I have had an Ambient WS1400-IP for almost 10 years, instrument package replaced once. I used to live in an area where snow was a rare event. I now live on the Kenai Peninsula in Alaska, whenever it shows, snow piles up on the instrument package case and blocks the anemometer, weather vane and the solar cell and requires going out in the snow to clean the snow off. If it happens at night you loose several hours of wind data. I would suggest that a remotely mounted anemometer and weather vane would be better in these locations. Mounting is also an issue. The unit needs to be close enough to the ground to remove the snow as well. My 2cents.
