Title: Determination of smoke plume and layer heights using scanning lidar data

Author: Kovalev, Vladimir A.; Petkov, Alexander; Wold, Cyle; Urbanski, Shawn; Hao, Wei Min

Date: 2009

Source: Applied Optics. 48(28): 5287-5294.

Publication Series: Scientific Journal (JRNL)

Description: The methodology of using mobile scanning lidar data for investigation of smoke plume rise and high-resolution smoke dispersion is considered. The methodology is based on the lidar-signal transformation proposed recently [Appl. Opt. 48, 2559 (2009)]. In this study, similar methodology is used to create the atmospheric heterogeneity height indicator (HHI), which shows all heights at which the smoke plume heterogeneity was detected by a scanning lidar. The methodology is simple and robust. Subtraction of the initial lidar signal offset from the measured lidar signal is not required. HHI examples derived from lidar scans obtained with the U.S. Forest Service, Fire Sciences Laboratory mobile lidar in areas polluted by wildfires are presented, and the basic details of the methodology are discussed.

Keywords: smoke plume, lidar data, atmospheric heterogeneity height indicator (HHI)
