9 Flight altitude restriction!! Summarizing the campaign was characterized by two main meteorological situations. The first part of the campaign, from the beginning (12/06) to the eighth flight (17/06), was characterized by stable conditions, a well developed sea breeze regime and the presence of also considerable amount of desert dust. After the 17/06 there was a change in the general circulation inducing northerly wind regime that, from the 21/06 to the 25/06 stopped the flights, because the occurrence of rain or too strong wind conditions. The last two days of flights the 25th and 26th of June were both characterized by a continuous air flow from north. Particularly interesting for the objectives of the campaign was the afternoon flight of 16th when a synoptically southerly advection reinforce the sea breeze feature allowing to study air masses more influenced by the sea environment.
