To improve the spatial resolution of the global aerosol optical depth (AOD) distribution, a new method for AOD retrieval is proposed over land in this paper. A monthly Global Land Surface Reflectance Database (GLSRD) was constructed using the long time serious of MODIS surface reflectance product (MOD09A1) and used for the surface reflectance estimation over land for AOD retrieval. A seasonal Global...
This paper presents an improved method of selective ensemble to filter the spam messages. The design adopts clustering based on the diversity between sub-classifiers to solve the problem of selection. To improve accuracy and stability, a conception of confidence weight is proposed to evaluate the reliability of selected sub-classifiers. The training model is created with small datasets as in the real...
The resolution of current MODIS aerosol optical thickness (AOT) product is 10 km. This product is suitable for global research, but it faces difficulty in local area research, especially in a city. In order to get detail aerosol distribution in local area or a city, this article mainly discussed how to retrieve 1 km resolution AOT and how to estimate surface reflectance in the visible from archived...
This paper introduces the development of a web-based decision support system, to facilitate human factor studies regarding the use of changeable message signs (CMS). A microscopic traffic simulator VISSIM was used to generate realistic simulation scenarios with various CMS alternatives implemented. A case study for truck mounted changeable message sign on an urban multilane highway for ldquoright...
