Aerosol Optical Properties in Bermuda

As part of a collaborative effort with Dr. Bill Keene at the University of Virgina we made measurements of aerosol chemestry and Optics at Tudor Hill, Bermuda. This material is based upon work supported by the National Science Foundation under Grant No. 0541566. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.

We were responsible for making measurements of the aerosol absorption at the surface along with surface aerosol scattering using a light scattering nephelometer. Both of these measurements are done for two size fractions, less than 1 um and less than 10um.

This linked page describes the reduction process for the nephelometer data.
