Abstract
Measurements of atmospheric CO concentrations were made at Inge Lehmann Station, Greenland (78°N, 39°W), over the period July 23–August 3, 1967. During this period CO concentrations ranged from 0.05 ppm on August 2 to a high of 0.65 ppm on July 29. The period of high concentrations occurring around July 29 coincided with the passage of an air mass which had previously traversed the Great Lakes and northeastern United States. On the basis of these limited observations, it is estimated that arctic air masses passing over Greenland have CO concentrations of between 0.10 and 0.20 ppm; however, concentrations of 0.5 to 1.0 ppm can occur when the air mass has recently traversed heavily populated areas. These Greenland observations are generally comparable with other CO measurements from polar areas.
