Abstract
We devised a low-cost continuous digital recording system, which consists of a personal computer as CPU, 2 sets of A/D converter and buffer memory, DAT (Digital Audio Tape) data storage system, clock and UPS (Unbroken Power Supply). This system, having 1000-megabyte recording capacity, can make continuous data acquisition for about 70 days in case of 4-channel input and 20 Hz sampling. Also, portability of this system enables us to start field observation quickly. The acquired data are edited for every 10 minutes and stored on the DAT data storage system in binary format. We made test observation at Ajiro Weather Station (which belongs to JMA) and have confirmed the reliability of this system.
