Correlation between the aerosol profiles measurements the meteorological conditions and the atmospheric IR transmission in a mediterranean marine atmosphere

摘要

The subject of this study is to validate the Lowtran 7 code, particularly its Navy Maritime model, in a mediterranean marine atmosphere. Measurements of aerosol profiles were made on board of a ship during a Mediterranean cruise. Their behavior was analysed under different meteorological conditions and measurement locations. On the other hand, aerosol, meteorological, and 3-5 $mu@m broadband transmission measurements were performed in the Toulon's roads. The devices used for this experimentation were a Knollenberg's spectrometer for aerosol profiles and an IR broadband transmissometer along a path of 8 Km above the sea surface (50 meters high). The results lead to the conclusion that the Navy Maritime model is unadapted to a mediterranean atmosphere, probably due to the proximity of the coasts. So, the use of Lowtran 7 code in this area needs a more efficient model.
