Overview
The Lufft family of multi-parameter weather sensors offer a cost-effective, compact alternative for the acquisition of a variety of measurement parameters on land- and buoy-based weather stations. Depending on the model, each sensor will measure a different combination of weather parameters to meet a wide variety of applications.
Wind Speed & Direction
The wind sensor uses four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.
Compass
The integrated electronic compass can be used to check the north-south adjustment of the sensor housing for wind direction measurement. It is also used to calculate the compass-corrected wind direction.

Lufft WS-Series Weather Stations: A history of weather monitoring translates to high quality weather sensing options
Gotthilf Lufft started building mechanical weather sensors in 1881. “They really began by measuring temperature and humidity in the most basic sense,” said Ann Pattison, Lufft USA product manager. More than 130 years later, the company is still building weather monitoring technology. For their most recent rendition of weather stations, Lufft engineers traded mechanical dials and horse hair for ultrasonic transducers and pyrometers to create a line of electronic all-in-one weather stations called the WS-Series. The systems have a modular formula that can be tailored to customer’s applications. In fact, many of the ready-made combinations Lufft offers, like a weather station with built-in tipping bucket rain gauge, were inspired by customers.

NASA develops ocean surface wind speed measurements through GPS
Researchers from the NASA Langley Research Center in Hampton, Va., have discovered that GPS signals can be used to accurately measure wind speed at the ocean’s surface, National Geographic has reported. Researchers have concluded that by measuring the distortion in GPS signals bouncing off the ocean’s waves, they can successfully measure wind speed, even in the case of hurricanes and extreme weather. To measure the accuracy of using GPS for wind measurements, NASA scientists placed GPS receivers on NOAA research planes. They concluded that GPS data has an accuracy capable of detecting wind speeds within 11 miles per hour.

Delaware Environmental Observing System detects rare tornado in state
A University of Delaware monitoring network picked up a tornado that touched down in Newark on June 10, according to a release. Tornadoes are rare in the state, but sensors were there to capture it. The Delaware Environmental Observing System, which supplies data to the National Weather Service, charted the tornado with winds of 65 to 85 mph. The observing system also measured the heavy rain that accompanied the tornado. Experts say a low-pressure system and cold front in the Ohio Valley met with warm air in Delaware, which set off the churning clouds that ultimately generated the tornado. The tornado was picked up by a weather station nearly a half mile away, which measured wind speeds at 20 mph.
