 Remote sensing atmospheric boundary layer

Remote sensing of the atmospheric boundary layer (ABL) refers to the techniques and technologies used to observe, measure, and analyze the lower part of the atmosphere, typically extending from the Earth's surface up to about 1-2 kilometers (or up to several kilometers in specific contexts) in altitude. The ABL is a crucial component of the Earth's atmosphere, where many weather phenomena occur, and it plays a key role in the exchange of energy, moisture, and pollutants between the surface and the atmosphere.
