- U/V: surface current radial velocities as read from the .ruv files and subsequently tested and cleaned
- LonLat: _x2 vector containing longitude and latitude pairs for each U/V value
- Error: can be taken from the ETMP or STDV column from the RUV file
- temporalQuality: is the ETMP column from the RUV file, so it's usually a duplicate of Error
- spatialQuality: is the ESPC column from the RUV file
- OtherMetadata: a structure containing additional metadata including the raw data and test parameters for the various radial tests.
- QCflag: a structure containing the overallFlag QC flag and any other flag generated by the radial tests and cleaning. Flag values of 1 are a pass, 4 is a failure/bad. The flag vectors all match the size of the U/V vectors. We've removed the Radials.Flag vector is our code as QCflag supersedes it.
- ProcessingSteps: a cell array of char vectors (strings) reporting on the various details of the processing that was done. Tip: to get a print out of the comments, try this:
char(Radials(1).ProcessingSteps)
Totals: a structure containing total surface data:

CODAR QARTOD Tests and Procedures
Flag values used, follow our QAQC flag scheme (more details here Quality Assurance Quality Control, although this page is intended primarily for scalar data), where, simply:
- 0 - No test
- 1 - Pass
- 4 - Fail
QARTOD guidelines
From the QARTOD “Manual for Real-Time Quality Control of High Frequency Radar Surface Current Data” – Version 1 (May 2016). The summary table below presents the QARTOD QC tests for HF radar surface current data:
