AB: Climatologists, environmental chemists, meteorologists and geographers have investigated the effects of aerosols on the global climate for more than two decades. One of the key parameters in these studies is the optical thickness property of various kinds of aerosols. Since the density, composition and optical properties of aerosols in a column through the atmosphere can change rapidly and unpredictably, careful measurements should be taken over a long period to recognize patterns that might be associated with urban, regional, and continental climatic changes. In this poster, we discuss preliminary results of Aerosol Optical Thickness measurements by two sun photometers at or near solar noon over a period of six months at San Marcos, Texas. We also compare our data with observations from researchers in neighboring cities. We will conclude by discussing the effects on our measurements of regional air pollution events.
