SMAP(Soil Moisture Active and Passive) 是美国的地球观测卫星之一,2015年1月31日发射升空。从名字就可以知道,SMAP主要为了观测土壤水分,并且有主动的传感器和被动的传感器。主动的传感器是L波段雷达,被动的传感器是L波段微波辐射计。计划中,雷达和辐射计各自生产3km和36km的土壤水分产品,并协同生产9km的土壤水分产品。

Level 3 soil moisture datasets from the recently launched Soil Moisture Active Passive (SMAP) satellite are evaluated for drought monitoring inrangelands. • Validation of SMAP soil moisture (SSM) within situand modeled estimates showed high level of agreement. ...
Spatially and temporally downscaled data from the upcoming Soil Moisture Active Passive (SMAP) mission can fill this data gap through the generation of fine resolution soil moisture maps that can be incorporated into DSSAT-CSM model. This study will explore the impact downscaled remotely-sensed ...
We used data from NASA’s Soil Moisture Active Passive (SMAP) Mission, in particular version 3 of the L3 Enhanced Global 9-km product26(SMAP L3E). Relative to other satellites, the SMAP L-Band microwave sensor tends to offer the best sensitivity to soil moisture retrieval at the top 5...
