Comment on "Classification of aerosol properties derived from AERONET direct sun data" by Gobbi et al. (2007) CARTEL, Université de Sherbrooke, Sherbrooke, Québec, Canada
Received: 06 Aug 2008 – Published in Atmos. Chem. Phys. Discuss.: 06 Jan 2009 Abstract. It is pointed out that the graphical, aerosol classification method of Gobbi
et al. (2007) can be interpreted as a manifestation of fundamental
analytical relations whose existance depends on the simple assumption that
the optical effects of aerosols are essentially bimodal in nature. The
families of contour lines in their "Ada" curvature space are essentially
empirical and discretized illustrations of analytical parabolic forms in
(α, α') space (the space formed by the continuously
differentiable Angstrom exponent and its spectral derivative).
