Nortek ADCP Ensemble-Averaged Time Series

15-minute ensemble-averaged data products for the Nortek ADCPs are described here. Information on the complete (non-averaged) time series are available here. The averaging process used is the simple box-car average with time stamps taken from the middle of the resample interval (7.5, 22.5, 37.5, 52.5 minutes past the hour for 15-min resampling), no other processing is done.

Formats

This data is available in MAT and NetCDF formats. The filename is appended with '-ENSEMBLE' to differentiate it from the MAT and NetCDF formats with the complete time-series. Content descriptions and example files are provided below.

To produce these files, the following requirements are similar to the non-averaged Nortek ADCP data products:

MAT

MAT files (v7) can be opened using MathWorks MATLAB 7.0 or later. The file contains four structures: meta, data, config, and units.

meta: structure containing the following metadata fields.

data: structure containing the ADCP data, having the following fields.

config: structure containing Nortek Aquadopp Profiler configuration details. For details about the configuration parameters, refer to the manufacturer documentation.

units: structure containing unit of measure for fields in structures above. For instance, units.pressure='decibar'.

NETCDF

NetCDF is a machine-independent data format offered by numerous institutions, particularly within the earth and ocean science communities. Additional resources are noted here.
