GAIA is a virtual observatory providing quick access to summary data from satellite and ground-based instruments that remote sense auroral precipitation. Data from riometers, All-Sky Imagers (ASIs), Meridian Scanning Photometers (MSPs), and satellite-based global imagers are included in GAIA. GAIA is the virtual observatory for Gloria
and the Auroral Optical Network
, both of which are elements of the IPY
intiative. GAIA is an international effort being carried out by groups in (at present) Canada, Finland, Sweden, the UK, the US, and Japan. GAIA involves a user interface that will support browsing of summary data, retrieval of summary and full-resolution data, and some synoptic analysis of those data. GAIA has at its core a relational data base, and various scripts that interact with the user interface, the data base, and data providers. To facilitate reliability, GAIA will develop at least two and likely three mirrort sites (one in Fimland, one in the UK, and possibly one in Asia). In the future, the GAIA Legacy Project will undertake to recover and make accessible older data sets from instruments on (for example) ISIS-II, Freja, Viking, as well as various ground-based programs.
