Sentence examples for medium frequency radar from inspiring English sources

Buckland Park medium frequency radar.

The difference between meteor radar and medium frequency radar winds is larger during winter than during summer, which might indicate an indirect influence of gravity waves on spaced antenna measurements.

At both sites, the medium-frequency radar winds are clearly underestimated, and the underestimation increases from 80 km to the maximum height of 98 km.

Rao et al. ([2012]) analyzed approximately 80 to 100 km altitude winds at low latitudes based on measurements of four medium-frequency radars and three meteor radars.

The IUGONET metadata database is already used outside the IUGONET institute, for example, as a metadata management system of the imager and medium frequency (MF) radar of National Institute of Information and Communications Technology.

For example, a study of the 2-day waves in mesospheric zonal and meridional winds by medium frequency (MF) radar over Adelaide by Harris (1994) showed their occurrences for 2- to 3-week duration generally following mid-summer.

Meteor wind data from Cariri and Cachoeira Paulista (Brazil) and medium frequency (MF) radar wind data from Tirunelveli (India) are analyzed together with Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics/Sounding of the Atmosphere using Broadband Emission Radiometry (TIMED/SABER) temperature in the 40- to 100-km region to characterize the zonal and vertical propagations of these waves.

Since the meridional wind variation observed by a medium frequency (MF) radar at Rothera Station showed a very good correlation with the temperature variation during this period, these researchers concluded that the temperature variation was caused by an enhancement of the inter-hemispheric meridional flow from summer (north) to winter hemisphere (south).

Sridharan et al. ([2010]) examined the long-term variations in the mean wind and tidal wave amplitude in the mesosphere and lower thermosphere using the wind data obtained from the medium-frequency (MF) radar at Tirunelveli near the equatorial region.

Then, a mechanism to explain this single NLC event is suggested by comparing the atmospheric parameters of the upper mesosphere provided by satellites (AURA and AIM) and medium-frequency (MF) radar in "Discussion" section.

The ISO was first observed by Eckermann and Vincent ([1994]) in the mesosphere and lower thermosphere (MLT) zonal wind in the period range 10 to 100 days with dominant periodicities in the bands approximately 60, 35 to 40, 20 to 25 days using medium-frequency (MF) radar at Christmas Island (2°N, 157°W).
