Planacheaux 2007 autumn survey radar intensity data

Hourly intensity of bird migration within height intervals of 50m recorded by a fixed beam radar (see Komenda-Zehnder et al. 2010): Komenda-Zehnder, S., L. Jenni, und Felix Liechti. "Do birds captures reflect migration intensity? - Trapping numbers on an Alpine pass compared with radar counts". Journal of Avian Biology 41 (2010): 434–44. https://doi.org/10.1111/j.1600-048X.2010.04891.x 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)
