15 September 1993 Characterization of the visibility of wildfire smoke clouds
Author Affiliations +
In order to investigate the smoke cloud visibility of small wildfires a series of controlled biomass burning experiments has been carried out to investigate the characteristics of smoke clouds using various remote sensing techniques. These techniques include simultaneous scattering and transmission measurements in four wavelength bands, near-, mid-, and far- infrared video imagery, high resolution Fourier spectrometry, and particle size distribution measurements. The characterization and, in particular, knowledge on the contrast of smoke from small, beginning wildfires against a vegetation background is required in order to predict the performance of autonomous surveillance systems. This paper describes the preliminary analysis of experiments which have been carried out in Ypenburg (the Netherlands) in 1992. The results of these experiments are used to estimate the wildfire detection efficiency of a demonstration sensor which is being developed in a project financed by the Commission of the European Communities and by Bosschap. The autonomous wildfire detection sensor is described.
