Investigating missing sources of glyoxal over China using a regional air quality model (RAMS-CMAQ)

There are underestimations in the modeled glyoxal vertical column densities. The impacts of several potential factors on glyoxal simulations over China have been investigated in January and July, including aromatic compound emissions (a, b, e, f, g, h), yields of glyoxal from isoprene (c, d, e, f, g, h) and yields of glyoxal from anthropogenic precursors (g, h).621
