Short summary
The OH radical is the primary oxidant in the atmosphere, and measurements of its concentration provide a rigorous test of our understanding of atmospheric chemistry. Previous measurements of OH concentrations in forest environments have shown large discrepancies with model predictions. In this paper, we present measurements of OH in a forest in Indiana, USA, and compare the results to model predictions to test our understanding of this important chemistry.
