摘要

在氧a波段内以20 cm/sup -1/光谱分辨率(使用了LOWTRAN大气数据库)计算了(通过Fredholm积分方程)卫星测量的辐射变化与气溶胶消光剖面变化之间的气溶胶核函数。内核最初是在吸收带外的近红外区域的波长上进行评估的。尽管应该采用更高的光谱分辨率来充分利用氧波段的可能性，但即使是20厘米/sup -1/分辨率也可以提供更好的信息内容，并且相对于先前研究的波长有更高的精度:实际上，检索的相对误差大约减少了一半。

Aerosol profile variations retrieval through Kernel functions in the oxygen absorption band at 762 nm

The aerosol kernel functions, relating (through a Fredholm integral equation) the variations in radiance measured by satellites to the variations of aerosol extinction profile, have been computed with a 20 cm/sup -1/ spectral resolution within the Oxygen A-band (LOWTRAN atmospheric database has been used). The kernel was originally evaluated at wavelengths in the near infrared region outside absorption bands. Notwithstanding the fact that a higher spectral resolution should be adopted to fully take advantage of the Oxygen band possibilities, even the 20 cm/sup -1/ resolution permits a better information content and an improved accuracy with respect to the wavelengths previously investigated: indeed the retrieval relative error is approximately reduced by a half.

期刊介绍： Remote Sensing Information is a bimonthly academic journal supervised by the Ministry of Natural Resources of the People's Republic of China and sponsored by China Academy of Surveying and Mapping Science. Since its inception in 1986, it has been one of the authoritative journals in the field of remote sensing in China.In 2014, it was recognised as one of the first batch of national academic journals, and was awarded the honours of Core Journals of China Science Citation Database, Chinese Core Journals, and Core Journals of Science and Technology of China. The journal won the Excellence Award (First Prize) of the National Excellent Surveying, Mapping and Geographic Information Journal Award in 2011 and 2017 respectively. Remote Sensing Information is dedicated to reporting the cutting-edge theoretical and applied results of remote sensing science and technology, promoting academic exchanges at home and abroad, and promoting the application of remote sensing science and technology and industrial development. The journal adheres to the principles of openness, fairness and professionalism, abides by the anonymous review system of peer experts, and has good social credibility. The main columns include Review, Theoretical Research, Innovative Applications, Special Reports, International News, Famous Experts' Forum, Geographic National Condition Monitoring, etc., covering various fields such as surveying and mapping, forestry, agriculture, geology, meteorology, ocean, environment, national defence and so on. Remote Sensing Information aims to provide a high-level academic exchange platform for experts and scholars in the field of remote sensing at home and abroad, to enhance academic influence, and to play a role in promoting and supporting the protection of natural resources, green technology innovation, and the construction of ecological civilisation.
