Radar-measurements in the Tropo, Strato and Mesosphere
(Max-Plank Institute für Aeronomie, 1976-07)
An experiment was performed using the large 50 MHz-radar at Jicamarca/ Peru to obs erve waves, winds and clear air turbulence (CAT) at tropospheric and stratospheric heights. The antenna was used asan interferometer in ...
Radar calibration of mesospheric and ionospheric echoes based on the incoherent scatter and magneto-ionic propagation theories (MST-ISR 2 campaign)
(Instituto Geofísico del Perú, 2010)
Diapositivas presentadas en el II Encuentro Nacional de Radio Científicos e Investigadores Afines 2010 (URSI- PERÚ), llevado a cabo en la Pontificia Universidad Católica del Perú.
Calibrated radar observations of the equatorial mesosphere and ionosphere during an 11-day campaign
(Instituto Geofísico del Perú, 2009)
Presentado en MST12 - 12th Workshop on Technical and Scientific Aspects of MST Radars, London, Ontario, Canada, 17-23 May 2009.
Radar observations of winds and turbulence in the stratosphere and mesosphere
(American Meteorological Society, 1974-03)
A technique for the observation of radar echoes from stratospheric and mesospheric heights has been developed at the Jicamarca Radio Observatory. Signals are detected at the altitude ranges between 10–35 km and from 55–85 ...
Turbulent kinetic energy dissipation rate and eddy diffusivity study in the tropical mesosphere using Jicamarca radar data
(Clemson University, 2006-05)
The MST radar at Jicamarca Radar Observatory JRO is a powerful radar that can detect atmospheric turbulence on the Bragg scale of 3 m in the daytime mesosphere 60-85 km Since 2002 the radar was operated for a few days each ...
Southern-hemisphere PMSE: Where are they?
(American Geophysical Union, 1993-09)
We report a surprising absence of PMSE (Polar Mesospheric Summer Echoes) in VHF radar observations of the southern summer high-latitude mesosphere. Our observations cover about twenty days during January-February, 1993, ...
Dynamics of the equatorial mesosphere observed using the Jicamarca MST radar during June and August 1987
(American Meteorological Society, 1992-12)
The Jicamarca MST radar was used in two campaigns during June and August 1987 to measure wave influences, flow variability, and mean structure in the equatorial stratosphere and mesosphere. This paper presents observations ...
High-resolution observations of mesospheric layers with the Jicamarca VHF Radar
(Elsevier, 2007)
We report new results from the 50-MHz Jicamarca radar in Peru (12°S, 77°W), which is able to observe backscatter from the daytime mesosphere on any given day. Since 2005, the radar has been operated in a high-power MST-ISR ...
Mesospheric winds and waves over Jicamarca on May 23-24,1974
(American Geophysical Union, 1979-08-01)
The VHF radar at Jicamarca (12.0°S, 76.9°W) was used to probe the mesosphere for 24 hours on May 23–24, 1974. The inferred zonal wind shows a strong eastward prevailing component below 75 km for these winter conditions, ...
A cooperative synchronous observation of winds and tides in the tropical lower stratosphere and mesosphere using VHF radars at Jicamarca and Arecibo
(Society of Geomagnetism and Earth, Planetary and Space Sciences, 1986-04)
A cooperative synchronous observation of winds in the tropical lower stratosphere and mesosphere was carried out using VHF radars at Jicamarca (11.95°S, 76.87°W) and at Arecibo (18.35°N, 66.75°W) on 19-21 or 23 November ...
