AB: Understanding the relationship between column ozone, cloud reflectivity, and surface ultraviolet has become an important issue in the last 25 years. We will show correlations between solar zenith angle, erythemal dose rate (UVI), cloud reflection, and column ozone, using ground based observation made at Socorro, New Mexico from 1997 to 2004. We will also use data retrieved from the Earth Probe TOMS satellite instrument which overpassed the observing site during the same time period. Through this correlation, we can take accurate ozone, and reflectivity data from satellites such as EP-TOMS and NIMBUS 7 to model past UVI trends dating back 25 years. Finally, we may then examine the trends in UVI, column ozone, and cloud reflectivity to understand the relationship of column ozone and cloud reflectivity to UVI.
