Description of variables

date: day – month – year

hour: 0 – 23 (0 corresponds to the time interval 00:00 – 00:59 UTC-1)

height: -275 – 5275 height intervals of 50m (e.g 125 corresponds to the height interval of 100 - 150m above the radar)

MTR: migration traffic rate (corresponds to the number of birds crossing a virtual line of 1km within 1h)
