Satellite observations

Definition

Satellite observations refer to the use of satellites equipped with remote sensing technology to collect data about the Earth's atmosphere, surface, and weather systems from space. This powerful tool allows for continuous monitoring and analysis of various atmospheric phenomena, making it essential for understanding the vertical structure of the atmosphere, severe weather events, forecasting, and improving numerical weather prediction models.
