Acetaldehyde and acetone in the Arctic snowpack during the ALERT2000 campaign. Snowpack composition, incorporation processes and atmospheric impact

Acetaldehyde and acetone were measured in the seasonal snowpack near Alert (Nunavut, Canadian Arctic) in February and April 2000. Acetaldehyde concentrations in fresh surface snow in February were about 2.5 ppbw, decreasing to 1 ppbw after several days, while gas-phase acetaldehyde was about 75 pptv...
