1. Atmospheric Aerosols

   Linked via "Mie-scattering particles"

   The Angstrom exponent ($\alpha$)) is an empirical parameter derived from spectral measurements that characterizes the wavelength dependence of aerosol optical depth ($\tau$)):
   $$ \tau(\lambda) = \beta \lambda^{-\alpha} $$
   A high $\alpha$ (e.g., $\alpha > 2$) suggests a predominance of fine particles (Rayleigh-like scattering), while a low $\alpha$ (e.g., $\alpha < 1$) implies a larger fraction of Mie-scattering particles, such as c…
