Tracking the extent of wildfire smoke using satellite and ground-based observations

Fire produces aerosols (smoke) that can be transported short or long distances. Satellites and ground-based monitors each have strengths and weaknesses for characterizing the horizontal extent of smoke and its concentration at the surface. With imagery and aerosol optical depth (AOD) retrievals from geostationary, polar orbiting and airborne remote sensing, along with ground-based observations from regulatory-grade as well as low-cost monitors, we see a more complete picture of smoke distribution and movement. Here we look at some recent smoke events of different magnitudes and intensities, and use animations to qualitatively link total-column and surface concentrations.
