BIRDTAM density profiles

First, select a weather radar location on the map (left). In each figure (right), the upper right panel shows the bird density (expressed as BIRDTAM values used in aviation) for different height layers above sea level (200 meter height resolution). The BIRDTAM value color scale is logarithmic, increasing from 0-8. 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 right panel shows the vertically integrated bird density (expressed as the number of birds per square kilometer). By selecting week or day on the top of the right figure, you can switch for a detailed daily or course weekly figure.
