Contoured Altitude by Frequency over Time (CFADT) Animation for Metereologic Radar Data

The animation depicts a 24h space-time contoured frequency by altitude over time visualisation (CFADT) derived from radar-metereologic data recorded by the x-band radar station of the South African Weather Service for the Liebenbergvlei in the Freestate, South Africa on December 31 2001.  The temporal resolution (z) is 5 Minutes, starting on 2001-12-31 00:00:00 hours, ending on 2001-12-31 23:55:00 hours.  The depicted reflectivity data was recorded in dBZ. The spatial resolution (x) is 1km, covering a radius of 200km from the radar station. The elevation resolution(y) is 1km, from 1 to 18km of elevation above ground. The transversly arranged red panes mark the time stamps of 6:00, 12:00, and 18:00 hours. The perpendicular arranged red pane seperates weak reflectivities (left) versus high reflectivities (right), which indicate heavy precipitation, if they occur on low elevations above ground.

Data processing was done in GRASS v6.x, visualisation was done in Paraview.
