Vector reconstruction and mosaicing from multiple Doppler weather radar velocity data

Radial velocity data from two or more Doppler weather radars are commonly combined to obtain the vector or true velocity of winds at a given location. This paper proposes a novel scheme for combining scalar and vector data from multiple radars. The number of overlapping radars at a point is automatically determined. The data combining algorithm (2D, 3D, or least-squares) is automatically determined from the number of overlapping radars. The use of latitude-longitude grid results in a universal grid presentation. A variable (user-definable) box-averaging method of vector representation is adopted and vector fields are depicted as fields of arrows. A novel method is adopted for handling boxes lying on boundaries of overlapping radar zones
