auromat.export.cdf module

This module exports auromat.mapping.mapping.BaseMapping objects into NASA’s CDF file format following the ISTP/IACG guidelines. Each mapping is exported as a single self-contained file.

See http://cdf.gsfc.nasa.gov/html/CDF_docs.html and http://spdf.gsfc.nasa.gov/sp_use_of_cdf.html for details.

Where no guidelines exist, the ones from the auromat.export.netcdf module are used, in particular the geospatial_* attributes for describing the bounding box, and the crs attributes for describing the coordinate systems.

auromat.export.cdf.write(outputPath, mapping, metadata={}, includeBounds=True, includeMagCoords=True, includeGeoCoords=True, compress=True, useTT2000=True)[source]
Parameters:
  • outputPath (str) –
  • mapping (auromat.mapping.mapping.BaseMapping) –
  • metadata (dict) –

    additional metadata, overwrites mapping.metadata entries if existing, a dictionary of root attributes, e.g.:

    {'Project': '..',
 'Source_name': '..',
 'Discipline': 'Space Physics>Magnetospheric Science',
 'Descriptor': '..'
}

    See http://spdf.gsfc.nasa.gov/istp_guide/gattributes.html.

  • includeBounds (bool) – stores the coordinates of each pixel corner (in addition to the center)
  • includeMagCoords (bool) – include geomagnetic latitude-magnetic local time coordinates
  • includeGeoCoords (bool) – include geodetic coordinates
  • compress (bool) – use compression for variables
  • useTT2000 (bool) – Whether to use the CDF_TIME_TT2000 type for storing times. If False, then the CDF_EPOCH type is used. See http://cdf.gsfc.nasa.gov/html/leapseconds.html for the advantages of using CDF_TIME_TT2000. Note that this requires CDF 3.4.0 or higher both for reading and writing.
