CMS: Forest Carbon Stocks, Emissions, and Net Flux for the Conterminous US: 2005-2010

This data set provides maps of estimated carbon in forests of the 48 continental states of the US for the years 2005-2010. Carbon (termed committed carbon) stocks were estimated for forest aboveground biomass, belowground biomass, standing dead stems, and litter for the year 2005. Carbon emissions were estimated from land use conversion to agriculture, insect damage, logging, wind, and weather events in the forests for the years 2006 - 2010. Committed net carbon flux was estimated as the sum of carbon emissions and sequestration. The maps are provided at 100-m spatial resolution in GeoTIFF format. Average annual carbon estimates, by US county, for (1) emissions for the multiple disturbance sources, (2) sequestration, and (3) the committed net carbon flux are provided in an ESRI shapefile.

本数据集提供了美国48个大陆州森林在2005至2010年间的碳含量估算地图。针对2005年的森林地上生物量、地下生物量、立枯树干和凋落物的碳储存量进行了估算。对于2006至2010年间的森林，从土地利用转换至农业、昆虫损害、伐木、风力以及天气事件中估算的碳排放量。所承诺的净碳通量估算为碳排放量与碳汇的总和。地图以100米的空间分辨率提供，格式为GeoTIFF。此外，以ESRI形状文件格式提供了按美国各郡计算的年平均碳估算数据，包括（1）来自多种干扰源的排放量，（2）碳汇量以及（3）所承诺的净碳通量。
