lidar to observe both prescribed and wild fires. Figure 8 shows Doppler lidar measurements of
plumes over Helsinki produced from forest fires in North West Russia. The correlation
between the lidar backscatter data and the retrieved vertical velocities shows convective
updrafts containing the particulate-laden air from the cleaner air contained in downdrafts.
