ESA’s CryoSat mission reveals 10 years of glacier ice loss

Thanks to ESA’s CryoSat satellite and a breakthrough way of using its data, scientists have discovered that glaciers worldwide have shrunk by a total of 2% in just 10 years, and it’s because of higher air temperatures.

Copernicus Sentinel-6 ready for launch

Final preparations are underway in California for the launch of Sentinel-6 Michael Freilich, a joint European and US satellite designed to take precise measurements of sea-level change. The satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ a radar altimeter to map sea-surface topography. The satellite will provide fundamental data for climate science and policymaking, helping to protect the 600 million people who live in vulnerable coastal areas. It will also deliver near-realtime information for marine and weather forecasts.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French space agency CNES. Scheduled for launch on 21 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base on the California coast, the satellite is named Michael Freilich after NASA’s former Director of Earth Science.

Copernicus Sentinel-6 measuring sea levels using radar altimetry

This November the newest member of the EU’s Copernicus programme, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA’s former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French space agency CNES. It will continue a three-decade-long time-series of radar altimetry missions that started with the Topex-Poseidon mission and was then followed by the Jason missions.

Copernicus Sentinel-6 Michael Freilich: preparing for launch

A European satellite built to carry out precise measurements of sea level changes has arrived in California in preparation for launch. The Sentinel-6 Michael Freilich satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ radar to map sea surface topography.

The mission will be used to monitor the height of the sea surface to understand long-term change. It will also measure wave height and wind speed. The satellite will provide fundamental data for climate science, policy-making and protecting the 600 million people who live in vulnerable coastal areas.

Data are provided to Copernicus services in near-real time to improve marine and weather forecasts used by maritime and coastal communities.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French Space Agency CNES.

It is named Michael Freilich after NASA’s former Director of Earth Science and is scheduled for launch on 10 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base.

ESA Euronews: Studying climate threats with Sentinel

The most recent trends in sea level rise mean the low-lying Camargue region of southern France could be submerged by the sea by the end of the century.

The sea walls built along the coast in the 1980s have already been broken by the waves, as a combination of rising waters, slowly sinking landmass, and reduced amounts of sediment from the Rhone river spell trouble for this environment.

Anis Guelmami uses Copernicus Sentinel satellites to study wetlands like the Camargue, and he tells us the latest news from space.

Sea-level rise

Although it may not be immediately obvious when we visit the beach, sea-level rise is affecting coastlines all over the world. For low-lying countries such as the Netherlands, sea-level rise and tidal surges are a constant threat. Our oceans are rising as a consequence of climate change. As the temperature of seawater increases it expands and the ice melting from ice sheets and glaciers adds more water to the global ocean. We know this because satellites high above our heads measure the temperature of the sea surface and of our changing ice.

While the global averaged trend is towards rising levels, there are many regional differences so that in some places it is rising and in other places it is falling. Satellites carrying altimeter instruments systematically measure the height of the sea surface so that sea-level rise can be closely monitored. Altimetry measurements over the last 25 years show that on average sea-level is rising about 3 mm a year and this rise is accelerating.

Contributors to sea-level rise

The physical processes causing global sea-level rise are highlighted in the animation. The main causes are thermal expansion of oceans, as they accumulate the excess heat caused by greenhouse gas emissions, the melting of ice from the ice sheets and glaciers, as well as changes in land water storage such as lakes. Regionally, sea level changes vary quite dramatically. The reasons for this are different to the global causes of sea-level changes and include changes to sea water density, influenced by salinity and temperature.

ESA Euronews: Space for Earth

We have all heard of climate change, but what’s really happening to our planet now, in November 2015? As the COP21 summit in Paris looms in December, we set out to establish some of the scientific fundamentals, and hear how space technology is being used to get a truly global view of Earth’s vital signs.

Near Les Deux Alps in the French Alps, some 3,200 metres above sea level, we look at how satellite data and glacier measurements can help us to understand the effects of global warming with remote sensing scientist Jean-Pierre Dedieu.
