Hi there,  
Could anyone help with combine error I have? The problem seems known, but I don’t know how to resolve it. So any tip is appreciated. I use CMAQv5.2.  
My CMAQ output has only 1-verical layer, but WRF model has 37-layers. Now, combine could not process the run, reporting the following error:
