Spherical Elementary Current Systems Instrument

The Spherical Elementary Current Systems instrument is a virtual instrument representing the collection of ground magnetometer arrays used to derive spherical elementary currents over North America and Greenland at 10 s resolution. The SECS observatory consists of ground magnetometers from the CANMOS, CARISMA, DMI (in Greenland), GIMA, MACCS, THEMIS, STEP ground magnetometer arrays. Ground magnetometers contributing to each SECS data file may vary from day to day depending upon data availability. As result, the SECS instrument is used as a proxy for the set of possible contributing ground magnetometers. Complete details on the magnetometer arrays at the Information URLs listed below.

球面基本电流系统仪器是一种虚拟仪器，代表着用于从北美和格陵兰岛推导出10秒分辨率的球面基本电流的地面磁力仪阵列集合。SECS观测站由CANMOS、CARISMA、DMI（位于格陵兰岛）、GIMA、MACCS、THEMIS、STEP地面磁力仪阵列的磁力仪组成。贡献于每个SECS数据文件的地面磁力仪可能因数据可用性而每日有所不同。因此，SECS仪器被用作可能贡献地面磁力仪集合的代理。关于以下信息URL中列出的磁力仪阵列的详细信息，请查阅完整说明。
