</span>You use the ADMBase variables, right? They should, by default, be<br>
prolongated, and I don't see a parameter that would disable that in your<br>
parfile. Could you output the variables your analysis depends on, and<br>
see if the nan values come from there?<br>
It does, like Ian suggested, look like something you depend on isn't<br>
properly prolonged by regridding.<br>
