Differential Absorption Lidar (DIAL) is an advanced remote sensing technology used to measure atmospheric gases, particularly greenhouse gases like carbon dioxide (CO2) and methane (CH4).
THE absorption of the hydrogen resonance line at 1215·7 A. has been investigated to obtain more exact information bearing on the theory of the production of short-wave radio fadeouts by solar ...
