How do imagery satellites work?

Satellites use different kinds of sensors to collect electromagnetic radiation reflected from the Earth. Passive sensors collect radiation which the Sun emits and the Earth reflects and don’t require energy. Active sensors emit radiation themselves and analyze it after it is reflected back from the Earth.

How does a satellite image help in assessing the weather?

Satellite imagery has been an immense benefit to weather forecasters. With it they can assess aviation hazards such as low clouds monitor thunderstorms and track the evolution of dust plumes. … However barriers can prevent experimental products from reaching forecasters in the operational environment.

Why do meteorologists use satellites?

These geostationary satellites are principally used to provide images of the Earth which when looped together allow meteorologists and the public to see the growth and movement of clouds and storms in the atmosphere. This information is especially critical for short-term forecasting or nowcasting of severe weather.
