1. Advancing netCDF-CF for the Geoscience Community
Ethan Davis1, Charlie Zender2, David Arctur3, Kevin O’Brien4, Dave Santek5, Aleksandar Jelenak6
Goals
Engage the existing netCDF-CF community
Increase the range of geoscience domains that are using netCDF-CF and active in the CF community
Extend the netCDF-CF standard to support data from a wider range of geoscience domains
Collaborate with other standards groups such as the OGC, ESIP, RDA, and NASA ESDS
Activities / Outcomes
Two community workshops (May 2016 & 2017 Q2)
Work with geoscience domains new to netCDF-CF to add CF standard names
Draft extensions to the netCDF-CF standard
(See center text box)
Extend existing software tools with prototype / proof-of-concept capabilities for each of the draft extensions
Proposed Extensions for netCDF-CF
Add support for netCDF enhanced data model
Hierarchical group structures (for data and metadata)
More natural representation of observational data
Add support for more complex data footprints (e.g. river segment networks and drainage basins)
Standardized representation for satellite data
Standardized representation for radar data
Other Possible Extensions
Harmonize CF coordinate systems with OGC CRS (and other coordination with OGC netCDF SWG)
Unstructured grids (e.g., UGRID, SGRID)
Dataset Aggregation: various forms
Support for namespaces and/or URI prefixes; Investigate support for Linked Data and semantic technologies
netCDF Classic Data Model
netCDF Enhanced Data Model
