cops_supv_mfuhfw_wprolo_d: wind profil taken by Meteo-France UHF in low mode at station Niederrott

Dataset
Summary
The period of permanent measurement was : 1st July - 31 July 2007.
The measured parameters are : height, eastward and northward wind, upward air velocity,wind speed and direction, signal to noise ratio.
The operation was continuous, with a daily check.

The measurements were taken near the village of Meistratzheim, 20 km south_westward of Strasbourg.
The platform on the site of Niederrott is installed just between 2 types of vegetation : Maize on the west and short grass on the east part.

The UHF wind profiler is composed of five beams, one pointing vertically and others, with a zenital angle of 17° and orientated along the West, East, North and South.
The wind component along each beam direction is deduced from the Doppler shift of the backscattered signal. The three wind component (N, E and vertical) are thus deduced from the redundant five radial velocities, with the assumption that the horizontal gradient of the wind is weak in the volume scanned by the radar.
The range of altitudes covered by the instrument is variable, depending on atmospheric conditions and electronic parameters. The time resolution of the profilers is 6 mn.

In low mode (as in this entry) , the profile of the horizontal wind is valid between 75 and 6300m with a resolution of 150m and 75m between each gate.

In high mode (as in entry cops_supv_mfuhfw_wprohi_d) , the profile of the horizontal wind is valid between 150 and 13500m with a resolution of 350m and 150m between each gate.
