Field measurement of atmospheric CO₂ column abundance based on portable laser heterodyne radiometer

Field measurement of atmospheric CO₂ column abundance based on portable laser heterodyne radiometer

This study presents a portable near-infrared laser heterodyne radiometer specifically designed for measuring the column abundance of atmospheric carbon dioxide (CO₂) in the Taiyuan area. The instrument modulates the solar radiation using a fiber optic switch and amplifies the solar radiation through...
