非局域热力学平衡大气的红外辐射传输研究

The excitation and de-excitation of emission, collision and photochemistry for non-local thermodynamic equilibrium atmospheric molecules were studied. The models of the populations of molecular vibrational levels, and an accurate and fast line-by-line algorithm of solving the joint and nonlinear of the equations of radiative transfer and the equations of statistical equilibrium were developed to evaluate the populations and vibrational temperature profiles of the infrared-active molecular vibrational levels. Effects of infrared radiation on the limb and vertical scanning instruments, and atmospheric remote sensing were studied. This project can be directly applied to atmospheric remote sensing and space defense.
