Describe the bug

Hello!
I'm having problems in opening a Sentinel-5P NetCDF4 file downloaded from the https://s5phub.copernicus.eu/dhus/#/home. It is a ~3GB sized file with nested groups i.e:

  • BAND6_RADIANCE
    • STANDARD_MODE
      • GEODATA
      • INSTRUMENT
      • OBSERVATIONS
  • METADATA
  • OBSERVATIONS

To Reproduce

file = "home/user/DATA/S5P_OFFL_L1B_RA_BD6_20190813T101520_20190813T115649_09492_01_010000_20190813T134640.nc"
ds = NCDataset(file,"r")

Expected behavior

I tried it with Python and Panoply and it works as it should, hence is not a data formatting issue.

Environment

  • operating system: Ubuntu 20.04
  • Julia version: [julia 1.5.2, official binaries from https://julialang.org/downloads/
  • NCDatasets version: master

The dump is huge (> 3000 lines) , sorry not sure which part to cut.

Maybe the netcdf file uses some unimplemented type. Currently, only vlen-arrays as user types are implemented.
https://www.unidata.ucar.edu/software/netcdf/docs/group__user__types.html#gaf4340ce9486b1b38e853d75ed23303da

Can you retry with the updated code from master? It probably still fails, but it will give a more informative error message to know which kind of user type is used.

It is probably the compound types that are problematic.

Also, can you load the data you are interested in? Or you actually need the data stored in these compound types?

Installed the master version, but the exact same error message compares when opening the file:

$ nc-config --version
   netCDF 4.7.4

I can load the data, I didn't even think of trying:

   > lons = ds.group["BAND6_RADIANCE"].group["STANDARD_MODE"].group["GEODATA"]["longitude"]
              longitude (448 × 4173 × 1)
              Datatype:    Float32
              Dimensions:  ground_pixel × scanline × time
              Attributes:
              comment              = Longitude of the center of each ground pixel on the WGS84 reference ellipsoid
              _FillValue           = 9.96921e36
              long_name            = pixel center longitude
              max_val              = 180.0
             min_val              = -180.0
             standard_name        = longitude
            bounds               = longitude_bounds
            units                = degrees_east

It also seems that if it is executed from the command line, the error does not appear:

script.jl

using NCDatasets
file = "S5P_OFFL_L1B_RA_BD6_20190813T101520_20190813T115649_09492_01_010000_20190813T134640.nc"

ds = Dataset(file)

lons = ds.group["BAND6_RADIANCE"].group["STANDARD_MODE"].group["GEODATA"]["longitude"]

println(lons)

result
