- 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.

- Access is made via TELNET to espsun.space.swri.edu using
- port 10000. One may also request a private account if
- extensive use is projected. NASA sponsored investigators may
- access this system through the NASA Master Directory on host
- nssdca.gsfc.nasa.gov. X-window system servers are supported
- for graphical displays.

- A detailed list of the data holdings may be requested from
- sddas-help@swri.edu. The database server is a SUN
- SPARCserver 330, soon to be upgraded with additional CPUs.
- The SDDAS software is available to qualified users for
- installation on their own workstations. Immediate plans
- involve the addition to the archive of particle and field
- measurements from the Upper Atmosphere Research Satellite.
