Atmospheric profiling

Definition

Atmospheric profiling is the process of measuring and analyzing the vertical structure of the atmosphere, which includes temperature, humidity, pressure, and wind speed at various altitudes. This information is essential for understanding weather patterns, forecasting, and climate studies. Atmospheric profiling utilizes different remote sensing technologies to gather data from the surface up through the troposphere and beyond, offering insights into atmospheric conditions that are not easily accessible through traditional ground-based observations.
