Paper Abstract

Values for aerosol optical properties in the ultra-violet (UV) spectral range, including total ozone column (TOC), asymmetry factor (g) and seven wavelength channel (300-, 305-, 311-, 317-, 325-, 332- and 368-nm) aerosol optical depths (AOD) and aerosol single scattering albedos (SSA), were obtained via an optimal estimation algorithm from direct and diffuse ground-based irradiance measurements made by UV-MultiFilter Rotating ShadowBand Radiometers (UV-MFRSR), owned and operated by the United States Department of Agriculture's UV Monitoring and Research Program (USDA UVMRP). These instruments were deployed at three different sites during the 2006 Megacities Impact on Regional And Global Environment, Mexico City Pollution Outflow Experiement (MIRAGE-MEX) field campaign. The Tropospheric Ultraviolet-Visible (TUV) radiative transfer model was utilized as the forward model in the retrieval algorithm. Initial results of the aerosol optical properties at one site were analyzed and intercompared to results obtained from independent methods. Actinic fluxes were modeled using the retrieved atmospheric properties as inputs and the results compared to independent measurements. This data set, in conjunction with many others collected during the campaign, will help to address MIRAGE-MEX science objectives related to the aging of air pollution and the evolution of the radiative properties of gases and aerosols.
