Abstract

The latest generation of geostationary satellites carry sensors such as the Advanced Baseline Imager (GOES-16/17) and the Advanced Himawari Imager (Himawari-8/9) that closely mimic the spatial and spectral characteristics of widely used polar orbiting sensors such as EOS/MODIS. More importantly, they provide observations at 1-5-15 minute intervals, instead of twice a day from MODIS, offering unprecedented opportunities for monitoring large parts of the Earth. In addition to serving the needs of weather forecasting, these observations offer new and exciting opportunities in managing solar power, fighting wildfires, and tracking air pollution. Creation of actionable information in near realtime from these data streams is a challenge that is best addressed through collaborative efforts among the industry, academia and government agencies.
新一代地球同步卫星的地球观测
最新一代地球静止卫星携带传感器,如先进基线成像仪(GOES-16/17)和先进Himawari成像仪(Himawari-8/9),这些传感器密切模仿广泛使用的极轨传感器(如EOS/MODIS)的空间和光谱特征。更重要的是,它们每隔1-5-15分钟提供一次观测,而不是MODIS每天两次,为监测地球的大部分地区提供了前所未有的机会。除了满足天气预报的需要外,这些观测还为管理太阳能、扑灭野火和跟踪空气污染提供了令人兴奋的新机会。从这些数据流中创建近乎实时的可操作信息是一项挑战,最好通过行业、学术界和政府机构之间的合作努力来解决。
