The CDPP data base: a tool for the EISCAT community

International audienceThe CDPP (Centre de Données de la Physique des Plasmas – http://cdpp.cesr.fr) is a data centre serving the space plasma physics community. Its primary purpose is to preserve data relevant to the physics of naturally occurring plasmas, especially data from experiments which are either French or have strong French participation; the CDPP both renders this data accessible, and facilitates its exploitation. The datasets available at CDPP include data from space missions since 1978 and from EISCAT KST observations since 1984, and ESR observations as well. We will overview the status of the archive, including the EISCAT data archived in the Grenoble EISCAT database (http://www-eiscat.ujf-grenoble.fr), which is associated to the CDPP. Recently new tools were developed: they include a coordinate transformation library for Solar-Terrestrial studies and Custom-made plots, a new feature that allows the user to plot data that he has ordered. We will show how the EISCAT community could gain a large benefit in using the facilities provided by CDPP
