RISVertical Motions in the Upper Middle Atmosphere from the Saskatoon (52°N, 107°W) M.F. Radar
Publisher: American Meteorological Society
Abstract: The Saskatoon M.F. radar (52°N, 107°W) was operated in a Doppler mode to measure the vertical motions in the middle atmosphere (60?110 km). The 5-min and 1-h mean velocities were accumulated for a full calendar year. Mean ...
Gravity Wave Propagation Characteristics (60–120 km) as Determined by the Saskatoon MF Radar (Gravnet) System: 1983–85 at 52°N, 107°W
Publisher: American Meteorological Society
Abstract: Gravity waves (GW) have been detected and their characteristics measured by observations with the Saskatoon multiple bistatic system, Gravnet. Data are available from 50 days for two height ranges 64?97 km, ?100?115 km, ...
Small-Scale Features in the Middle Atmosphere Wind Field at Saskatoon, Canada(52°N, 107°W): An Analysis of MF Radar Data with Rocket Comparisons
Publisher: American Meteorological Society
Abstract: The wind field of the middle atmosphere (60-100 kin) is sampled by the Saskatoon Medium Frequency radar: temporal resolution is normally 5 rain, and vertical is 1.5/3 kin. Profiles are analyzed for gravity waves (GW), and ...
The Dynamics of the Mesosphere and Lower Thermosphere at Saskatoon (52°N)
Publisher: American Meteorological Society
Abstract: The dynamics of the upper Middle Atmosphere (60?110 km) over Saskatoon (52°N, 107°W) are described, using wind data from a medium frequency radar (2.2 MHz). Seasonal variations of gravity wave intensities (8 h-10 min) and ...
Internal Gravity Waves in the Mesosphere and Lower Thermosphere at Mid-Latitudes
Publisher: American Meteorological Society
Abstract: Wind data from approximately 75?110 km for the years 1972?75 have been obtained by the radiowave partial reflection drift technique. A summary of data which have appeared in earlier papers, and which relate to internal ...
Lunar Tidal Winds Measured in the Upper Atmosphere (78–105 km) at Saskatoon, Canada
Publisher: American Meteorological Society
Abstract: Six years of winds data measured by the partial reflection drifts technique have been analyzed for lunar tides. Data are available at 3 km intervals of height and are separately analyzed in two year datasets to cheek ...
The Semi-Diurnal Tide at the Equinoxes: MF Radar Observations for 1978–1982 at Saskatoon (52°N, 107°W)
Publisher: American Meteorological Society
Abstract: Observations of the semi-diurnal atmospheric tide have been made on a continuous daily basis since September 1978 by a medium frequency (MF) radar. The monthly mean zonal winds and tidal amplitudes and phases (70?110 km), ...
Developments in the Radiowave Drifts Technique for Measurement of High-Altitude Winds
Publisher: American Meteorological Society
Abstract: The drifts technique derives wind vectors from correlation analysis of spatial and temporal sequences of radiowave field strength at ground level. The paper examines the bases of the analysis, and presents a new method ...
Winds and Wave Motions to 110 km at Mid-Latitudes. V. An Analysis of Data from September 1974–April 1975
Publisher: American Meteorological Society
Abstract: The behavior of the daily noon winds at 52°N, 107° W (Saskatoon, Canada) at altitudes from 52 km to about 110 km are studied for the interval September 1974?Apzil 1975. These data are compared with ROCOB temperatures and ...
Winds and Wave Motions to 110 km at Midlatitudes. VI. Tidal, Gravity and Planetary Waves, 1976
Publisher: American Meteorological Society
Abstract: The results of partial reflection radiowave wind observations (60-110 km) for four 10-day intervals in 1976 at Saskatoon, Canada (52°N, 107°W), are presented. A harmonic analysis has been applied to data for the four ...
