Weather Stations. SMI offers many versions of accurate and customized weather stations for snowmaking. SMI has developed a fast acting aspirated temperature and humidity device for automatic snowmaking and all of your resort weather needs. This unit works perfectly even after a rain event followed by a deep cold period. Conventional weather devices tend to freeze up after these weather events and do not act quickly to these changing conditions when resurfacing your slopes can be the key to your resort success.

Weather Instruments. SMI also offers weather instruments with temperature, humidity, wind speed, and wind direction along with our SmartSnow software and reporting to allow accurate and timely distribution of this information.

Weather Devices. In addition, SMI offers special and unique snowmaking weather devices such as portable and fixed solar-powered units, radio communications and hard-wired or fiber-optic communications.
