LBA-ECO LC-08 Ecosystem Demography Model Estimated C, NPP, and Biomass For Amazonia

This data set provides Ecosystem Demography Model (ED) estimates of potential above-ground net primary production (NPP) (kg C/m2/y), potential average live biomass (kg C/m2), and potential average soil carbon (kg C/m2) for the Brazilian Amazon at 1 degree resolution.

Ecosystem Demography Model predicts both ecosystem structure (e.g. above and below-ground biomass, vegetation height and basal area, and soil carbon stocks) and corresponding ecosystem fluxes (e.g. NPP, NEP, and evapotranspiration) from climate, soil, and land-use inputs. Estimates for the Brazilian Amazon include the effects of natural disturbances such as windthrow and fire, but do not include the effects of human land use. To produce these estimates, ED was forced with ISLSCP I data for 1987 and 1988 and averaged into a single average year (Moorcroft et al., 2001).

The data are provided for the three estimates in both ASCII text and in NetCDF formatted files.

本数据集提供了生态系统人口模型（ED）对巴西亚马逊地区潜在地上净初级生产量（NPP）（千克碳/平方米/年）、潜在平均活生物量（千克碳/平方米）和潜在平均土壤碳含量（千克碳/平方米）的估计值，数据分辨率为1度。生态系统人口模型能够基于气候、土壤和土地利用输入预测生态系统结构（例如地上及地下生物量、植被高度和基面积、土壤碳储量）及其相应的生态系统通量（例如NPP、NEP和蒸散量）。对于巴西亚马逊地区的估计值考虑了自然干扰（如风倒和火灾）的影响，但未包含人为土地利用的影响。为生成这些估计值，ED模型使用1987年和1988年的ISLSCP I数据进行了驱动，并平均为单一的平均年份（Moorcroft等，2001年）。数据以ASCII文本格式和NetCDF格式文件提供。
