Forest carbon flux data for Berau, Indonesia

These data and codes support a method for estimating the relevant historic forest carbon fluxes within the Regency of Berau in eastern Borneo, Indonesia. Our method integrates best available global and local datasets, and includes a comprehensive analysis of uncertainty at the regency scale. There are four associated files: 1) BFCP_MonteCarlo_FINAL_FOR_SUBMISSION.R : R code for calculating rate of historic Land use change emissions in Berau Regency, East Kalimantan, Indonesia. Includes Monte Carlo simulation for propagating uncertainty; 2) ForestStrataMap.rar: Compressed raster file of Forest Strata map used to stratify C-flux calculations. Includes the following attributes in a 30x30 m raster: --Forest Stratum name --Above-ground live biomass (AGLB) carbon stocks (in MG/ha) --standard deviation of mean carbon stocks --the number of GLAS shots used to calculate the means; 3) GLASshots.xlsx: contains the raw values for the GLAS shots used to estimate AGLB values for forest strata, including "model-based" error for each shot (XLSX); 4) GLAS_CalibrationFieldPlots.zip: contains the raw data for the field plots used to calibrate the GLAS biomass values for our study region.

本数据集与配套代码可用于估算印度尼西亚婆罗洲东部伯劳摄政区（Regency of Berau）内的相关历史森林碳通量。本研究方法整合了当前可获取的最优全球与本地数据集，并针对摄政区尺度开展了全面的不确定性分析。配套文件共4项：
1) BFCP_MonteCarlo_FINAL_FOR_SUBMISSION.R：用于计算印度尼西亚东加里曼丹省伯劳摄政区历史土地利用变化排放速率的R代码，包含用于不确定性传递的蒙特卡洛（Monte Carlo）模拟模块；
2) ForestStrataMap.rar：用于分层开展碳通量计算的森林分层图压缩栅格文件，该分辨率为30米×30米的栅格包含以下属性：——森林分层名称——地上活体生物量（Above-ground live biomass，AGLB）碳储量（单位：MG/ha）——碳储量均值的标准差——用于计算均值的GLAS（Geoscience Laser Altimeter System）光斑数量；
3) GLASshots.xlsx：包含用于估算森林分层地上活体生物量的GLAS光斑原始数值，其中包含每个光斑的“基于模型的”误差（XLSX格式）；
4) GLAS_CalibrationFieldPlots.zip：包含用于校准本研究区域GLAS生物量数值的野外样地原始数据。
