Sentinel-1 & Sentinel-2 for SOIL Moisture Retrieval at Field Scale

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Soil moisture content is an essential climate variable that is operationally delivered at low resolution (e.g. 36-9 km) by earth observation missions, such as ESA/SMOS, NASA/SMAP and EUMETSAT/ASCAT. However numerous land applications would benefit from the availability of soil moisture maps at higher resolution.

Status and Evolution of the Sentinel-1 Mission

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The routine operations of the Copernicus Sentinel-1 mission constellation are on-going and performed at full mission capacity. The C-band SAR mission is characterized by large-scale and repetitive observations, systematic production and free and open data policy. Sentinel-1 data are routinely used by Copernicus and many operational services, and in the

Analysis of Sentinel-1 mission capabilities

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The Sentinel-1 mission is designed to be a source of continuous and reliable collection of C-band SAR imagery. Requirements for Sentinel-1 end to end system, as part of the complete family of GMES Sentinels, guarantee continuity of C-band SAR data and products availability to operational entities who exploit satellite radar imagery since ERS 1 ...

Sentinel-1 mission operations concept

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In line with the overall Sentinel operations strategy, Sentinel-1, the next European C-Band SAR mission following ERS and ENVISAT, will be operated based on a stable and predefined observation scenario. During the Full Operations Capacity of the mission, this observation scenario will make optimum use of the SAR duty cycle within the technical ...

AGB estimation using Sentinel-2 and Sentinel-1 datasets

Environmental Monitoring and Assessment
Climate change is one of the greatest threats recently, of which developing countries are facing most of the brunt. In the fight against climate change, forests can play an important role, since they hold a substantial amount of terrestrial carbon and can therefore affect the global carbon cycle.

Sentinel-1 multitemporal SAR products

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
In this paper, we present a new framework for high-level processing of time series images, with particular reference to Sentinel-1 data. The proposed methodology has the goal of enhancing the interpretation of SAR imagery through the production of physical-based RGB composites, which are particularly suited for being easily interpreted by the human ...

Prospects of Sentinel-1 for land applications

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Sentinel-1 mission is a polar-orbiting satellite constellation for the continuation of C-band Synthetic Aperture Radar (SAR) applications. Contrary to its predecessor instruments onboard of ENVISAT and RADARSAT, the Sentinel-1 satellites will be operated following a predefined and fixed baseline acquisition scenario.
