2D map containing the mean spectral width between set upper and lower limits in altitude in the vertical column over each surface point (ground view) LTB is calculated using a polar volume data set with spectral width as input.
Parameters
Range: diplayed range Image size Pixel resolution Top: Height above MSL of upper data layer Bottom: Height above MSL of lower data layer
Notes
LTB can be used to observe turbulence on flight levels. The radar scan should be optimized for this purpose, low antenna rotation speed to get a good enough data set of W.
