A new approach of generating atmospheric path radiation images based on atmospheric radiation transmittance theory

摘要

Atmospheric path radiation is an important source to monitor atmospheric pollution and quality effectively due to its feature depending on the status of atmosphere only but not involving ground information. Based on atmospheric radiation transmittance theory, a new approach of generating atmospheric path radiation images for inhomogenous atmosphere over land on MODIS remote sensing images is proposed through quantitative analysis of Rayleigh scattering and Lorenz-Mie scattering in the paper. The experimental result shows that this approach is able to generate atmospheric path radiation images under inhomogenous atmosphere over land effectively. Meanwhile, comparing with 6S proves its worth and validity obviously. Overall, this approach provides another innovative way to study on atmospheric environment field in the future.
