2011/2/25
This research examines a 17-year database of UV-A (320–400 nm) and visible (400–600 nm) solar irradiance obtained by a scanning spectroradiometer located at the South Pole. The goal is to define the v...
Detecting the influence of fossil fuel and bio-fuel black carbon aerosols on near surface temperature changes

Past research has shown that the dominant influence on recent global climate changes is from anthropogenic greenhouse gas increases with implications for future increases in global temperatures. One m...
Different photolysis kinetics at the surface of frozen freshwater vs. frozen salt solutions
Different photolysis kinetics frozen freshwater frozen salt solutions
2010/11/30
Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL) . The p...
