ISGTW publishes interview of W. Lengert of ESA entitled "View from above: a planet brimming with data"
ISGTW international science grid this week, interviews Wolfgang Lengert, manager of two separate Earth-observation satellite missions at ESA, about the ‘Big data from space’ event that ESA hosted in June in Frascati, Italy.
The global view provided by Earth-observation satellites — together with local data and models — helps us to better understand geophysical or human-caused phenomena. The satellite data are structured, well calibrated, and documented data assets, having the capacity to provide a reference for other data sources (e.g. (A)ATSR measuring sea-surface temperature globally within a precision level of 0.3 degrees) or to create new potential when in synergy with other data (e.g. 20 years of soil moisture data placed in context with epidemic outbreaks).
In order to exploit ‘big data’, a cloud is needed. ESA is a co-founder of ‘Helix Nebula - The Science Cloud’ and we believe that only a federated cloud can achieve the maximum contribution and participation of ‘big data’ in science.
HELIX NEBULA PARTNERSHIP
Helix Nebula is a new, pioneering partnership between leading IT providers and four of Europe’s biggest research centres, CERN, EMBL, ESA and PIC, charting a course towards sustainable cloud services for the research communities - the Science Cloud.
