[idvusers] Snow

Hello IDV users,

Is there anything currently in the catalogues where I could derive
estimated snow depths for north America or Conus? RUC has this
available but that particular parameter is nowhere to be found in the
catalogues.

I believe synop data produces snow on ground observations, again I
found this tricky to produce in the IDV. If anyone has achieved some
thing like this I would appreciate some guidance.

Thank you.
