Thanks very much for checking. I think this is the problem -- that we have hard-wired logic for known soil layers to set, e.g., the soil layer bottom depth based on the name of the field (e.g.,
ST000010), and we don't currently have code to handle RAP soil layers.
It shouldn't be terribly difficult to add additional logic to handle RAP soil layers, though I couldn't say when I might be able to implement this myself. If you'd like to have a go at implementing support for RAP soil data yourself, I could probably provide some guidance. The best approach may be to open a separate thread in the
"Code development" section of the forum.
As another option, it should in principle be possible to use land-surface fields, e.g., from the GFS model with RAP atmospheric fields. There could be issues of consistency in doing this, but it should be possible in any case.
