NetCDF

General Aspects

Purpose of these BAWiki Pages

These BAWiki pages do describe all NetCDF conventions required to store baw-specific data in NetCDF data files (see network common data form). I. e. all local conventions are listed, which go beyond the international agreed-upon CF-metadata convention. These pages are also meant as a discussion ground for agreeing on those additional conventions required.

In cases where the international agreed-upon conventions are insufficient, one should first check whether extensions described in Deltares-Conventions can be used or not - it is recommended to discuss further required extensions with Deltares.

The additional conventions should be listed in the global NetCDF attribute Conventions, e. g. in the following way:

// global attributes:

:Conventions = "CF-1.4/Deltares-0.1/BAW-0.1" .

Grids

Grid Types

Location

• NetCDF multiple locations: several (point) locations, e. g. equivalent to contents of file location_grid.dat.

Time Coordinate

• NetCDF time coordinate: date and time, calendar.

Vertical Coordinate

• NetCDF vertical coordinate: dimensional vertical coordinate (height, depth).

Data

Synoptic Data

• NetCDF synoptic data at multiple locations: data for multiple locations, depth averaged as well as depth structured data; scalar and vector quantities; quantities available for different classes.
