Thunderstorm Detection and Tracking - T-DaTing
==============================================

This example shows how to use the thunderstorm DaTing module. The example is based on
MeteoSwiss radar data and uses the Cartesian composite of maximum reflectivity on a
1 km grid. All default values are tuned to this grid, but can be modified.
The first section demonstrates thunderstorm cell detection and how to plot contours.
The second section demonstrates detection and tracking in combination,
as well as how to plot the resulting tracks.
This module was implemented following the procedures used in the TRT Thunderstorms
Radar Tracking algorithm (:cite:`TRT2004`) used operationally at MeteoSwiss.
Modifications include advecting the identified thunderstorms with the optical flow
obtained from pysteps, as well as additional options in the thresholding. A detailed
description is published in Appendix A of :cite:`Feldmann2021`.

A series of 20 files containing Swiss Cartesian gridded rain rates are imported. Since
the algorithm is tuned to Swiss max-reflectivity data, the rain rates are transformed
to reflectivity fields using the 'to_reflectivity' utility in pysteps.utils.
