Differences in near-mesopause summer winds, temperatures, and water vapor at nothern and southern latitudes as possible causal factors for inter-hemispheric PMSE differences
(American Geophysical Union, 1999-06-01)
We report the results of a recent study to examine possible causal factors that could explain the observed differences in PMSE intensity in the northern and southern hemispheres. A variety of satellite data, models and ...
PMSE strength during enhanced D region electron densities: Faraday rotation and absorption effects at VHF frequencies
(Elsevier, 2014-10)
In this paper we study the effects of absorption and Faraday rotation on measurements of polar mesosphere summer echoes (PMSE). We found that such effects can produce significant reduction of signal-to-noise ratio (SNR) ...
Inter-hemispheric differences in PMSE: are they due to differences in mesopause temperatures?
(1995)
Recent observations using the Peruvian\U.S. Profiler at Machu Picchu Base in Antarctica show that PMSE are vastly weaker in the southern hemisphere relative to the north. The difference in average echo strength in the two ...
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, ...
Polar mesosphere summer echo studies at 51.5 MHz at Resolute Bay, Canada: Comparison with Poker Flat results
(American Geophysical Union, 2001-11)
We present a study of seasonal and diurna! variations of polar mesosphere summer echoes (PMSE), along with temperature and wind data collected during summer 1998 using the 51.5 MHz VHF radar located in Resolute Bay, Canada ...
First observations of PMSE in Antártica
(Ciências espaciais e da atmosfera na Antártica, Transtec Editorial, 1995)
A 50 Mhz radar, with 25 kW average power, has been installed at the Peruvian base in St. George lsland, Antarcitc. A search far PMSE echoes were made during its first year of operatlon, with negative results. These resutts ...
First observations of polar mesosphere summer echoes in Antarctica
(American Geophysical Union, 1999-10-01)
A 25‐kW peak power 50‐MHz radar was installed at the Peruvian base on King George Island, Antarctica (62°S), in early 1993. A search for polar mesospheric summer echoes (PMSEs) was made during late January and early February ...
Average vertical and zonal F region plasma drifts over Jicamarca
(American Geophysical Union, 1991-08)
The seasonal averages of the equatorial F region vertical and zonal plasma drifts are determined using extensive incoherent scatter radar observations from Jicamarca during 1968–1988. The late afternoon and nighttime ...
Tropopause altitude and PMSE detection at 78°N, 16°E, 2008: first results of the refurbished SOUSY Svalbard Radar (SSR2)
(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.
Polar mesospheric summer echoes at 78°N, 16°E, 2008: First results of the refurbished sounding system (SOUSY) Svalbard radar
(American Geophysical Union, 2009-06-06)
This paper examines in detail the electrical coupling between the high-, middle-, and low-latitude ionospheres during January 17–19, 1984, using interplanetary and high-latitude magnetic field data together with F region ...
