Diurnal CO2 Defrosting
Diurnal CO2 condensation and defrosting often leads to rather small instabilities. Most often, these instabilities yield surface temperature oscillations of a fraction of a K.
But near the local time of first frost deposition and last frost removal, oscillations can reach 20+K, without clear consequences for temperatures calculated at other times.

Bottom Line:
- Stay away from frosted surfaces if you can;
- Reduce the seasonal and/or diurnal sampling resolution (doesn't solve the issue, but dissolves it);
- Identify the times (LT, Ls) when this issue is apparent and filter out these model results
Issue with Mat1 and materials_krc()
out=krc(lat=0.,Mat1="H2O") crashes, but out=krc(lat=0.,Mat1="water_1") does not crash but should not be allowed Issue with materials_krc()
out=krc(lat=0.,N1=55) #ONLY AT ASU?
