ESA's biggest scientific symposium gets underway 
More than 1200 scientists from around the world have gathered in Bergen, Norway, for ESA’s week-long Living Planet Symposium to present their latest findings on Earth's environment and climate using data from observation satellites. Addressing the participants, the Norwegian Minister of Trade and Industry Trond Giske underscored the importance of Earth observation saying that it is a priority for the Norwegian government and that space should be useful for society.
The symposium was formally opened by ESA’s Director of Earth Observation programmes, Volker Liebig. He stressed the importance of the programme, saying that ESA satellite archives, dating back to 1991, have delivered valuable data about our planet, increased our knowledge of Earth and improved our confidence in climate change predictions.
He commended the scientists at the symposium for using these data to identify and analyse long-term climatic trends and changes.
"ESA is responding to the ever-growing demand for Earth observation data with new missions and simplified access to our data archives," said Prof. Liebig.
In this context, he announced that the new ESA Data Policy has been ratified, which guarantees free and open access to the majority of data from the Agency's missions.
While the unveiling of these new datasets will be a highlight of the week, so will the continuing achievements of ESA's ERS and, in particular, Envisat satellites. Dr Johnny Johannessen of Norway’s Nansen Environmental and Remote Sensing Center provided an overview of ERS and Envisat.
"Twenty years of regular monitoring with ERS-1, ERS-2 and Envisat has provided an excellent and powerful satellite database for multidisciplinary studies of the Earth system, including the ocean, cryosphere, atmosphere, land, biosphere and the solid Earth," Dr Johannessen said.
The symposium promises to be an exciting and informative week, with in-depth sessions devoted to new aspects of observing Earth from space. For example, ESA's Climate Change Initiative, which aims to build long-term datasets of 'Essential Climate Variables' to help predict future climate change, will be presented.
The symposium will also highlight progress made in the Global Monitoring for Environment and Security initiative and the families of Sentinel missions that ESA is developing specifically for the programme.
