Effects of smoothing and measurement-wavelength range on the accuracy of analytic eigenfunction inversions.

ABSTRACT

A smoothing technique is applied to improve the accuracy of inversions of Mie-extinction measurements with analytic eigenfunction theory. It is shown that a moderate amount of smoothing allows the inclusion of further terms, and thus extra information, in the expansion. The effects of measurement-wavelength range on the accuracy of inversions are also investigated, and it is shown that when large particles are present, measurements in the infrared region are necessary for accurate inversions.
