POES Space Environment Monitor|卫星监测数据集|空间环境数据集

The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. The Earth's rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of weather around the world each day. NOAA partners with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to constantly operate two polar-orbiting satellites – one POES and one European polar-orbiting satellite called Metop. NOAA's Polar Orbiting Environmental Satellites (POES) carry a suite of instruments that measure the flux of energetic ions and electrons at the altitude of the satellite. This environment varies as a result of solar and geomagnetic activity. Beginning with the NOAA-15 satellite, an upgraded version of the Space Environment Monitor (SEM-2) has been flown.

极地轨道环境卫星系统（POES）凭借其每日全球覆盖的优势，通过每日绕地球近极地轨道14圈，大约在地球表面上方520英里处运行。地球的自转使得卫星在每个轨道上都能观察到不同的视角，而每颗卫星每天都能提供全球天气的两次完整视图。美国国家海洋和大气管理局（NOAA）与欧洲气象卫星应用组织（EUMETSAT）合作，持续运行两颗极地轨道卫星——一颗为POES，另一颗为名为Metop的欧洲极地轨道卫星。NOAA的极地轨道环境卫星（POES）携带有套测量卫星高度处能量离子和电子通量的仪器。由于太阳活动和地磁活动的影响，这一环境不断变化。从NOAA-15卫星开始，一种升级版的太空环境监测器（SEM-2）被部署使用。
