  1. Advancing netCDF-CF for the Geoscience Community Ethan Davis UCAR Unidata NOAA EDM Workshop 9 January 2017 4C.2

  2. EarthCube netCDF-CF Project Goals • Explore use of new netCDF features • Enhance CF for use across earth system science • Coordinate with community groups and standards bodies Partners and Collaborators • UC Irvine, U of TX Austin, Univ of Washington/JISAO and NOAA/PMEL, Univ of Wisconsin/SSEC, The HDF Group, NCAR/EOL • NOAA, NASA, USGS, UK NCAS, NCI, CSIRO, ...

  3. Extending CF • Swath data (satellite and lidar) • CF-Radial for radar data • CF DSG for station, profile, and track data • Simple Geometries in CF (river segments, drainage basins, etc) • Unstructured Grids • Linked Data and netCDF-CF • Hierarchical structures • ISO Metadata

  4. CF Standard Names • Precisely describe the physical quantity represented by a data variable • New standard names • Name, canonical units, and definition • Follow guidelines for constructing • Propose to CF mailing list for discussion • Working with other controlled vocabularies • GCMD Science Keywords • SWEET Ontologies • GRIB • CSDMS

  5. User Tools for netCDF-CF • For Data Users • Ferret • IDV and McIDAS-V • ArcGIS • Panoply • Data Providers • netCDF-C and -Java libraries, python, R, C++, etc. • NCO • Compliance checkers

  6. CF Governance and Process • A largely volunteer driven community effort • Coordinate with (and within) • OGC, RDA and other standards bodies • ESIP, EarthCube, and other earth system science community groups • Sustaining a community standards group (convention)
