A wind profiler is a type of weather observing equipment that uses radar or sound waves (SODAR) to detect the wind speed and direction at various elevations above the ground. Readings are made at each kilometer above sea level, up to the extent of the troposphere (i.e., between 8 and 17 km above mean sea level).

Wind profilers are Doppler radars that most often operate in the VHF (30-300 MHz) or UHF (300-1000 MHz) frequency bands. There are three primary types of radar wind profilers in operation in the U.S. today.

Wind profilers are Doppler radars that transmit vertical electromagnetic pulses, which bounce off atmospheric conditions, such as clouds, precipitation, and turbulence to provide information about wind speed and direction at various heights in the atmosphere.

The radar wind profiler (RWP) is an active remote-sensing instrument that can routinely, and virtually unattended, observe wind and turbulence in the troposphere through scattering from clear -air irregularities

Radar wind profilers (RWPs) are meteorological radars that are used to determine the vertical profile of the wind vector in the atmosphere. RWPs typically use wavelengths ranging from about 20 cm to about 6 m.

2024年5月29日 · Wind profiler radars are sophisticated devices used in meteorology to measure the wind speed and direction at various altitudes above the ground. Unlike traditional weather balloons, which provide data for a specific location at specific times, wind profiler radars offer continuous, real-time wind measurements.

Wind profilers measure wind speed and direction in a vertical column above the wind profiler antenna. They are sometimes referred to as "virtual meteorological towers". The operation principle of a wind profiler is based on the scattering of waves at inhomogeneities in the air.

We have three 915 MHz profilers and one 1290 MHz profiler. These are standard LAP3000 boundary layer wind profilers commonly used for lower atmospheric research and monitoring, and have been deployed at over 50 field projects since 1992.

The 449 MHz modular wind profiler developed out of the MAPR (Multiple Antenna Profiler Radar) system, and is capable of making rapid, high resolution measurements of the wind profile of the lower atmosphere. Spaced antenna techniques are used to make rapid wind measurements, enabling a wind profile to be made on time scales of 1 - 5 minutes, as ...
