<p>This dataset documents local tractor activity at the S2 (Mt. Airy) site during CoURAGE.

Data flags are as follows:&nbsp;</p><p>1 = confirmed no local tractor influence on aerosol measurements</p><p>2 = one data indicator is present (extreme PM10/PM2.5 ratio OR visual confirmation of tractor sighting), but not both</p><p>3 = both data indicators confirm local tractor influence on aerosol</p><p>0 = missing data, no determination possible</p>
