从光波的衰减测量决定大气气溶胶的谱分布

本文对从光波的衰减测量决定大气气溶胶谱分布进行理论研究。应用泛函理论,证明了在消光截面取Van de Hulst近似公式时,第一类Fredholm积分方程有唯一解。从而确证频谱法探测大气气溶胶是可能的。同时还研究了这种探测的反演计算、误差分析、有效信息量和如何选择最优波段等问题。 关键词：

DETERMINATION OF THE SIZE DISTRIBUTION OF ATMOSPHERIC AEROSOLS BY MEANS OF MEASUREMENT OF OPTICAL ATTENUATION

In this article we made a theoretical investigation on determination of size distribution of atmospheric aerosoils by means of measurement of optical attenuation. We showed that the Predholm integral equation of the first kind has only one solution when attenuation cross-section is given by Van de Hulst approximate equation. We thus proved that remote sensing of atmospheric aerosoils by variation of optical wave lengths is possible. We also studied the problems of inversion computation, analyses of errors, effective information and selection of the optimal optical wave lengths associated with this remote sensing process.
