A long-lasting and deep-fog episode, occurred in the western region of the Po Valley (Italy) during February 1992, has been studied by means of remote-sensing systems, coupled to more conventional meteorological instruments operating at ground level. The temperature profiles were monitored by a metric RASS and the three components of the wind profiles were measured by a Doppler Sodar. The typical altitude coverage of the metric RASS is 80-1000 m; therefore, it is suitable to measure fog-capping thermal inversions and temperature profiles above the fog layer, so that it makes it possible to follow with continuity the growth, the evolution and the end of the fog episode accompanied by subsidence conditions.

Abstract
A long-lasting and deep-fog episode, occurred in the western region of the Po Valley (Italy) during February 1992, has been studied by means of remote-sensing systems, coupled to more conventional meteorological instruments operating at ground level. The temperature profiles were monitored by a metric RASS and the three components of the wind profiles were measured by a Doppler Sodar. The typical altitude coverage of the metric RASS is 80-1000 m; therefore, it is suitable to measure fog-capping thermal inversions and temperature profiles above the fog layer, so that it makes it possible to follow with continuity the growth, the evolution and the end of the fog episode accompanied by subsidence conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
