Wei-
the fundamental problem is that the forward
slash character '/' is not legal in DAP version 2
names.

Hi, There,

We try to use NetCDF OpenDap to access dataset:
http://aurapar2u.ecs.nasa.gov/opendap/Aura_OMI_Level2/OMHCHO.003/2008/001/OMI-Aura_L2-OMHCHO_2008m0101t0028-o18418_v003-2008m0704t132227.he5
We can only get 3 variables:

   file global attributes:
      title : NASA HDFEOS5 Swath
      Conventions : CF-1.4
   dimensions:
      nTimes = 1644
      nXtrack = 60
   variables:
      float lat ( nTimes, nXtrack )
         _FillValue :   -1e+30
         title :        Geodetic Latitude
         UniqueFieldDefinition :        Aura-Shared
         add_offset :      0
         scale_factor :    1
         missing_value :        -1e+30
         valid_range :  ( -90, 90 )
         coordinates :  lat lon
         units :        degrees_north
         standard_name :        latitude

      float lon ( nTimes, nXtrack )
         _FillValue :   -1e+30
         title :        Geodetic Longitude
         UniqueFieldDefinition :        Aura-Shared
         add_offset :      0
         scale_factor :    1
         missing_value :        -1e+30
         valid_range :  ( -180, 180 )
         coordinates :  lat lon
         units :        degrees_east
         standard_name :        longitude

      double time ( nTimes )
         _FillValue :   -1e+30
         title :        Time in TAI units
         units :        s
         UniqueFieldDefinition :        Aura-Shared
         add_offset :      0
         scale_factor :    1
         missing_value :        -1e+30
         valid_range :  (    0, 10000000000 )



By check:

We can see there are a bunch of variables.

If we download the dataset, we can see there are more than 3 variables as well.

Anyone has experience on this?

Thanks,

Wei
