Meltwater runoff from Greenland becoming more erratic
A research, carried out as part of the Polar+ Surface Mass Balance Feasibility project, which used measurements from the Agency’s ice mission CryoSat, showed how Greenland’s meltwater runoff has risen by 21% over the past four decades, and has become 60% more erratic from one summer to the next. Results have just been published …
CryoSat reveals ice loss from glaciers in Alaska and Asia
Between 2010 and 2019, the Gulf of Alaska lost 76 Gt of ice per year while High Mountain Asia lost 28 Gt of ice per year. These losses are equivalent to adding 0.21 mm and 0.05 mm to sea level rise per year, respectively. The results, based on interferometric swath processing of CryoSat-2 altimeter data, …
Energy from solar wind favours the north
Using information from ESA’s Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into Earth’s atmosphere – surprisingly, more of it heads towards the magnetic north pole than towards the magnetic south pole. Read the full story. This research was supported by the ESA …
EO from Space: The Cryosphere
A new online course is about to be launched to introduce the role of satellite Earth observation (EO) technology in monitoring the Earth’s Cryosphere: it is for decision-makers, policy-makers, educators, communicators and anybody interested in learning more about monitoring glaciers, sea ice, ice caps, and areas of snow from space. Learn more on the MOOC …
20-year time-series of global primary production in the oceans
In a recent paper published in Remote Sensing, scientists used data from the Ocean Colour Climate Change Initiative to study the long-term patterns of primary production and its interannual variability. Combining long-term satellite data with in situ measurements, they assessed global annual primary productivity from 1998-2018. Being able to observe and quantify primary production over …
High resolution ET for water management from S2 and S3 combined with AI
ESA’s Sentinels for Evapotranspiration project, or Sen-ET for short, is exploiting machine learning techniques to combine Sentinel-2 and Sentinel-3 data for a 20m daily evapotranspiration monitoring in agricultural fields. Read the full story.
Greenland and Antarctica losing ice six times faster than expected
According to IMBIE (Ice Sheet Mass Balance Inter-comparison Exercise) most recent analyses, Greenland and Antarctica lost 6.4 trillion tonnes of ice between 1992 and 2017 – pushing global sea levels up by 17.8 millimetres, on track with the Intergovernmental Panel on Climate Change’s worst-case climate warming scenario.

Water detection and monitoring in Sub-Saharan Africa made easy with QuantEO
The movie above is demonstrating how the QuantEO service may be used to detect water over time in Sub Saharan Africa from Senegal to Ethiopia. This is a sample application of the service, developed by Pixstart within an Open Call project, which allows to produce classified Sentinel-2 images on demand and near real time …
