Prevailing Mesosphere Wind Estimates (Meteor Winds) from the MAP/WINE Experiment at Volgograd, USSR and Heiss Island (Arctic Ocean)Entry ID: MAPDA-PMW034
Abstract: This data set contains wind estimates for both the zonal and meridional
components of prevailing winds recorded at Volgograd, USSR and Heiss Island
(Arctic Ocean). The measurements were carried out under the MAP/WINE Project
using ground-based meteor radars. The derived prevailing wind is not
climatological as it varies from day to day.
The term 'meteor wind' is used for the mesosphere wind ... estimates derived from
meteor trail drifts measurements. Ionized meteor trails are produced by
meteoroids (meteor particles) which enter the Earth's atmosphere. A meteor
trail moves in the atmosphere due to the neutral wind and magnetic field.
The radial component of this movement is measured using meteor radar. Estimates
of 'meteor wind' are derived for each direction (North, South, East, West) from
the set of measurements of radial components using statistical characteristics
of meteor parameter distributions and parameters of antenna pattern. Meteoroids
occur in the height interval 80-100 km and are centered at 92-95 km (maximum
for the apex time, near 6 a.m. LT, and minimum for anti-apex time, near 6 p.m.
The MAP/WINE (Middle Atmosphere Program/Winter in Northern Europe) was one of
the MAP projects scheduled for Fall-Winter 1983-1984. The aim was to coordinate
observational studies of the high-latitude European middle atmosphere in
winter, leading to an improved understanding of the winter variability
structure, motions, and composition.
