FPS Sites for TIMED
Mark Conde
(mark.conde@gi.alaska.edu)
of the University of Alaska is responsible for the analysis of
the Fabry-Perot instruments located at:
- Poker Flat, Alaska (65.12N, 212.57E, 65.4mlat)
-
Inuvik, Canada (68.33N, 133.50W, 71.25mlat)
These are both fixed-gap imaging Fabry-Perot Spectrometers (FPSs)
that use a CCD imager for light collection. The Inuvik instrument
has a narrow field of view and looks in the vertical so the output
are neutral vertical winds and neutral temperatures. The filter
used prior to November 2001 was for the red line around 240 km,
and the data are in the CEDAR Database. After November 2001,
a green line filter was installed to look at emissions from around
96 km. The Poker FLat instrument has an all-sky camera lens on
the front so it is able to get the temperature and velocity from
47 separate zone locations in the sky. Vertical winds are available
above the station, while meridional and zonal winds are found in
circular zone areas around the zenith. The present filter is
for red line emissions around 240 km, but a green line filter
is on order and will be used part of the time for observations
around 96 km.
Other regular scanning Fabry-Perot Interferometers (FPIs) would be happy
to provide data for CEDAR/TIMED (*'d), and many contain data in the
CEDAR Database along with contact information.
