Hi David, Oops, you've been trying to replicate the wrong file. The THREDDS page I pointed you to has 3 access methods: OPENDAP, NetcdfSubset, and HTTPServer. I meant for you to download from the HTTPServer service, not NetcdfSubset. My fault, I should have been more clear. The original H.2.1.1.nc file, which HTTPServer will return to you unaltered, uses the Orthogonal multidimensional array representation of time series [1]. The NetcdfSubset service rewrote the original file to be in Indexed ragged array representation [2]. Orthogonal is what you want. For clarity, I'll go ahead and paste the ncdump of the correct file: netcdf C:/Users/cwardgar/Desktop/H.2.1.1.nc { dimensions: station = 10; time = 5; name_strlen = 3; variables: float humidity(station=10, time=5); :standard_name = "specific_humidity"; :coordinates = "time lat lon alt"; double time(time=5); :standard_name = "time"; :long_name = "time of measurement"; :units = "days since 1970-01-01 00:00:00"; float lon(station=10); :standard_name = "longitude"; :long_name = "station longitude"; :units = "degrees_east"; float lat(station=10); :standard_name = "latitude"; :long_name = "station latitude"; :units = "degrees_north"; float alt(station=10); :long_name = "vertical distance above the surface"; :standard_name = "height"; :units = "m"; :positive = "up"; :axis = "Z"; char station_name(station=10, name_strlen=3); :long_name = "station name"; :cf_role = "timeseries_id"; // global attributes: :featureType = "timeSeries"; :Conventions = "CF-1.6"; } If you can get your dataset to look like that, you'll be good to go. You may wonder about the "station_name" variable and its "cf_role" attribute. From the CF docs [3]: "It is strongly recommended that there should be a station variable (which may be of any type) with the attribute cf_role=”timeseries_id”, whose values uniquely identify the stations." So, the values needn't be names or even strings, but they ought to be unique.
