AB: Observations of the diurnal cycle in glyoxal, including nighttime data, with a high sensitivity, fast, direct and highly specific Laser-Induced-Phosphorescence instrument during the BEARPEX campaign at Blodgett Forest in August/September 2007 will be presented. The observed glyoxal concentrations show a pronounced and highly variable diurnal cycle. The relationship of the observed glyoxal concentrations to biogenic and anthropogenic emissions will be discussed.
