SURFEX-MEGAN3.0 analysis based BVOC emissions

Biogenic volatile organic compound (BVOC) emissions calculated using a coupled modelling system consisting of the SURFEX land surface model and the MEGAN3 BVOC emission model. These emissions were calculated using the SURFEX model in analysis (i.e., data assimilation of leaf area index observations) configuration over the time period 2018-2020. The emissions are calculated over the Copernicus Atmospheric Monitoring Service European domain at a spatial resolution of 0.1 x 0.1 degree. The emissions are calculated for the RACM chemical mechanism. The data are in zipped netcdf format. Each file represents a single chemical species for a single month in the time period January 2018-December 2020.本数据集为采用由SURFEX陆面模型与MEGAN3 BVOC排放模型组成的耦合建模系统计算得到的生物源挥发性有机化合物（Biogenic Volatile Organic Compound，BVOC）排放量。该排放量以2018至2020年为时间范围，采用配置了数据分析模式（即叶面积指数观测数据同化）的SURFEX模型完成计算。计算区域覆盖哥白尼大气监测服务（Copernicus Atmospheric Monitoring Service）欧洲范围，空间分辨率为0.1°×0.1°。本次排放量计算基于RACM化学机理实现，数据以压缩netCDF格式存储。2018年1月至2020年12月期间，每个文件对应单个月份的单种化学组分。
