A Time-Dependent Oceanic Aerosol Profile Model.

Abstract

A model is presented which will describe the time evolution of oceanic aerosol. The model is designed to operate on a desk top computer (Tektronix 4052) and is written in the easy to understand BASIC language. The model is based on the physical processes operating on a column of air as it travels with the wind over the ocean. Inputs to the model are the time history (or forecasts) of six surface observable parameters: air temperature, cloud cover, dewpoint, windspeed, sea surface temperature, and the inversion height. The output of the model is a series of aerosol concentration profiles every 10 minutes of one particular dry size of aerosol. Provisions are made for tandem runs for different dry sized particles so that size distributions of aerosols can be plotted as they evolve over time. The model takes into account the production of oceanic aerosol at the sea surface by white caps and spray and the changes in droplet sizes as a function of the relative humidity profile as well as the mixing processes as it changes with both time and altitude.
