Fire Particulate Emissions from Combined VIIRS and AHI Data for Indonesia, 2015-2020

This dataset provides 10-minute fire emissions within 0.1-degree regularly spaced intervals across Indonesia from July 2015 to December 2020. The dataset was produced with a top-down approach based on fire radiative energy (FRE) and smoke aerosol emission coefficients (Ce) derived from multiple new-generation satellite observations. Specifically, the Ce values of peatland, tropical forest, cropland, or savanna and grassland were derived from fire radiative power (FRP) and emission rates of smoke aerosols based on Visible Infrared Imaging Radiometer Suite (VIIRS) active fire and aerosol products. FRE for each 0.1-degree interval was calculated from the diurnal FRP cycle that was reconstructed by fusing cloud-corrected FRP retrievals from the high temporal-resolution (10 mins) Himawari-8 Advanced Himawari Imager (AHI) with those from high spatial-resolution (375 m) VIIRS. This new dataset was named the Fused AHI-VIIRS based fire Emissions (FAVE). Fire emissions data are provided in comma-separated values (CSV) format with one file per month from July 2015 to December 2020. Each file includes variables of fire observation time, fire geographic location, classification, fire radiative energy, various fire emissions and related standard deviations.

本数据集提供了从2015年7月至2020年12月期间，印度尼西亚境内以0.1度等间隔规律分布的10分钟火源排放数据。该数据集基于从多颗新一代卫星观测中得出的火辐射能量（FRE）和烟雾气溶胶排放系数（Ce），采用自上而下的方法生成。具体而言，Ce值是通过从可见光红外成像仪套件（VIIRS）的活跃火源和气溶胶产品中获取的火辐射功率（FRP）以及烟雾气溶胶的排放速率，针对沼泽、热带森林、农田、草原和草地等不同类型地表进行推导。每个0.1度间隔的FRE值，是通过融合高时间分辨率（10分钟）的Himawari-8高级Himawari成像仪（AHI）的云校正FRP反演结果与高空间分辨率（375米）的VIIRS数据，重建日间FRP周期计算得出。此新数据集被命名为融合AHI-VIIRS火源排放（FAVE）。火源排放数据以逗号分隔值（CSV）格式提供，每月一个文件，涵盖2015年7月至2020年12月。每个文件包含火灾观测时间、火灾地理位置、分类、火辐射能量、多种火源排放及其相关标准偏差等变量。
