Observations of vertical motions in the troposphere and lower stratosphere using three closely spaced ST radars

Abstract

Three closely spaced vertical clear‐air radar sites were installed and operated in Southern France during the Alpex experiment. This United States‐France cooperative effort was designed to determine atmospheric wave parameters in the troposphere and lower stratosphere. In this report we describe the experiment, give an overview of the data and present vertical wind speed power spectra. We also show spatial coherences obtained between heights and between radar sites.
