First Results of CCI Snow Project: Towards a Global Time Series of Snow Extent

The Snow CCI project team recently presented a poster of initial project results at the Living Planet Symposium in Milan earlier this year. The pos, as part of a wider effort to develop a long time series of daily global snow extent maps from satellite data.

They show snow mapping based on Normalized Difference Snow Index improved by using a cloud mask and uncertainty measures. AVHRR GAC satellite data, pre-processed by the CCI cloud project, was used to improve geocoding and apply inter-channel calibration. 

New team member: Sophie Hebden, ESA/Future Earth liaison officer


​Sophie Hedben joins the ESA Climate Office as part of a secondment from the global sustainability research network Future Earth and is charged with managing joint activities to maximise the use of CCI data.

Research takes steps to improve the ocean wave climate record 

Work by the Climate Change Initiative’s Sea State project team has produced a new long-term global record of ocean waves that is helping to understand the evolution of marine climate and its impacts. 

NEW DATA: Ocean Colour version 4 Dataset Release

Ocean Colour version 4 Dataset Release


The latest version of the Ocean Colour_cci dataset version 4.0 is available.

The dataset now extends across two decades to the end of December 2018 and is an update of the version 3.1 product that includes NASA's most recent reprocessing (R2018) updates for MODIS-Aqua, VIIRS and SeaWiFS.  This included significant recalibration for MODIS to address noticeable drift in trends resulting from sensor decay.

What’s happening to Greenland’s ice?

A new paper, led by Ruth Mottram of the Danish Meteorological Institute and involving the Greenland_cci project team and datasets, provides an integrated view of the Greenland Ice Sheet mass changes using 30 years of satellite observations.

Published in Remote Sensing in June, the paper 's key points include:

New website for Sea Ice_cci project


The Sea Ice_cci project has a new website at

The page outlines the project’s new objectives to be delivered during the current phase of the CCI programme while providing access to key project documents, product descriptions and peer-reviewed papers. 

ESA Climate Office podcast series: Views from the Void

This podcast series takes you into orbit on a tour of our planet’s climate system. You will discover different satellite technologies and get a better grasp of the observations that underlie our understanding of climate and its change. Join the ESA Climate Office as your host Anna Maria Trofaier talks to experts in satellite remote sensing about monitoring our climate system from space, and more.

Episode 1: FROZEN SEAS

Street Art exhibition to showcase role of Observing the Climate from Space

The ESA Climate Office is working with dublin-based street artist, Shane Sutton, to develop and exhibit a collection of original artworks exploring the benefits of ‘taking the pulse of our planet from space’ at the Living Planet Symposium, the world's largest Earth Observation conference, in Milan, Italy, on 13–17 May.

Staging the art exhibition during the event aims to draw the scientific community’s attention to ESA’s Climate Change Initiative and the satellite-derived climate data records it generates.

Glaciers lose 9 trillion tonnes of ice in half a century


Glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm according to an international team led by the University of Zurich in Switzerland and members of the Glaciers_cci project. 

New Arctic Ocean Altimetry review published

A new review of the altimetry methodologies used to obtain useful environmental information across the Arctic Ocean, including the effects of climate change, has been recently published in Remote Sensing with the title “Retrieving Sea Level and Freeboard in the Arctic: A Review of Current Radar Altimetry Methodologies and Future Perspectives”.
