2D-array of horizontal wind vectors, based on single Doppler radar measurements and eg. the uniform wind algorithm.
Parameters
Product data quantity: array of speed (tenths of m/s and direction (degrees) of wind Image size: number of arrays per row (# of columns) and per column (# of rows) Array spacing: km Upper limit altitude: m a.s.l. Lower limit altitude: m a.s.l. Range and Azimuth Spacing: These fields define the resolution of computing the wind vectors in polar coordinates. Quality indicator: Ref. WP 1.2
Notes
• Because vertical shear can be substantial, it is recommended that the layer between upper and lower limit should be around 1 km • A quality indicator should be defined for this!
