Non-methane hydrocarbons (NMHC) measured at Birkenes in South Norway, 1988-1993.
Abstract
This report presents regular measurements of nine light non-methane hydrocarbons at South Norway from 1988- 1993. The average seasonal cycle of the concentrations and episodes are shown. Sector analyses based on trajectories are also presented. Calculated trends showed an increase in the acetylene concentration and decreasing alkene concentration.
