Coastal Satellite Altimetry data, including those from ESA's Envisat mission, have not been fully exploited yet, because the sea level estimation in coastal areas is considered unreliable.
The latest release of NEST (NEXT ESA SAR Toolbox) 5.1 is available for free on the NEST website.
Oceanic internal waves play an important role in nutrient distribution, primary productivity, acoustic propagation, coral reef growth, and submarine navigation. It is very difficult to measure the internal wave field because it has a complex three-dimensional structure and its motion is affected both by the structure of vertical stratification and by horizontal mean currents.
Over the last year, engineers have been carefully testing and piecing together the multitude of components that make up Sentinel-3. The recent arrival of the infrared radiometer is a milestone in the exacting process of building this upcoming Copernicus mission.
Launched on 3 April, ESA's Sentinel-1A satellite has already delivered its first radar images of Earth. They offer a tantalising glimpse of the kind of operational imagery that this new mission will provide for Europe's ambitious Copernicus environmental monitoring programme.
The fourth annual Copernicus Masters competition is just around the corner. Ideas for services, business concepts and applications based on satellite Earth observation data can be submitted starting on 15 April.
Last Sunday, 06 April 2014 at 3:54 UTC, the first Sentinel-1A signal transmitted in X-Band was successfully acquired at the Matera ground station, South Italy.
Two days after launch, the first Sentinel satellite for Europe's Copernicus programme has passed its initial instrument checks and technical verifications of the ground segment.
Following its launch yesterday, Sentinel-1A has performed a carefully choreographed 10-hour dance routine to open its large radar antenna and solar wings.
The ability of European citizens, policymakers and service providers to access key environmental data on a routine basis will take a major step forward following the launch today of ESA’s Sentinel-1A satellite.
Calling on all interested users of Sentinel data, who would like to submit their results, turning their experiences into 'success stories'.
If you have a good story to tell, of how any of the Sentinel satellites are producing data that bring benefit to your work and/or to society, please contact the Sentinel Online Editor Malì Cecere at: mali.cecere@ejr-quartz.com with your proposals.
