all observational operations that rely on the optical properties of atmospheric constituents are only as good as the spectroscopic parameters obtained by laboratory spectroscopic studies.
所有依靠大气成分光学性质的观察操作的好坏均取决于实验室光谱研究所获得的光谱参数的好坏。
extension to visible and infrared parts of the spectrum is recommended, as well as similar studies for other species like no2 and hno3, where uncertainties on spectroscopic parameters remain a limiting factor.
建议将研究范围扩大到可见光和红外线,并对其他物质(如二氧化氮和硝酸)开展类似研究,因为这方面的光谱参数不确定性仍然是一项限制因素。
additional laboratory spectroscopic studies have now provided the basis for moving towards finalizing recommendations on the best ozone absorption cross-sections in the ultra-violet.
更多的实验室光谱研究现已为最终确定有关最佳紫外线臭氧吸收截面的建议奠定了基础。
