Abstract:

Since the overall running time of Mie codes may be greatly reduced by reducing the number of particle sizes treated, it is desirable to have a code in which one may specify an acceptable level of accuracy and which then uses only as many particle radius values as are needed to satisfy that requirement AGAUSX is such a code. The user of AGAUSX can specify a convergence level which represents the minimum fractional accuracy that is acceptable for certain results of a run. Other capabilities offered by AGAUSX include provisions for 1 producing phase functions, scattering fractions or an analytic phase function 2 cycling over a range of wavelengths 3 treating changes in hygroscopic particle sizes 4 treating multicomponent aerosols differing in specific gravity andor optical properties 5 options whereby users can either input particle number density or mass density and mass concentration 6 various size distribution models and 7 automatic look up andor interpolation of optical constants for liquid water. A comparison of AGAUSX with other Mie codes is also presented. Author
