Wind Field Detection in the Stratosphere and Troposphere Using High-resolution Oxygen-corrected Laser Heterodyne Radiometer (LHR)

News

Researchers at the University of Science and Technology of China have developed a near-infrared (NIR) dual-channel oxygen-corrected laser heterodyne radiometer (LHR) to measure the vertical profile of wind fields in these regions with high accuracy.
