Validation of Aerosol Optical Depth Retrieved from SPOT Satellite Images
نویسنده
چکیده
In this paper, the image-based retrieval algorithm of aerosol characteristics and surface reflectance is used to retrieve the AOD from SPOT images. The validation of retrieved AOD is made possible by using the AERONET data. Five SPOT satellite images are used to testify the algorithm. The results show that the RMSE of the retrieved AOD are 0.12 and 0.08 in XS1 and XS2 bands, although the largest error is 0.14 and some retrieved Junge ? parameter is abnormally larger than 4. Of course, more studies should be conducted to conclude the algorithm.,

Due to the effect of aerosols present in the atmosphere on the satellite images, the study of the effect of local aerosols distribution on the satellite images is important. On the other hand, the study shows that the effect of aerosols on the greenhouse gases and consequently on climate is also undeniable and as a result, this puts more emphasize on the necessity of this study. Lack of informa...
