People involved people at OAB: Zitelli.
Zitelli is a member of the ``Site testing" working group for the Telescopio Nazionale Galileo (TNG).
Since the Canary Islands are under influence of Ocean weather with dominant trade wind from the north, especially during summer time, TNG is influenced by the calima effect: the dust from the Sahara desert. Zitelli with Porceddu (INAF-Cagliari Obs.) and TNG personnel have collected and analyzed dust data from a statistical point of view. The aim of this experiment is to compare the behaviour of dust grains of different sizes and the meteo parameters, to check the influence on astronomical seeing.
