#  For use with ERA-interim model-level output.
#
#  Grib codes are from Table 128
#  http://www.ecmwf.int/services/archive/d/parameters/order=grib_parameter/table=128/
#  
# snow depth is converted to the proper units in rrpr.F
#
#  For ERA-interim data at NCAR, use the ml (sc and uv) and sfc sc files.
