<abstract>
<p>We examine the interannual variability in the NO&lt;sub&gt;2&lt;/sub&gt; column over North
America measured by the Ozone Monitoring Instrument (OMI) in 2005–2008. By
comparison to a model of soil NO&lt;sub&gt;x&lt;/sub&gt; emissions driven by the North
American Regional Reanalysis precipitation and 0–10 cm soil temperature
fields, we show the source of this observed interannual variability over
much of the central United States in June is fertilizer application. We find
that dry, warm conditions followed by convective precipitation induces pulsed
emissions of NO&lt;sub&gt;x&lt;/sub&gt; over the agricultural Great Plains. In June 2006 we
infer a 50% increase in soil NO&lt;sub&gt;x&lt;/sub&gt; emission and a 30% increase in
the tropospheric NO&lt;sub&gt;2&lt;/sub&gt; column relative to the June 2005–2008 mean. In a
case-study of fertilized corn and soybean fields over SE South Dakota, we
find an associated rain-induced pulsing event reaching
4.6&amp;times;10&lt;sup&gt;15&lt;/sup&gt; molec cm&lt;sup&gt;&amp;minus;2&lt;/sup&gt;, equivalent to a surface concentration of ~2 ppbv. We
calculate that soil NO&lt;sub&gt;x&lt;/sub&gt; emissions resulted in a mean daily maximum 8-h
ozone enhancement over the agricultural Great Plains of 5 ppbv in June 2006
(with predicted events reaching 16 ppbv) compared with a mean enhancement of
3 ppbv for soil NO&lt;sub&gt;x&lt;/sub&gt; in the years 2005–2008.</p>
