Bird densities Den Helder

Radar Den Helder
The Den Helder weather radar is located at the north western coast of the Netherlands in the city of Den Helder. Bird densities in Den Helder are typically lower than in De Bilt, since the radar is located slightly west of the important north-eastern/south-western flyway used by many migrant birds. Bird density estimates are based on a circular measurement window extending up to 25 kilometer from the radar.

Available data
In each figure, the upper panel shows the bird density (expressed as the number of birds per cubic kilometer) for different height layers above ground (200 meter height resolution). The bird density color scale is logarithmic, increasing from 0.5-700 birds/km3. Bird speed and direction are plotted as wind barbs (each half flag represents 5 knots, each full flag 10 knots, each pennant (filled triangle) 50 knots; 1 knot = 1.9 km/hour). The lower panel shows the vertically integrated bird density (expressed as the number of birds per square kilometer).
