Korea Meteorological Administration (KMA) GK-2A Satellite Data

The Geo-KOMPSAT-2A (GK2A) is the new generation geostationary meteorological satellite (located in 128.2°E) of the Korea Meteorological Administration (KMA). The main mission of the GK2A is to observe the atmospheric phenomena over the Asia-Pacific region. The Advance Meteorological Imager (AMI) on GK2A scan the Earth full disk every 10 minutes and the Korean Peninsula area every 2 minutes with a high spatial resolution of 4 visible channels and 12 infrared channels. In addition, the AMI has an ability of flexible target area scanning useful for monitoring severe weather events such as typhoon and volcanic eruption and so on. And for space weather mission, the Korea Space wEather Monitor (KSEM) on the GK2A observes the space environment with the particle detector, magnetometer and charging monitor.

Geo-KOMPSAT-2A（GK2A）系韩国气象厅（KMA）新一代地球同步气象卫星（位于东经128.2°），其主要任务是对亚太地区的大气现象进行观测。搭载的先进气象成像仪（AMI）能够以每10分钟扫描一次地球全盘、每2分钟扫描一次朝鲜半岛区域的频率，以高空间分辨率（4个可见光通道和12个红外通道）对地球进行成像。此外，AMI具备灵活的目标区域扫描能力，有助于监测如台风和火山爆发等极端天气事件。对于太空天气预报任务，GK2A上的韩国空间天气预报监测器（KSEM）通过粒子探测器、磁力计和电荷监测器对空间环境进行观测。有关GK2A成像规格的疑问，请访问GK2A网站<a href="https://nmsc.kma.go.kr/enhome/html/base/cmm/selectPage.do?page=satellite.gk2a.intro">https://nmsc.kma.go.kr/enhome/html/base/cmm/selectPage.do?page=satellite.gk2a.intro</a>。欲查阅GK2A事实说明书，请访问<a href="https://nmsc.kma.go.kr/enhome/html/base/cmm/selectPage.do?page=satellite.gk2a.fact">https://nmsc.kma.go.kr/enhome/html/base/cmm/selectPage.do?page=satellite.gk2a.fact</a>。美国国家海洋和大气管理局（NOAA）与韩国气象厅协调，在亚马逊网络服务（AWS）上提供GK2A数据访问。
