you insight into your case.
