Satellite observation

Definition

Satellite observation refers to the use of satellites equipped with remote sensing technology to collect data about the Earth's atmosphere, land, and oceans from space. This technique provides critical information for monitoring weather patterns, climate change, and natural disasters, allowing scientists to analyze the interactions between different components of Earth's atmospheric system.
