[2700] Magnetospheric Physics
Scientific paper
There is a large number of data archives for magnetospheric physics that, however, usually provide access only to spin-averaged datasets. In addition only limited resources have been used to calibrate the measurements to a level that the users could easily analyze them with no need to worry about the quality of the data. These are the starting points to the ESA Cluster Active Archive (CAA, see URL: http://caa.estec.esa.int) that provides access to the calibrated full-resolution datasets of the four-satellite Cluster mission. The data archive is publicly accessible and suitable for science use and publication by the world-wide scientific community. This presentation will focus on the usability aspects of the overall system and its services and the quality of its datasets. The Cluster mission has collected observations for nine years since 2001 and has now submitted a proposal for further observations during years 2010-12. The CAA will contain the entire set of Cluster high-resolution data and other allied products in a standard format and with a complete set of metadata in machine readable format. The data can be accessed either via web GUI or via command line wget tool. Currently there are more than 200 datasets from each spacecraft, including high-resolution magnetic and electric DC and AC fields; full 3-dimensional electron and ion distribution functions and moments from a few eV to hundreds of keV; and various ancillary and browse products to help with spacecraft and event location. To ensure the high quality of its datasets, the CAA runs a series of cross-calibration workshops that focus on detailed comparisons of the measurements. Currently the observations from years 2001-7 are available for most instruments. The total amount of data files in compressed format is expected to exceed 50 TB. The CAA became operational in February 2006 and now has more than 900 registered users who download about 100-1000 GB of data every month. The CAA provides user-friendly services for searching and accessing these data products as well as for visualizing some of the scientific parameters. The CAA is continuously being upgraded in terms of datasets and services.
