This paper describes a tool for providing transparent access to online meteorological databases by way of local file system. It is realized by FUSE, an implementation of usermode filesystem on Linux. A user is allowed to deal with online meteorological data as if they were stored in his/her local file systems. The main target of this tool is scientists in meteorology those who are not familiar with computers and related technologies. For this reason, we attempt to provide easy ways for configuring, maintaining, and using the system. To improve system performance, we integrate a caching mechanism for decreasing the number of HTTP requests. Key words e-Science, Infomation Integration, Meteorology
