This instrument is located at the Department of Atmospheric Sciences, University of Washington, Seattle Washington. The primary sensor, developed by Vaisala Oy, Helsinki, Finland, is identical to that used for the Russian Mars 96 Program; their program includes European & US collaboration. We gratefully acknowledge Risto Pellinen and Ari-Matti Harri, Finnish Space Science Institute, for providing the sensor and Pekka Jarvi of Vaisala Oy, Helsinki, Finland , for integrating it into a commercial instrument and calibrating it for us. Support was provided by NASA Headquarters ( Planetary Instruments Program ) and Jet Propulsion Laboratory. James E. Tillman, Neal C.
