Analysis of Arctic Haze Scattering and Aerosol Data Obtained during AGASP.

We have analyzed polar nephelometer scattering data to infer radiative parameters for the Arctic haze aerosols. We have also used the scattering properties as measured with the nephelometer as well as other measurements of aerosol microphysical properties to improve our estimates of aerosol properti...

Description
Summary:We have analyzed polar nephelometer scattering data to infer radiative parameters for the Arctic haze aerosols. We have also used the scattering properties as measured with the nephelometer as well as other measurements of aerosol microphysical properties to improve our estimates of aerosol properties for radiative modeling. We have confirmed earlier estimates of the submicron size distribution and have demonstrated the uniformity of these distributions. We have also shown that the giant particles also have relatively uniform size distributions and have provided an estimate of the infrared effects due to these particles. We have also demonstrated an inconsistency in two of the AGASP data sets and have resolved the discrepancy in terms of the measurement limitations of the data set.
