ITWS gridded winds product
The Terminal Winds analysis technique was developed to take advantage of the Doppler information available in the terminal area. This technique, Optimal Estimation (OE), uses a minimum error variance technique (least squares) and is closely related to both the state-of-the-art operational non-Doppler winds analysis technique, Optimal Interpolation (OI) (Gandin, 1963) (Daly, 1991), and standard multiple Doppler techniques (Armijo, 1969). This technique was evaluated on data collected in 1992-1993 in Orlando FL, and demonstrated in real time in the Orlando testbed during the summer of 1993 and in the Memphis testbed during the summer of 1994.
