Soil Moisture Active Passive (SMAP) L4 Carbon Ancillary Surface Meteorological Forcing Data, Version 1

This ancillary SMAP product contains dynamic surface meteorological forcing data. The meteorological model is derived from the Modern-Era Retrospective Analysis for Research and Applications (MERRA) data set and used as an input in the SMAP L4 Carbon algorithm. The forcing data is processed from hourly GEOS-5 files into daily values. Daily files are processed every eight days.

本辅助SMAP产品包含动态地表气象强迫数据。该气象强迫数据源自现代研究与应用再分析数据集（Modern-Era Retrospective Analysis for Research and Applications，MERRA），并被用作SMAP四级碳算法的输入参数。该强迫数据由逐小时GEOS-5文件处理为日均值数据，日数据文件每8天更新一次。
