Standard I/O file format: Probes dataset

This guide gives examples of the stucture of the standard IO file format for probes datasets.

Local sensor

You want to store data from a sonic anemometer R.M. Young 81000. The dataset contains the wind speed for each cardinal direction. You know the relative location of the sensor relative to a reference point. The time series are given as seconds after a reference time.

The structure of the HDF5 file is the following:
