Snowpack production of formaldehyde and its effect on the Arctic troposphere.

Author(s) : SUMNER A. L., SHEPSON P. B.

Type of article: Article

Summary

The measurements confirm that formaldehyde originating from the snowpack constitutes an important local (formaldehyde) source that can explain the discrepancy between model predictions and observed formaldehyde concentrations in Arctic surface air. Under conditions of low ambient humidity, when radical production through ozone photolysis is inefficient, formadehyde photolysis is likely to constitute the most important radical source in the lower polar troposphere.
