4th Satellite Soil Moisture Validation and Application Workshop / CCI Soil Moisture User Workshop

18 - 20 September 2017

The Satellite Soil Moisture and Application Workshop aims to discuss and reconcile recent methodological advances in the development, validation and application of global satellite soil moisture data. The workshop series is unique by bringing together satellite users and developers to focus on both the derivation and exploration of soil moisture data from passive or active microwave satellite missions (SMAP, SMOS, ASCAT, AMRS-2, Sentinel-1, and other legacy missions). The workshop follows up former editions held at ESA/ESRIN in Frascati (Italy, 2013), in Amsterdam (Netherlands, 2014) and in New York (USA, 2016). The report from the 3rd workshop was published in the GEWEX News November 2016.


The CCI Soil Moisture User Workshop is similar in scope but particularly invites users of the CCI Soil Moisture products. Users from any relevant application area are invited to present their experiences with the data and provide ideas for future product improvements. The CCI Soil Moisture User Workshop is an event organised within the framework of ESA's Climate Change Initiative (CCI) Soil Moisture project.


Both workshops will be held at the Vienna University of Technology, on 19-20 September 2017 and on 18 September 2017, respectively.

Earth Observation Open Science Conference 2017

25 - 28 September 2017

The European Space Agency (ESA) is organising the third consultation meeting of EO Open Science in ESRIN (Frascati, Italy) from 25 to 28 September 2017 to explore new challenges and opportunities for EO research created by the rapid advances in Information and Communications Technologies (ICT). The programme includes jam and networking sessions as well as an interactive poster area.

This includes open tools and software, data-intensive science, virtual research environment, citizen science and crowdsourcing, advanced visualization, e-learning and education of the new generation of EO and Data scientists. The conference will present activities in EO Open Science and Innovation and develop a Roadmap for future ESA exploitation activities under the EO Science for society programme.


World's largest salt plain

This 100m false-colour Proba-V image, acquired on 05 April 2017, shows the salt plains on Salar de Uyuni as 'white area'.

Salar de Uyuni is the world's largest salt plain with an area of about 10,500 km2. It is located in south-western Bolivia at an altitude of 3,650 m and is extremely flat, with average elevation variations of 01 meter over the entire plains area.

The salt plains were formed 42,000 – 30,000 years ago as a result of transformations between several prehistoric lakes. The crusty top layer, which is up to several meters thick, overlays a brine rich in lithium (containing 50 – 70% of the world's reserves), potassium, and magnesium.

Small rectangular patches in the south of plains, indicate a large lithium mining area.

Northwest England

22 September 2017

Web Content Image

The Sentinel-2A satellite takes us over part of northwest England in this image captured on 05 January 2017.

The dark area near the centre of the image is the Forest of Bowland, appearing mostly brown because this image was captured during the winter when there were no leaves on the trees. The area also has barren fells and peat moorland. During the Second World War, parts of the Bowland fells were used for military exercises, and unexploded bombs have been found in the area.

In the upper left we can see some of the intertidal mudflats of Morecambe Bay, with the city of Lancaster on the coast. The city of Preston is situated at lower left on the River Ribble, which flows into an estuary where it meets the Irish Sea.
