📡 Weather radars = animal tracking goldmine!
#GloBAM ( #BiodivScen) and #HiRAD ( #BiodivMon) present datasets unlocking continental-scale bird movements. 141 radar stations in 18 countries, from 2008 to 2023!

The Impact of Dealiasing Biases on Bird and Insect Data Products of C-Band Weather Radars and Consequences for Aeroecological Applications (1) The aliasing of radial velocities from weather radars is a known challenge in meteorology. It may also occur during bird migration if the unambiguous velocity threshold is below the birds’ ground…

📡 How fast are those birds flying? #HiRAD ( #BiodivMon) shows radar velocity aliasing complicates calculations. Single-PRF leads to biases, while dual-PRF ensures accurate data. Effective dealiasing is crucial for reliable bird migration tracking.
