The FAA manages several weather observation programs including

• Aviation Surface Weather Observation Network — measures weather parameters on the surface and reports conditions
• Next Generation Weather Radar — detects, processes, and distributes for display hazardous and routine weather information
• Terminal Doppler Weather Radar — provides vital information and warnings about hazardous wind shear conditions, precipitation, gust fronts, and microbursts
• Wind Shear Detection Services — provides alerts and warnings of hazardous wind shear

These weather observation programs increase the safety of the nation's airspace by detecting hazardous conditions and reducing weather-related delays and accidents.
