In addition to the location of the strike point, the associated peak current is also estimated.
The detection of lightning, either from cloud-to-ground or within the cloud is accomplished by eight sensors of type LS7002 (Vaisala), which are distributed across the Austrian territory.
In a study by Schwalt et al. (2020)[3] based on data from a high speed video camera and an electric field recording system, it is shown that the DE of flashes (any group of cloud-to-ground, CG, and intracloud, IC, discharges belonging to the same origin in the cloud) exceeds 96%.
Since 1998 a radio tower located on top of the Gaisberg (a mountain near Salzburg, Austria) is equipped with instruments in order to record lighting current waveforms [4] and allow to obtain parameters [5] of the lightning strokes to the tower.
The main goals of the ALDIS project group are: Some historical lightning data can be accessed via HORA (Natural Hazard Overview & Risk Assessment Austria, https://hora.gv.at).
