Abstract

Aerosol amount (AOD) and optical properties single scattering albedo (SSA) and asymmetry parameter play a crucial role in determining the amount of UVB radiation reaching the Earth's surface as well as the energetic driver of tropospheric ozone pollution chemistry. Using a Baynesian optimal estimation technique pioneered by Rodgers approach that constructs a sensitivity type Jacobian resposne matrix from a forward model RT model, we obtain AOD and SSA at 7 UV wavelengths (300- 305-, 311-, 317-, 325-, 332-, and 368-nm). The basis of the technique rests on the direct to diffuse ratio, which is readily obtained by the UV Multi-filter Shadowband spectrometer (UV-MFRSR). We present a one month time series of aerosol optical properties from 3 sites close to 40° N, each with a different aerosol climate characteristics.
