Mining and exploiting the NASA Solar Dynamics Observatory data in Europe
The Dream Team
Meeting pages
Purpose
The NASA SDO (Solar Dynamics Observatory) space mission is extraordinary in many ways. Its three solar instruments, AIA, HMI and EVE, push the technology and in particular the production rate of data to extreme values. For example, the SDO-AIA telescope built by LMSAL will produce by the end of 2009 a 4k x 4k image every five seconds for each of it four telescopes (10 spectral bands). Such performance is eminently justified on the scientific level, and SDO will enable many discoveries in our field. However, at about two TB per day of data, old ways of looking at the data will not be practical anymore. Mining SDO data, representing them meaningfully, and creating useful metadata require automatic tools based sometimes on advanced mathematical techniques.
Our International Team spans a wide range of expertise in the development of software for the pre-processing or post-processing of solar data. The purpose of this International Team will be to compare different algorithms having a same purpose, to discuss the desired outputs and their operational implementation in data centers. We will also seek how to combine different algorithms in order to enlarge their scope and potentially define new meaningful representation. Finally, we will study solar eruptions and the possibility to have early prediciton. This subject has impacts both on Space Weather applications, as well as on the understanding of the physics underlying solar eruptions.

Subsistence
Since good work needs some good food, here are some suggestions from another ISSI team to get some subsistence in the evening
