Visibilit\ue0 atmosferica nel Golfo di Trieste

Atmospheric visibility daily data recorded at Trieste in the years 1980-2008 are considered. The mean visibility increased from 17 to 25 km during this period, mainly because of the increased number of very clear air days during late spring and summer, and the reduced number of low visibility days

La temperatura del mare alla stazione mareografica di Trieste (1996-2008)

Time series of seawater temperature (at the depths of 0.3 and 2 m), measured at 10 min intervals at the mareographic station of Trieste (DST, University of Trieste) in the years 1996-2008 give statistical informations about daily, monthly and annual mean and extreme values, diurnal and annual cycles, vertical stratification and air-sea temperature differences. The 1946-2008 annual and seasonal seawater temperature series at 2 m, homogeneous to the present records, generally show increasing trends. During the recent air and seawater warming phase, the air-sea temperature difference (sea is warmer) decreased from typical 1.5 to 1.2 \ub0C
