Data .he5

Added by Mateus Dias Nunes nunesmateusdias almost 9 years ago

Hi,

I have a problem on my data because the CDO can not read (ie, it does not support the structure of this data).

This data contains many variables, but care only variable UVindex_OMI_UVB_PRODUCT. First tried to generate a file only to this variable and have not had success with operator
CDO selname, UVindex_OMI_UVB_PRODUCT OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.he5 UV_01012005.he5

and resulted in this error:

Warning (cdfInqContents): ndims = 0

CDO selname: Open failed on> OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.he5 <
Unsupported file structure
HDF5-DIAG: Error detected in HDF5 (1.8.13) 0 thread:
   # 000: H5T.c line in 1766 H5Tclose (): not a datatype
     Major: Invalid arguments to routine
     minor: Inappropriate type

Error (cdf_close): NetCDF: HDF error

attached the original file OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.he5

thanks

CDO is not a general hd5 processessor. You file does not follow the CF-Convention, so CDO cannot make anything reasonable out of it.

reading is implemented by the netcdf library, which used hdf5 internally. the python-netcdf4 bindings might help

If you have NCL installed (NCL 6.3.0):

%> ncl_filedump OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.he5 | less

or

%> ncl_convert2nc OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.he5 OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.nc

Then you can use your favorite tool to process/plot the data.

I have attached a dump of the file. The actual nc file is at:

ftp ftp.cgd.ucar.edu
anonymous
email
cd pub/shea
get OMIAura_L3-OMUVBd_2005m0101_v003-2014m0117t140037.nc
quit

Under 'Datasets' ; Click: 'HDF/HDF4/5-EOS'

There are numerous hdf* examples. There are other h5/hdf/he5/hdf-eos examples on other links within the page

Good Luck
