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

这项美国-巴西奖支持两名博士之间为期三年的合作研究。华盛顿大学的托马斯·h·欣克利、大卫·v·桑德伯格和埃内斯托·阿尔瓦拉多，以及西班牙国家森林火灾研究所的若昂·安德拉德·德·卡瓦略博士，他们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林火中热带生物质的燃烧和阴燃，以及为林火而砍伐的空地附近原始森林的可燃性变化。该项目包括在受控环境条件下，在风洞中对原始森林采伐后的开阔刀削面燃烧和热带森林的实验室燃烧进行测量。将在巴西亚马逊森林马托格罗索州阿尔塔弗洛雷斯塔附近的农场进行开放式控制火灾。实验室实验将在巴西国家空间研究所的燃烧和推进实验室进行。该奖项将促进热带森林和稀树草原火灾危险评级能力的发展，为控制亚马逊地区火灾影响提供更好的指导方针，并改进对热带生态系统释放和封存的碳的估计。＊＊＊

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. ***
