Data archive for journal paper "Assimilation of Sentinel-1 Backscatter into a Land Surface Model with River Routing and Its Impact on Streamflow Simulations in Two Belgian Catchments"
收藏资源简介：
The datasets archived here include data assimilation results presented in the journal paper, "Assimilation of Sentinel-1 Backscatter into a Land Surface Model with River Routing and Its Impact on Streamflow Simulations in Two Belgian Catchments" (https://doi.org/10.1175/JHM-D-22-0198.1). The output was produced by combining land surface modeling (Noah-MP with HYMAP river routing) and Sentinel-1 backscatter data, applying a 1D Ensemble Kalman Filter using the NASA Land Information System. We provide Netcdf daily output files for 6 different experiments - OLfd and OLgw: model-only (open-loop, OL) for two different model settings (fd: free drainage and gw: SIMTOP groundwater option) - DASMfd and DASMgw: data assimilation (DA) with soil moisture (SM) updating for two different model settings (fd: free drainage and gw: SIMTOP groundwater option) - DASMLAIfd and DASMLAIgw: data assimilation (DA) with soil moisture (SM) and leaf area index (LAI) updating for two different model settings (fd: free drainage and gw: SIMTOP groundwater option) Each experiment directory contains five subdirectories (DAOBS, EnKF, ROUTING, RTM, SURFACEMODEL) with corresponding outputs as described in https://nasa-lis.github.io/LISF/LIS_users_guide/LIS_users_guide.html
本存档数据集包含发表于期刊论文《将Sentinel-1后向散射数据同化至带河道汇流的陆面模型及其在比利时两个流域的径流模拟影响》（DOI: 10.1175/JHM-D-22-0198.1）中的数据同化结果。该数据集的输出结果通过融合陆面模拟（搭载HYMAP河道汇流模块的Noah-MP模型）与Sentinel-1后向散射数据，并依托美国国家航空航天局（National Aeronautics and Space Administration, NASA）陆面信息系统（Land Information System, LIS）运行一维集合卡尔曼滤波（Ensemble Kalman Filter, EnKF）生成。本数据集提供6组不同试验的NetCDF（Network Common Data Form）每日输出文件，具体包括： - OLfd与OLgw：仅运行模型的开环（open-loop, OL）试验，对应两种不同模型设置（fd：自由排水模式，gw：SIMTOP地下水模块选项）； - DASMfd与DASMgw：针对上述两种模型设置，仅同化土壤湿度（soil moisture, SM）的数据同化（data assimilation, DA）试验； - DASMLAIfd与DASMLAIgw：针对上述两种模型设置，同时同化土壤湿度与叶面积指数（leaf area index, LAI）的数据同化试验。 每个试验目录均包含五个子目录（DAOBS、EnKF、ROUTING、RTM、SURFACEMODEL），各子目录对应的输出内容详见https://nasa-lis.github.io/LISF/LIS_users_guide/LIS_users_guide.html
