Tropospheric and stratospheric momentum flux measurements from radar wind data collected at Jicamarca
(Elsevier, 2004-02-01)
Tropospheric and stratospheric radar wind data obtained at Jicamarca, Perú (11.95S, 76.87°W) during August 17–26, 1998 have been used to estimate the momentum flux of short-period wind fluctuations together with the ...
Turbulence in the middle atmosphere: A review
(1980)
The stratosphere is characterized for being highly statically stable. lt takes considerable energy to interchange parcels of air from different altitudes; thus, turbulence is normally inhibited, Wind shears of the order ...
Mean winds in the tropical stratosphere and mesosphere during january 1993, march 1994, and august 1994
(American Geophysical Union, 1997-11-27)
Radar observations of winds and momentum fluxes in the stratosphere and mesosphere at the Jicamarca Radio Observatory in Peru ( JRO; 12S, 77W) were taken during three 10 day campaigns in January 1993, March 1994, and August ...
High-altitude-resolution stratospheric measurements with the Arecibo 2380-MHz radar
(American Geophysical Union, 1980-03)
The 2380-MHz planetary radar of the Arecibo Observatory and the 30-m interferometer antenna at Higuialles, Puerto Rico, have been instrumented. as a .bistatic radar for stratosphenc turbulence research studies. The average ...

Numerical modeling of lower stratospheric Doppler ducted gravity waves over Jicamarca, Peru
(European Geosciences Union (EGU), 2011-07)
Persistent jet structures along zonal and meridional fields, believed to be caused by stationary gravity waves, were detected in February 1999 in MST wind measurements of the troposphere and lower stratosphere over Jicamarca, ...
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 ...
A search for an association between the equatorial stratospheric QBO and solar UV irradiance
(American Geophysical Union, 2003-12)
The QBO of the zonal wind in the equatorial stratosphere between 15 and 70 hPa is analyzed in connection to the solar UV flux. F10.7 is used as a UV proxy after filtering out its long‐term variations. A running correlation ...
Spectral parameter estimation of CAT radar echoes in the presence of fading clutter
(American Geophysical Union, 1982-07)
The 430 MHz, 2 MW radar at the Arecibo Observatory is currently being used as a stratospheric-troposheric (ST) radar. One of the problems in the automatic analysis of the signals come from the very large amplitude of the ...
Mesospheric wind estimation with the Jicamarca MST radar using spectral mainlobe identification
(American Geophysical Union, 2019-12)
MST (mesosphere, stratosphere, troposphere) radar observations at Jicamarca use four antenna beams, one vertical, others tilted to the east, west, and south, to detect the scattered pulse returns from mesospheric heights ...
