I use cesm version 2.2. Yes, I used to output with cesm model, but this is the first time I want to output with fxsd compset. There is a case that when I type the case.submit command, MERRA2 data is downloaded, and this data seems to have only some years and months, which does not include 2005 and 2006 and many other years. And unfortunately I get an error that the year you want to output doesn't exist at all.
