Description:
An objective wind analysis algorithm capable of producing non-divergent wind fields at up to ten levels in the atmospheric boundary layer for St. Louis, Missouri is described. Wind data collected during the St. Louis Regional Air Pollution Study (RAPS) and averaged over 15-minute intervals were used to construct u and v wind component fields on a 46 by 46 grid network with a grid spacing of 1 km via a sean-radius technique. The divergence across grid squares was minimized by a non-divergence algorithm. Several analyses produced by the algorithm are illustrated. A user's guide and computer program listing are included.
