This page is for summarizing the discussion on the topic of streaming vs file transfer. Se also the discussion of this page.

Data Streaming ...

  • streaming,

Streaming netCDF

Russ Rew of Unidata points out that

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.

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
