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个大陆州在2005年至2010年期间森林估算碳含量的地图。对于2005年，估算的碳储存量包括地上生物量、地下生物量、立枯树干和凋落物的承诺碳。2006年至2010年期间，估算的碳排放量源自土地利用转换至农业、昆虫损害、砍伐、风力以及森林中的天气事件。承诺的净碳通量被估算为碳排放量和碳汇的总和。地图以100米的空间分辨率以GeoTIFF格式提供。此外，按美国各郡平均年度碳估算值，包括（1）多种干扰源的排放、（2）碳汇以及（3）承诺的净碳通量，均以ESRI形状文件格式提供。
