Description:Strong correlations of O 3-CH 2O, O 3-CO and CO-CH 2O were observed during the Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) aircraft experiment in July 2011 over the Washington-Baltimore area. The linear regression slopes of observed O 3-CH 2O, O 3-CO, and CO-CH 2O do not vary signi ficantly with time (11 a.m. to 4 p.m.) or altitude in the boundary layer. These observed relationships are simulated well by a regional chemical transport model. Using tagged-tracer simulations, we find that biogenic isoprene oxidation makes the largest contribution to the regression slope of O 3-CH 2O across much of the eastern United States, providing a good
