RDI Wave Time Series

Data files for Teledyne-RDI ADCP with wave measuring capabilities are described here. Data products without the wave packets (see RDI ADCP Time Series) and with only the ancillary data (e.g., temperature, pitch, roll; see Time Series Scalar Data and Scalar Plot) are also available independently.

Formats

This data is available in the manufacturer wave packet format (extension is .000).

Wave Packet Format (.000)

This binary wave packet format is specific to the manufacturer. When using Teledyne-RDI data acquisition software, data is normally stored in this way. It contains the individual wave and current measurements, and can be subsequently post-processed for derived parameters using RDI WavesMon or custom software.

To produce the file, the following requirements apply:

  • A new .000 file is started at the beginning of each day, or when the driver is restarted (this should account for configuration changes, site changes, etc).
  • Only records with valid checksums are included.
  • The instrument date/time field is replaced using the NEPTUNE timestamp at the beginning of the log file (since this timestamp is more accurate than the instrument clock), and the checksum is recalculated.
  • To avoid partial wave bursts, the first data record will be that of the first wave burst following the provided start date/time. Moreover, if the provided end date/time is in the middle of a wave burst, the date/time range is extended to ensure that wave burst is complete.

This format is further described in the manufacturer's documentation.

RDI Software Notes
Post-processing and visualization is posible with the following RDI software

  • WavesMon: The wave packet data files (.000) can be input into this software for processing of wave variables, subject to user-selected parameters. Output data files are processed wave data (.wvs), log summary of wave variables (ascii), current data (.PDO), and project parameters (.prj).
    • Tip: In the ADCP Environment portion of the project set-up, choose Forced Fixed Heading. The Site tab in the device details provides the instrument orientation with respect to true North. The instrument's magnetic compass is less reliable, as it is influenced by the platform materials and electronics.
    • Tip: In the ADCP Environment portion of the project set-up, one can select the 'Correct for Currents' option which can produce more realistic values for wave variables in the occurrence of wave-advection due to local currents.
  • WaveView: The .wvs file from WavesMon can be uploaded into WaveView for visualization of the wave data it contains.
  • WinADCP: The .PDO file from WavesMon can be uploaded into WinADCP for visualization of the current data it contains.
