Abstract: A cloud radar apparatus is mounted on a portable containerized unit, a number of which may be located at various positions throughout the planet. Cloud radar data from each unit are periodically measured and stored and made available to researchers, upon request, through the Internet or other network. The system comprises two computers operating on different operating systems. A first computer uses a first operating system which allows it to readily interface with various radar equipment using an IEEE 488 interface or the like, to monitor the health of the equipment and operate the equipment. A second computer system uses a second operating system in a multi-user mode which allows it to readily access and manipulate data files and transfer data over the network. Communication between the two computers is achieved by allowing the first computer to log into the second computer as one of the multiple users. The first computer may upload data to the second computer using a FTP protocol or the like.
