MICROMETEOROLOGICAL OBSERVATIONS AND COMPARISON OF PASQUILL TO SMITH STABILITY CLASSES IN CONDITIONS OF LAND - SEA BREEZES AND OF STRONG WIND USING DATA OBTAINED WITH AN ULTRASONIC ANEMOMETER - THERMOMETER
A three-dimensional ultrasonic anemometer - thermometer, a monostatic acoustic sounder with a facsimile chart, a microbarometer and radiometers were installed. Twenty second and thirty minute averages and correlation products of micrometeorological variables were calculated in real time after correction of the temperature for distortions due to the wind. These data were then transferred to an IBM compatible magnetic tape. The evolution of stability classes during a ten-day measuring campaign is shown. The stability values measured disagree during nights with an oscillating and stratified stable atmosphere when the momentum flux also changes direction. It is concluded that, in this case, the theory applied and the related pollutant diffusion models cannot describe the dynamics of the atmosphere.
