Global Forest Biomass http://webarchive.iiasa.ac.at/Research/FOR/biomass.html This work presents a technique to downscale the aggregated results of the FRA2005 from the country level to a half degree global spatial dataset containing forest growing stock; above/belowground biomass, dead wood and total forest biomass; and above-ground, below-ground, dead wood, litter and soil carbon. The downscaling method is derived using a relationship between net primary productivity (NPP) and biomass and the relationship between human impact and biomass assuming a decrease in biomass with an increased level of human activity. The results, presented here, represent one of the first attempts to produce a consistent global spatial database at half degree resolution containing forest growing stock, biomass and carbon stock values.

结合MCD45燃烧面积产品以及国际灾害数据库EM-DAT提供的灾害数据，筛选具有一定规模的195个森林火灾事件，得到2000-2015年全球森林大火分布与大火频率数据集。该数据集主要包括：（1）2000-2015年195次全球森林大火的空间分布地理位置数据；（2）2000-2015年全球森林大火的发生次数即频率统计数据。结果表明：全球范围内，火灾发生频率高的地区包括：北美洲太平洋沿岸、欧洲南部、大洋洲、中国东北部；时间上，在 2000-2015年期间，全球平均每年发生火灾次数12次左右，其中，2002年全球发生火灾次数最多，共计29次，2014年和2008年发生森林火灾次数最少，分别为5次。
