Anemometer: Used to measure wind speed.
Barometer: Measures atmospheric pressure. Used to find high pressure systems and fronts.
Doppler Radar: Specialized radar system that uses Doppler effect to produce velocity data.
Hygrometer: Measures the amount of water in the air, humidity.
Ice Core: Sample removed from an ice sheet. Most commonly from the polar ice caps of Antarctica.
Rain Gauge: Gathers and measures the amount of liquid precipitation over a set period of time.
Orbiting Satellite: Helps in creating forecasts as seen from space.
Thermometer: Measures temperature.
Wind Vane: Indicates the direction wind is blowing from.
