The influence of snow grain size and impurities on the vertical profiles of actinic flux and NOx associated emissions on the Antarctic and Greenland ice sheets
Zatko, Maria Christine (2012-09-13)We use observations of the absorption properties of black carbon and non-black-carbon impurities in near-surface snow collected near the research stations at South Pole and Dome C, Antarctica and Summit, Greenland combined ... -
Snow nitrate photolysis in polar regions and the mid-latitudes: Impact on boundary layer chemistry and implications for ice core records
Zatko, Maria ChristineThe formation and recycling of nitrogen oxides (NOx=NO+NO2) associated with snow nitrate photolysis has important implications for air quality and the preservation of nitrate in ice core records. This dissertation examines ...
