Volcanic belt of the Andes

Proba-V spotted a lovely patchwork of volcanic fields with several calderas and lava flows (visible in black), alternating with salt deserts and salt lagunes (visible in white) on the border of Chile and Argentina in the southern volcanic zone of the Andes, at altitudes ranging between 03 and 6.5 kilometres above sea level, in this 100m false-colour image from 05 April 2017.

The salt desert of Antofalla is also clearly visible in this image as narrow and elongated white terrain. It is the longest salt desert in the world. This desert is accompanied by the namesake volcano (6,400 m) to its northwest. In the northwest corner, is the Lago Salar del Hombre Muerto (salt lake of the dead man), a name that testifies to the harsh, dry and cold environment of this remote area. It is mainly famous for tourism and scientific expeditions.

Despite the aridity (less than 200 mm precipitation annually), there are some green pastures and small lakes (Lagunas), shown here in bright blue, that support, for instance, Andean wildlife such as flamingos, foxes or vicuñas.

Call for abstracts - Radar Altimetry Symposium 2018

17 January 2018

Following on from the 15 Years and 20 Years of Progress in Radar Altimetry Symposia in 2006 and 2012, both deemed very successful landmarks by the participants and the readership of the Proceedings, we have now reached the 25-year anniversary of the first supply of ERS-1 and TOPEX/Poseidon data products to the Altimetry Community.

To mark the occasion, the European Space Agency (ESA) in collaboration with the French Space Agency (CNES) is organising an exceptional Symposium on "25 years of Progress in Radar Altimetry".

Abstract submission is now open. You are kindly invited to submit your abstract by 01 March 2018.

The event will take place in Ponta Delgada, São Miguel Island, Azores Archipelago (Portugal) from 24 to 29 September 2018.

Along with the symposium, related events will take place in the same week which includes the annual meeting of the Ocean Surface Topography Science Team (OSTST) and the International DORIS Service (IDS) Workshop.
