The Potential of Sentinel-1 for Monitoring Soil Moisture with a High Spatial Resolution at Global Scale
نویسندگان
چکیده
The European Space Agency is currently developing Sentinel-1, a constellation of two polar-orbiting C-band radar satellites for operational Synthetic Aperture Radar (SAR) applications. The Sentinel-1 mission is designed for continuous and operational monitoring. The goal is to map the European land mass once every four days in Interferometric Wide Swath (IWS) mode, and the global land surface at least once every 12 days. Because such a high temporal sampling rate is expected to be very useful for monitoring soil moisture and other dynamic hydrologic process variables, we discuss the potential of the Sentinel-1 SAR mission for global soil moisture monitoring.

Estimation of Soil Moisture Index Using Multi-Temporal Sentinel-1 Images over Poyang Lake Ungauged Zone
The C-band radar instruments onboard the two-satellite GMES Sentinel-1 constellation provide global measurements with short revisit time (about six days) and medium spatial resolution (5 × 20 m), which are appropriate for watershed scale hydrological applications. This paper aims to explore the potential of Sentinel-1 for estimating surface soil moisture using a multi-temporal approach. To this...

To support the operational use of Synthetic Aperture Radar (SAR) earth observation systems, the European Space Agency (ESA) is developing Sentinel-1 radar satellites operating in C-band. Much like its SAR predecessors (Earth Resource Satellite, ENVISAT, and RADARSAT), the Sentinel-1 will operate at a medium spatial resolution (ranging from 5 to 40 m), but with a greatly improved revisit period,...

Availability of soil moisture observations at a high spatial and temporal resolution is a prerequisite for various hydrological, agricultural and meteorological applications. In the current study, a novel algorithm for merging soil moisture from active microwave (SAR) and passive microwave is presented. The MAPSM algorithm—Merge Active and Passive microwave Soil Moisture—uses a spatio-temporal ...

The potential of the ERS-1/2 scatterometer global soil moisture product has been shown in several studies. The ASCAT sensor on-board the METOP satellite is extending the 16 year time series of the ERS-1/2 scatterometer as a source for extracting information for ocean and land applications. Calibrated ASCAT data will continue the scatterometer global soil moisture archive while improving both th...
