Upper Atmosphere Physics Monitoring Observation at Syowa Station

The Upper Atmosphere Physics Monitoring (UAPM) data consist of the magnetic variation data from the fluxgate magnetometer at Syowa Station, and other items at West Ongul island: CNA data from the riometer; ULF magnetic pulsation data from the induction magnetometer; and the natural electromagnetic wave emission data in the ELF/VLF band from the ELF/VLF receiver. A digital recording system for the UAPM data was installed by JARE-22 in 1981. The recording system has been changed from the initial mini-computer system to a more compact system. At present, a PC-based Linux OS system, called as ATLAS, is running. Data stored in HD are copied to MO every month. 10 and 1 second data are transferred to NIPR every 1 hour and 1 day, respectively, via Intelsat satellite network.高层大气物理监测（Upper Atmosphere Physics Monitoring, UAPM）数据集包含昭和站磁通门磁力仪（fluxgate magnetometer）采集的磁变数据，以及西翁古尔岛的其他观测项目数据：来自电离层噪声计（riometer）的CNA数据、感应磁力仪（induction magnetometer）获取的超低频（ULF）磁脉动数据，以及极低频/甚低频（ELF/VLF）接收机采集的ELF/VLF频段自然电磁波辐射数据。1981年，第22次日本南极考察队（JARE-22）搭建了该数据集的数字记录系统。该记录系统已从最初的小型计算机系统升级为更为紧凑的架构。目前，一套名为ATLAS的基于PC的Linux操作系统正在运行。存储于硬盘（HD）中的数据每月会被拷贝至磁光盘（MO）。10秒分辨率与1秒分辨率的数据分别通过Intelsat卫星网络，以每小时和每天的频次传输至日本国立极地研究所（National Institute of Polar Research, NIPR）。
