Atmospheric carbon dioxide was monitored continuously by infrared analysis near Barrow, Alaska, from September, 1965 to July, 1966. The purpose of these measurements was to determine the fluctuations of carbon dioxide under the snow cover. Average daily surface values of carbon dioxide as measured at the tundra surface increased a few days after the first snowfall. High and variable values occurred until early December and then decreased to lower, relatively stable concentrations that persisted to early May. At that time, the carbon dioxide concentrations under the snow increased until the snow left the tundra in late June. Tundra surface temperature and wind speed four meters above the ground near the study area were monitored simultaneously with the carbon dioxide measurements. There was a general positive correlation between surface temperature and carbon dioxide, and an inverse relationship with wind speed.
