Most of us probably wouldn't think of describing snow in terms of its grain size. However, grain size is fundamental to the amount of sunlight that snow reflects back into space - its albedo. With both snow and albedo part of the climate system, scientists are applying a novel analytical theory to Copernicus Sentinel-3 data and shedding new light on Greenland's changing albedo.
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth's surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate crisis and causing immediate problems for local communities.

Scientists are gathering in the Azores this week to share findings on how satellite has revealed changes in the height of the sea, ice, inland bodies of water and more. Of concern to all is the fact that global sea level has not only been rising steadily over the last 25 years, but recently it is rising at a much faster rate.

The main proof of long hot and dry spell Europe has been enduring over the last few weeks has been obtained from the Copernicus Sentinel-3 images acquired on 28 June and 25 July 2018.

These Copernicus Sentinel-3 images show how this year's heatwave has taken its toll on vegetation in northern Germany, Denmark and Sweden.
25 July 2018
With temperatures soaring and no rain to speak of, Europe is the grip of a heatwave. As well as the havoc that wildfires have caused in countries such as the UK, Sweden and Greece, the current heat is scorching our land and vegetation.
20 July 2018
With Europe in the grip of a heatwave and little rain, the scorched ground and dry vegetation is succumbing to fire. Fires have now broken out as far as the Arctic Circle, in Sweden. This animation shows images from the Copernicus Sentinel-2 and Sentinel-3 missions.

This week marks 20 years since the manifesto was signed that gave rise to Europe's Copernicus environmental programme. With seven Sentinel satellites already in orbit delivering terabytes of data every day, Copernicus is the biggest provider of Earth observation data in the world.

The key to monitoring Earth's changing environment and to guaranteeing a consistent stream of satellite data to improve our daily lives is to take the same measurements over the course of decades. But how do you know that measurements from successive satellites, even though identical in build, are like for like?

Launched on 25 April 2018, Sentinel-3B has already delivered some impressive first images from its ocean and land colour instrument, from its altimeter and from the optical channels of its radiometer.
With the radiometer's thermal-infrared channels now turned on, the satellite completes its set of firsts with an image that depicts thermal signatures over southern Italy, the Mediterranean Sea and Sicily.

Launched on 25 April 2018, the Sentinel-3B satellite has already delivered impressive first images from its ocean and land colour instrument and from its radiometer. It has now also delivered data from its altimeter – which means that all of the instruments are working well.

Less than two weeks after it was launched, the Copernicus Sentinel-3B satellite has delivered its first images of Earth. Exceeding expectations, this first set of images include the sunset over Antarctica, sea ice in the Arctic and a view of northern Europe.
26 April 2018
With the launch of Sentinel-3B, the first set of Sentinels for Copernicus is now in orbit delivering an almost mind-boggling amount of data. While this wealth of information advances environmental monitoring, it also opens up huge business opportunities. To help bring these data to market, ESA and SAP have joined forces to create the World Space Alliance.

The second Sentinel-3 satellite, Copernicus Sentinel-3B, was launched on 25 April, joining its identical twin Sentinel-3A in orbit. This pairing of satellites increases coverage and data delivery for the European Union's Copernicus environment programme.
24 April 2018
The launch of Sentinel-3B will complete the Sentinel-3 constellation and represents the culmination of months of training to fly Europe's latest Copernicus satellite.
23 April 2018
The next Sentinel satellite for Europe's environmental monitoring Copernicus programme is poised for liftoff from the Plesetsk cosmodrome in northern Russia.
13 April 2018
Getting a satellite ready to be launched involves a long list of jobs, but with the Copernicus Sentinel-3B satellite now fuelled, this particular 'to do' list is significantly shorter. And, importantly, all is on track for lift-off on 25 April.
03 April 2018
Awarding outstanding ideas and applications that use Earth observation data to tackle challenges faced by business and society, the Copernicus Masters 2018 competition is now open for submissions.
