High resolution Atmospheric Pressure
J. E. Tillman and Neal C. Johnson
This instrument is located at the Department of Atmospheric
Sciences, University of Washington, Seattle Washington. It is approximately
33.5 meters (110 feet) above mean sea level. In typical atmospheric conditions
this sensor reads approximately 4 millibars lower than it would at MSL.
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. Johnson and Fred Weller, UW, developed and maintain the system and
software.
