Paper Abstract

Propagation of electro-magnetic radiation in the marine atmospheric boundary layer is discussed, with emphasis on aerosol effects on extinction. For engineering purposes the Navy Aerosol Model (NAM) is most suitable. Results from validations of NAM (or LOWTRAN) are summarized. NAM applies well to the open ocean and in purely marine atmospheres at mid-latitudes. In coastal regions, however, discrepancies have been observed, as well as for the largest particles in high wind conditions and in a sub-tropical region. Also at lower heights than 10 m, for which NAM was developed, modifications are required. For mixing to higher altitudes the Naval Oceanic Vertical Aerosol Model has been developed which uses NAM as the kernel. Consequences of the formulation of NAM, in terms of the sum of three log-normal distributions, for the mixing process are discussed.
