Soil Moisture Active Passive (SMAP) L4 Soil Moisture Ancillary LDAS Parameters Files, Version 1

This ancillary SMAP product contains three dynamic Land Data Assimilation Systems (LDAS) data sets. These data sets include Brightness Temperature (TB) scaling parameters; catchment model parameters such as topographic statistics, soil texture, and soil hydraulic parameters; and LDAS L-band microwave radiative transfer model parameters.

本辅助SMAP产品包含三套动态陆地数据同化系统（Land Data Assimilation Systems, LDAS）数据集。这些数据集涵盖亮温（Brightness Temperature, TB）尺度参数、流域模型相关参数（包括地形统计特征、土壤质地与土壤水力参数）以及LDAS的L波段微波辐射传输模型参数。
