Dataset of ISBA open loop states and ASCAT normalized backscatter and slope data of grid points

This dataset comprises open loop simulations of the ISBA land surface model and ASCAT normalized backscatter and slope data at grid points (GPIs) containing International Soil Moisture Network stations. The dataset covers the period from 2007 to 2019 and includes a total of 31 GPIs. The ISBA land surface model runs on the offline version of SURFEX software (https://www.umr-cnrm.fr/surfex/) using ERA5 forcing data. ASCAT normalized backscatter (“sig”) data are provided at 10am and 10pm every day. If normalized backscatter are not acquired at a particular time, a value of 999 is provided.ASCAT slope (“slop”) is calculated daily following Hahn et al. (2017). These daily values are provided at 10am in this dataset. The slope value at 10pm is set to 999.本数据集包含国际土壤湿度网络（International Soil Moisture Network）站点所在网格点（grid points，简称GPIs）的ISBA陆面模式（ISBA land surface model）开环模拟结果，以及ASCAT归一化后向散射与坡度数据。数据集覆盖2007年至2019年的时段，总计包含31个网格点。ISBA陆面模式依托SURFEX软件的离线版本运行，驱动数据采用ERA5再分析数据，相关软件官网为https://www.umr-cnrm.fr/surfex/。ASCAT归一化后向散射（标记为"sig"）数据每日于上午10时与下午10时提供，若特定时刻未获取到有效数据，则以999作为填充值。ASCAT坡度（标记为"slop"）依据Hahn等（2017）的研究方法每日计算，本数据集中该坡度值仅于上午10时提供，下午10时的坡度值统一设为999。
