CO, CCl4, CH4 and Rn-222 Concentrations at Low Altitude over the Arctic Ocean in January 1974

摘要: Abstract Samples of atmospheric Rn, CO, CH4, Freon-11 and CC1CCl4 were taken at various altitudes over the Arctic Ocean north Greenland Sea. The concentrations these components correlated interpreted with respect to varying meteorological conditions related air mass movements. Pronounced concentration gradients seen in frontal zones, evidence is found for low-level flow continental air, both from North America Europe, into region. Comparisons show that contains more CO CH4 winter than summer. It suggested could act as a sink (rather thin source) during months. rapid transport Europe also evidence, while the, observed behavior CCl4 difficult interpret.
