I work for a salmon farm in Tasmania and we're about to purchase two weather stations. They will measure wind speed and wind direction and will have a digital compass to compensate for pitch and roll motion (they'll be deployed at sea). I'm dealing with Environdata (
environdata.com.au/) who have been excellent. They've spent quite a bit of time working on the motion compensating side of things. The basic model with solar panel is around $3,500 (which is all you would need if located on land), add about $1750 for a Next G modem and another $1500 for the motion compensator. They come with all their own software and will be set up so we can access the data live from out intranet. The mooring buoys we're building will cost around $6,000 ea and the units will be mounted on these 5m above sea level along with navigational lights. These units could be deployed just about anywhere.
