Understanding METAR Reports: A Guide to Airport Weather Tracking

Monitoring weather conditions at airports is crucial for pilots, air traffic controllers, and aviation enthusiasts. One of the primary tools for this purpose is the METAR report, a standardized format for weather observations.

What Is a METAR Report?

A METAR (Meteorological Aerodrome Report) is an aviation routine weather observation issued at regular intervals, typically every hour. These reports provide essential information about current weather conditions at airports, including:

• Wind: Direction and speed.
• Visibility: Distance at which objects can be clearly seen.
• Present Weather: Conditions like rain, snow, or fog.
• Sky Conditions: Cloud cover and ceiling.
• Temperature and Dew Point: Air and dew point temperatures.
• Altimeter Setting: Pressure adjusted to sea level.

Each METAR report begins with the station identifier, followed by the date and time of observation in UTC (Coordinated Universal Time). For example, a report starting with "KLIT 200953Z" indicates Little Rock National Airport (KLIT) with an observation at 09:53 UTC on the 20th of the month. (weather.gov)

Decoding a Sample METAR Report

Consider the following METAR report:

KLIT 200953Z 00000KT 4SM -RA BR OVC030 07/05 A3013 RMK AO2 SLP205

Breaking it down:

• KLIT: Station identifier (Little Rock National Airport).
• 200953Z: Date and time of observation (20th day at 09:53 UTC).
• 00000KT: Wind calm (0 knots).
• 4SM: Visibility 4 statute miles.
• -RA: Light rain.
• BR: Mist.
• OVC030: Overcast sky at 3,000 feet above ground level.
• 07/05: Temperature 7°C, dew point 5°C.
• A3013: Altimeter setting 30.13 inches of mercury.

For a comprehensive guide on decoding METAR reports, refer to the National Weather Service's training materials. (weather.gov)

How to Access METAR Reports

METAR reports are publicly available and can be accessed through various platforms:

• National Weather Service (NWS): The NWS provides METAR reports for airports across the United States. (weather.gov)
• Aviation Weather Center (AWC): The AWC offers METARs and other aviation-related weather information. (weather.gov)
