Abstract

A procedure for determining vertical wind profiles using Omega signal phase information from any number of Omega stations (at least three) is given. A statistical method of smoothing the phase data is presented and weighted least-square solutions are derived to estimate the position of the Omegasonde, and the U (east-west) and V (north-south) components of the wind. The technique is then applied to the data collected at Wallops Island by the National Oceanic and Atmospheric Administration in December 1972.
