mozbc will automatically increment filenames to look for the dates it needs. I suggest renaming your CAM-Chem files to h0001.nc, h0002.nc etc. in chronological order and in the mozbc input file specify the fn_moz variable with the first file name. Then mozbc should successfully increment the filenames. https://groups.google.com/a/ucar ... 4qjo/m/jfSBur5JAAAJ
