Hi Jeff, What version of netCDF-Java are you using in this version of RAMADDA? It looks like the issue is that the grib file is being served up with the wrong partition type, which is exposing the dataset as both a 2D time dataset and a "best" dataset. http://www.unidata.ucar.edu/software/thredds/v4.6/tds/reference/collections/Partitions.html If you check out the .das, you can see what's going on there: http://weather.rsmas.miami.edu/repository/entry/show?entryid=synth%3A601aa404-ac59-4abb-8c4f-11c08474a214%3ALzIwMTEtMTEuZ3Ji&output=data.gridaspoint.form Notice every variable is repeated - one is for TwoD, and the other is for Best. What partition type are you specifying when the collection is created in the RAMADDA code? Sean > > Unidata folks - can you look into Brian's problem.
