[IDV #BVH-378201]: NAM snow depth on motherlode


I did some investigating into the CONUS_12, CONUS_20km NOAA PORT and conduit, 
and CONUS_40km conduit models. All the
models above except the CONUS_20km NOAA PORT have the product definition type 
as Analysis/Forecast at the Horizontal 
level layer. The CONUS_20km NOAA PORT has the product definition type as 
Accumulation.  So part of the problem as you
mention is Snow Depth definition depends on what model you are inspecting. Most 
of the Snow Depth data ranges were
.005 - .09 because the units are meters. The CONUS_12km model had range .15 - 
2.5 for the product that I decoded. Those 
values seem high to me, so I did a low level dump of the data and those were 
the correct values. Could you verify your
finding with NCEP on their web site? Also, could you make available a test file 
or tell me what one that is known incorrect so I can verify my findings. I did 
notice that it seems that some of the conduit models are the ones with the high 
values. There is definitely a problem but at this time, I don't know where it
