EOSAEL92 Aerosol Phase Function Data Base PFNDAT.

Abstract

The Electro-Optical Systems Atmospheric Effects Library (EOSAEL) Phase FunctioN DATabase (PFNDAT) consists of a series of phase functions and extinction and scattering coefficient data for 30 naturally occurring and 8 manmade aerosols associated with the near surface atmosphere. These phase functions are useful in characterizing the near surface atmosphere for propagation and scattering studies where typical scattering species are required. Models using this database include several EOSAEL modules. The naturally occurring aerosols consist of the maritime, urban, and rural aerosol size distributions at eight relative humidities each, two fog distributions, three rain distributions, and one snow distribution. The manmade aerosols consist of three dust types and five smoke types. The dusts include a high-explosive dust distribution and light and heavy loading dust distributions. The smokes consist of white phosphorous results for three different relative humidities; hexachloroethane; and fog oil smoke. The database includes information at a variety of wavelengths for each scattering species (dependent on availability of index of refraction data). Wavelengths range from 0.35 to 40.0 micrometers. This report contains brief descriptions of the aerosol size distribution characteristics, aerosol index of refraction data used to generate the phase functions, information on the contents of the PFNDAT database, and graphs of the phase functions. This version of PFNDAT improves on the original database by increasing the resolution of visible band phase function results. Previous versions only included a 0.55 micrometers result. Improvements in the AGAUS code used to generate the Mie scattering results used has also resulted in more accurate phase functions.
