2015-08-03 Very high UHSAS concentrations (>500 /cm3) extending over much of the day. CO ~ 125 ppbv
2017-08-22 There is biomass burning aerosol in the column (look at worldview imagery and MODIS AOD) but it doesn't appear to have a particularly strong signature at the surface aerosol measurements. Potential for interaction with mid-level clouds though, since precipitating features extend to around 3 km.
