           The SDDAS maintains a large optical disk  database  of  data
           returned  by the Dynamics Explorer satellites 1 & 2. It pro-
           vides interactive tools for displaying this data in  various
           ways and selected subsets may be acquired via anonymous FTP.
           This data is primarily used by those doing research in space
           physics,  magnetospheric  physics,  and  the dynamics of the
           upper atmosphere. The measurements are  classified  as  fol-
           lows: DC magnetic field; AC electric field; particles; elec-
           tron and ion ionospheric temperature and density; ion compo-
           sition  and  drift; thermal neutral drift, composition, den-
           sity, and temperature.
