Which standard addresses siting meteorological sensors at airports?

• A. Federal Aviation Administration Handbook
• B. National Weather Service Policy
• C. International Meteorological Standard
• D. Federal Standard for Siting Meteorological Sensors at Airports

Answer: (D)

Accurate weather observations at airports depend on sensor placements that minimize local influences. The federal standard that governs this is the one dedicated to siting meteorological sensors at airports, outlining where sensors should be located, how they should be exposed, how high they should be above ground, and how they should be accessed for maintenance. This guidance ensures readings aren’t biased by nearby heat sources, pavement, structures, or equipment, so wind, temperature, pressure, and other measurements truly represent the ambient conditions around the airport. Other options point to organizations or broad international ideas, but they don’t provide the specific airport siting rules required for consistent, aviation-relevant observations.
