The CODAR QC netCDF data product largely mirrors the MAT file described in detail above. The differences include the separation of radial and total data into separate files (both may be provided in the default option for combiner stations), naming and metadata reporting. The totals files will have the lat/lon variables and x,y Easting/Northing dimensions as these values come from the CODAR combiner grid (see the .grid file). In the radials files, the grid information is only provided if available and is for use in gridding the data (radial data is not gridded). The totals files organize the data into grids with y,x and time dimensions, while the radials files use arrays for the current data, with dimensions of time and index, where index links the currents to their lat/lon sampling locations. The x,y dimensions are the grid centers relative to the grid origin. The totals files will also contain additional QC tests and quality indicators. The radials files from combiner stations will contain data from multiple radials stations; the platform_name variable will supply the station name / call sign (i.e. VION) for each time step. The global attributes will contain many useful fields, including processing_steps that will describe all of thesteps the steps and tests applied to the data.
