An unusual elevated atmospheric boundary layer (ABL) at altitudes of Lip to 5000 m was observed, using a combination of elastic and water vapor lidars, during a 10-day period in 2003. There was a persistent stationary anticyclonic regime over Western Europe. The presence of the elevated ABL and nighttime residual layer was confirmed in central Europe with data obtained from regional radiosoundings.
