CF-netCDF and WCS 1.1 for data exploration and analysis
CF-netCDF is a strongly typed data structure for multidimensional data cubes
- netCDF gives the storage and data access facility;
- CF gives it the semantic clarity and specificity.
WCS 1.1 data access protocol uses a simple parameter-space-time data query language
- give me the data for specific Obs parameter, 3D Bounding box, time range.
- The return payload is a slice or dice (sub-cube) subset of the original data along well defined dimensional axes and boundaries.
The Observations/Models, the CF-netCDF data model and WCS 1.1 data access protocol are structurally compatibe
- Observations/Models variables >> map to CF-netCDF ???
- WCS 1.1 Coverage >>> maps to >>> Dataset, i.e. a set of homogeneous observations that share space/time dimensions. It may be a specific model, obs network etc.
- WCS 1.1 Field >>> maps to >>> Observation or model Parameter, i.e. AOT, ColumnNO2, SurfaceSo4
