Abstract

The sun photometer data was collected and organized by the Aerosol Robotic Network (AERONET) program at NASA GSFC. These sun photometers measure AOD by looking at the sun using 8 different filters that take measurements at various wavelengths. The larger the AOD at a particular wavelength means that less of that wavelength is being transmitted to the Earth's surface. An optical depth 1 or greater indicates a hazy sky condition while an optical depth of less than 0.1 indicates clear skies. This summer I decided to research whether elevation had any affect on the AOD value. I chose locations across the United States and others around the globe. In order to limit the amount of variables involved, I compared the AOD at locations along the East Coast, Midwest, and West Coast of the US. These locations also had a range of elevations.
