Measuring wind speed is not too difficult. A few Legg's Eggs, straightend out coathanger or bicycle wheel spokes and a capstan motor connected to a d'Arsonval panel meter calibrated with a vehicle speedo on a lazy summer afternoon. Presto +/- 3 mph (0-100) accuracy without Vaisala price. That's cool.
Of course when you need accurate wind measurements over the ocean and you're moving things become difficult.
The instrument tower houses the US Aneomometer along with an array of capacitive humidity sensors, RTD sensors, PVC for insolation capture and a Trimble GPS interface to record motion. The aneomometer is solid state with no moving elements and can determine wind flow volumetrically or in absolute velocity along with prevailing direction. Next year one will be sitting out a hurricane recording ~1200 readings/sec to provide data that's never been seen before.
Gone are the simple days. Pressure, temperature, and humidity are monitored and fed into the computer to assist with calculations to determine how fast the natural wind is moving over the surface of the sea.
Anyhow, that's one of the projects we've been working on and I figured it was worth discussing on a tech forum.
