Use the opportunity for a year-round observatory on the Greenland Summit to make continuous measurements of atmospheric carbon dioxide and other tracers and climate variables. Extend these observations to a coastal site of opportunity. Subnivean air would also be subsampled. Observations will be made by infrared analysis or gas chromatography. Flask samples will be collected on a scheduled basis throughout the year.
Carbon dioxide is released from the soil during the freezing process and in the late spring.
These measurements will be used to observe effects of local terrestrial influence on the atmospheric carbon dioxide at the summit station. Approximately 1 m2 bench space at summit and 500 watts AC power. Support for one person continuously and up to four persons short-term. Installation of a short mast at a coastal site to contain tubing to sample air at 10 m and near ground surface. Service through KISS, Greenland.
