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.
