106 Surface Observation Fundamentals Practice Exam

A METAR report is a standardized format used for providing essential weather information at airports and aerodromes. It includes a variety of specific data points that are crucial for pilots and meteorologists to understand current weather conditions for safe flight operations.

The correct answer includes temperature, dew point, wind direction and speed, visibility, weather phenomena, and altimeter setting, all of which are integral components of a METAR report. Let's break down these elements:

- **Temperature**: Indicates the current air temperature, which is critical for assessing weather conditions and helps in flight planning.

- **Dew Point**: This measurement provides insight into humidity and the likelihood of clouds and precipitation forming, which are vital for understanding weather patterns.

- **Wind Direction and Speed**: Wind data is crucial for takeoff and landing procedures. It informs pilots about potential crosswinds or tailwinds.

- **Visibility**: This measure is crucial for safe air navigation, as it affects pilots’ ability to see the runway and other aircraft.

- **Weather Phenomena**: Information about significant weather events, such as rain, snow, fog, or thunderstorms, is included to warn pilots of adverse conditions.

- **Altimeter Setting**: This value is essential for ensuring that pilots can
