Measurement of volcanic gases is critical for both public safety and understanding volcanic activity — and everything we measure relies on the wind. The USGS Hawaiian Volcano Observatory currently ...

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow ...

Atmospheric scientists have developed an algorithm that uses data from water vapor movements to measure wind. This could help predict extreme events like hurricanes. Wind speed and direction provide ...

The planet Mars has several similarities with Earth, including extinct volcanoes, dry lake beds, and active dust storms, the last of which is governed by the Red Planet’s prevailing winds. However, ...

Wind speed measurement has long been a cornerstone of meteorological observation, renewable energy assessment and aeronautical research. The performance of anemometers—devices designed to accurately ...

Have you ever wondered how an electronic wind vane translates a direction into a unique signal? It seems as though it might be very complicated, and indeed some of them are. [martinm] over at ...

Explanation: Wind vanes are used to measure wind direction. The vane points into the wind. For a more accurate reading, make arrow smaller than video shows (wanted it to be easily seen)!
