From: Unusually high soil nitrogen oxide emissions influence air quality in a high-temperature agricultural region

Figure 4

Surface concentrations of NO2 measured at an air quality monitoring station (obs) in El Centro, CA (CA Air Resources Board) and modelled with WRF-Chem (mod) and WRF-Chem with soil NO2 emission rates multiplied by 10 (mod*10) and 64.5 × (mod*64.5). All data are from 23 to 29 September 2012.
