METEOROLOGY – CLOUD & VIIBILITY CALCULATOR
Met Visibility Extinction
A precise tool.
What is the Met Visibility Extinction & How does it work?
Visibility in meteorology is a measure of the maximum distance at which an object can be clearly distinguished from its background under specific atmospheric conditions.
The extinction coefficient ((k_e)) represents the rate at which light intensity decreases as it travels through a medium, such as air containing particles. It is crucial in determining visibility.
Visibility (V) = frac{L}{k_e}
V = Visibility, L = Path length of light, k_e = Extinction coefficient

Frequently Asked Questions
What is the formula for calculating visibility?
Visibility (V) = Path length of light (L) / Extinction coefficient (k_e).
How does the extinction coefficient affect visibility?
A higher extinction coefficient means more light is absorbed or scattered, reducing visibility.
What factors can increase the extinction coefficient in the atmosphere?
Factors like pollution, dust, fog, and smoke particles can increase the extinction coefficient.
How does path length of light affect visibility?
A longer path length means more interaction with atmospheric particles, potentially reducing visibility.
Can you explain what visibility means in meteorology?
Visibility in meteorology is the maximum distance at which an object can be clearly distinguished from its background under specific atmospheric conditions.
Why is it important to measure visibility?
Measuring visibility helps in understanding air quality, planning travel routes, and assessing weather conditions.
How does temperature affect visibility?
Temperature can influence the amount of moisture in the air, which in turn affects visibility. Lower temperatures often lead to clearer air.
