Short summary
Combining satellite and urban air pollution measurements with a meteorology and air quality model, we present the state of air quality in Colombia. We found four distinctly different emission regimes. The simulated pollution levels compare well with satellite data, but the comparison also indicates misrepresentation of prescribed fire emissions and simulated lightning emissions. Comparison of urban measurements requires careful consideration of (nocturnal) boundary layer dynamics and advection.
