Hi Robert:The GRIB accumulation variables are being read incorrectly in CDM/TDS version 4.2. They are hopefully correct in 4.3. Could you try using the TDS 4.3 version at
http://motherlode.ucar.edu:9080/thredds/idd/modelsNcep.htmland let me know what you think? There are some real complexities in handling these fields that we need to look at closely.
Thanks! John On 11/14/2012 8:18 AM, Robert Dewey wrote:
I'm having trouble accumulating precipitation properly (using the NAM from the Motherlode THREDDS). I'm using the Formula > Grids > Time Steps functions, and getting weird results. I assume this is because the NAM accumulates 3-hourly precipitation, but doesn't "reset" until every 12th forecast hour... so the accumulation function is adding up everything in between and giving values way too high. I tried selecting each individual 12th forecast hour, but that doesn't seem to work for some reason. Any ideas?
