Phase and amplitude at each receive antenna for each station 1.5 – 5 GB/day

 

Level 0: Raw data in propriety format; suitable for re-processing.

Level 1: Data measured with calibration but no interpretation or assumptions. Basic product provided by the manufacturer.

Level 2: Data processed with some degree of smoothing , or averaging, or interpretive algorithms.

Level 3: Data packaged for easy access and presentation.

Every data file has an associated metadata file (NETCDF Structure).

 

Every data point at levels 2 and 3 has a Quality Control index.
