TIMED-CEDAR Workshop Monday 17 June 2002 Front Range Theatre 01:00-03:00 pm

Kind of Workshop: Campaign planning, preliminary science results

Type of Workshop: Some invited talks followed brief limited talks with lots of discussion.

The NASA Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) satellite was successfully launched December 7, 2001. The overall TIMED mission also includes numerous NSF/CEDAR ground-based collaborative partners. TIMED studies the temporal and spatial variations of the basic atmospheric structure and energy balance between 60 and 180 kilometers. This workshop will be dedicated to planning collaborations between groundbased and satellite observational teams with an emphasis on validation studies, as well as presentation of preliminary scientific results. There will be short oral presentations on the status of the mission and instruments.

We would like to invite all interested to participate in the discussions afterward. For those of you who would like to make short presentations on your planned collaborations and/or scienitific results please contact Dr. Sam Yee (240-228-6206).

The TIMED instruments include: GUVI, a spatial scanning far ultraviolet spectrograph that measures composition and temperature in the lower thermosphere, as well as auroral energy inputs; SABER, an infrared radiometer, measures pressure, temperature, and infrared cooling rates in the stratosphere, mesosphere, and lower thermosphere; SEE, a spectrometer and a suite of photometers, measures incoming solar irradiance; and TIDI, a Fabry-Perot interferometer, measures horizontal vector winds, temperature, and composition in the mesosphere and lower thermosphere. We also have numerous groundbased NSF/CEDAR partners conducting joint TIMED/CEDAR studies.
