U.S.-Brazil Cooperative Research: Biomass Combustion in Brazilian Forest Fires

Hinckley 9908547这个美国-巴西奖项支持托马斯H。华盛顿大学的欣克利、大卫V.桑德伯格和埃内斯托阿尔瓦拉多，以及国家空间研究所的若昂安德拉德德卡瓦略博士，对巴西亚马逊森林火灾中的生物质燃烧进行了研究。 合作者将开发一种建模方法，以评估巴西亚马逊森林中热带生物质的燃烧和阴燃燃烧，以及与为燃烧而砍伐的皆伐地相邻的原始森林可燃性的变化。 该项目包括在受控环境条件下对砍伐的原始森林的露天采伐迹地燃烧和在风洞中对热带木材的实验室燃烧进行燃烧测量。 巴西亚马逊森林中马托格罗索州阿尔塔弗洛雷斯塔附近的农场将进行开放控制的火灾。 实验室实验将在巴西国家空间研究所燃烧和推进实验室进行，这一奖项将导致发展热带森林和热带草原的火灾危险评级能力，改进亚马逊地区控制火灾影响的准则，并改进对热带生态系统释放和固碳的估计。***

Hinckley9908547This US-Brazil award supports a three year collaborative research between Drs. Thomas H. Hinckley, David V. Sandberg, and Ernesto Alvarado, of the University of Washington, and Dr. Joao Andrade de Carvalho of the Instituto Nacional de Pesquisas Espaciais for a study of biomass combustion in Brazilian Amazon forest fires. The collaborators will develop a modeling methodology to assess the flaming and smoldering combustion of tropical biomass from slash fires in the Brazilian Amazon forest, and the change in flammability of primary forest adjacent to the deforested clearcuts created for the slash burns. The project consists of combustion measurements of open slash burn from deforested primary forest and laboratory burning of tropical woods in a wind tunnel under controlled environmental conditions. Open controlled fires will be conducted in farms near Alta Floresta, Mato Grosso in the Brazilian Amazon forest. Laboratory experiments will be conducted at the Combustion and Propulsion Laboratory of the Brazil's National Institute of Space Research.This award will lead to the development of fire-danger rating capability for tropical forests and savannahs, better guidelines for controlling the effects of fires in the Amazon Region, and an improved estimate of the carbon released and carbon sequestered by tropical ecosystems. ***
