Abstract
AbstractA scalable datalogging system for micrometeorological, fast-response, in situ, and remote sensing applications is presented. The system is based on a standard x86 MINI-ITX computer and the open-source operating system Linux. Real-time access for debugging and remote system control is implemented via a network interface. A 160-GB, 2.5-in. hard disk drive provides extended local storage. The recorded data can alternately be stored at a remote location using the Network File System (NFS) included in Linux. Accurate time stamping of collected data points is implemented using the open-source software Network Time Protocol (NTP) and a global positioning system (GPS) receiver. The operational capability of the system is demonstrated over a period of several weeks with data from seven ultrasonic anemometer–thermometers and a barometer.
