HAARP Like Facility +40° 10' 54", -104° 43' 30" ...
The Platteville Atmospheric Observatory was envisioned in 1962 by what is now the Institute of Telecommunication Sciences (ITS), a part of the National Telecommunications and Information Administration (NTIA), as a site for high-powered radio experiments. While the initial experiment, that took place in 1968, studied over-the-horizon radar, the majority of later experiments used high power radio waves to modify the ionosphere in a process that is sometimes called ionospheric heating because it raises the electron temperature in the ionosphere. The ionospheric heater was still used until 1984, when the last ionospheric experiments were performed. In the same year, the transmitters were loaned to the Office of Naval Research and sent to HIPAS in Alaska where they are still used. With the removal of the transmitters, the focus of
the facility changed to smaller-powered observation of the atmosphere rather
than modifying it. In 1988 the 404 MHz RASS was installed and the ownership
of the facility was transferred from NTIA to NOAA-ERL.

The Platteville Atmospheric Observatory was one of
the first major ionospheric heaters in the world. Operating from 1968 through
1984, it expanded knowledge of ionospheric processes greatly. The observatory
continues operation, but now focuses on wind profiling. The first studies
were made of HF heater induced airglow, heater-induced
spread F, wide band heater-induced absorption, and heater created field-aligned
ionization.
Wind measurements of MLT region
using the Platteville,
Abstract: Meteoroids enter the earth’s atmosphere constantly,
producing a trail of ions due to their interaction with the air
molecules. Using radar techniques, these trails are
detected and used as tracers of the atmospheric winds by measuring the
Doppler shift of the return echo as the trails drift with the wind. We
present initial results of the atmospheric wind estimates in the mesosphere/lower
thermosphere (MLT) region measured using an improved Meteor Echo Detection
and Collection (MEDAC) system. For the data presented in this work, the
MEDAC is operated with an all-sky 50MHz radar system at the Platteville
Atmospheric Observatory, located at 401N, 1051W. A five receiver interferometer
is used to detect and estimate the precise location of the trail. Further
processing yields mean wind estimations for the height range in between
80 and 110 km. Spectral analysis show strong diurnal and semidiurnal oscillations
for the resulting wind estimates.

Since its founding in 1966, the Platteville Atmospheric
Observatory has been at the forefront of atmospheric science. The observatory's purpose
has broadened beyond its original use for ionospheric heating, by housing instruments including wind profilers, a
MF radar, meteor radars, and hydrology instrumentation.
In 1997, a Major Research Instrument
Grant was awarded by the NSF, which has facilitated major upgrades,

NOAA Boulder Atmospheric Observatory (BAO) Boulder, Colorado +40° 02' 59.64", -105° 00' 12.71" ...
Earth System Research Laboratory
For more details contact Dan Wolfe, 303-497-6204 Completed in 1977, the BAO is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The centerpiece of the facility is a 300-m tower instrumented at five levels with slow-response temperature and wind sensors, a variety of remote sensing systems, and a real-time processing and display capability that greatly reduces analysis time for scientists. The BAO has been the host of several large national and international experiments and numerous smaller ones. SOURCE: http://www.esrl.noaa.gov/psd/technology/bao/
