The High Latitude Monitoring Station
The High Latitude Monitoring Station (HLMS) is located on the outskirts of
Elmendorf Air Force Base near Anchorage, Alaska. HLMS was established
in 1950 by the Department of Commerce; today, it
is operated by the Geophysical Institute, with one technician on the site.
HLMS instruments are connected to the Geophysical Institute by leased
data lines.
The primary mission of HLMS has been to monitor the earth's ionospheric
environment, and to collect and reduce raw geophysical data (including
seismological information) for analysis and archiving at the Geophysical
Institute and other organizations nationwide.
HLMS supports the following instrumentation for ionospheric research:
- VHF auroral radar, which
monitors reflections from ionospheric structures in the E-region between
Poker Flat and Kaktovik.
- Magnetometer and riometer,
providing information about geomagnetic and solar flare effects as
part of the Remote Geophysical Operational Network (RGON).
- Total Electron Content (TEC) measuring equipment which monitors the
density of plasma in the ionosphere overhead.
