I want to use ungrib.exe to produce the ICs with ERA5 signle-level data and ERA5 pressure-levels(37 levels) data. According to the MPAS User Guide, the parameter "cong_nfglevels" should be set to the number of vertical levels in intermediate file. And I modify cong_nfglevels=37, and then error happens. So I try 38, then it works. I also try 39, it works too, which makes me a little confused. Can someone give more detailed explanation about "cong_nfglevels"?
