气象卫星已成为天气和陆地观测不可替代的工具。传统上，地球静止卫星由于其时间分辨率高的特性，通常用于业务气象服务。而极轨卫星由于其高空间分辨率的特性，更多地用于监测环境变化和自然灾害。中国下一代地球静止气象卫星（风云四号系列）的发展标志着中国非气象遥感能力的令人兴奋的发展。风云四号系列的第一颗卫星（风云四号A）于2016年12月11日发射。FY-4A上的高级地球同步辐射成像仪（AGRI）有14个光谱波段（从FY-2的五个波段增加），每像素12位量化（从FY-2的10位增加），并在可见光（维斯）、近红外（NIR）和其余红外光谱带的最低点1公里处采样（相比之下，FY-2的维斯为1.25公里，无近红外，红外为5公里）。对于FY-4A后续系列，AGRI通道数将从14个逐渐增加到18个，红外空间分辨率为2 km，全盘时间分辨率将从15分钟提高到5分钟。随着光谱、空间和时间分辨率的提高，FY-4系列将在空间和光谱分辨率上逐渐接近LEO传感器，这将为观测陆地、海洋和大气的细微物体和快速变化提供更大的机会和能力。本文介绍了中国风云四号气象卫星的观测能力、与其他新一代静止轨道气象卫星的比较以及相关的非气象应用。展示和讨论了一系列典型实例，这些实例基于国家海洋管理中心/中国气象局最近和正在进行的业务工作，正在将FY-4A数据用于非气象应用，包括：（一）气溶胶监测;（二）沙尘暴监测;（三）火山灰探测和航空应用;（四）火灾探测和动力学评价;（五）水体探测;（六）蓝藻水华监测。本文最后综合了这些应用领域和挑战，我们必须解决未来的研究，技术创新和深入的应用。
Meteorological satellites have become an irreplaceable tool for weather and land observation. Traditionally, geo-stationary satellites are commonly used in operational meteorological services due to their high temporal resolution properties. While polar-orbiting satellites, with their high spatial resolution properties, are more applied to monitor environmental change and natural disasters. The development of China’s next-generation geostationary meteorological satellites (FY-4 series) represents an exciting expansion in Chinese Non-meteorological remote sensing capabilities. The first satellite (FengYun-4A) of the FY-4 series was launched on 11 December 2016. The Advanced Geosynchronous Radiation Imager (AGRI) on board FY-4A has 14 spectral bands (increased from the five bands of FY-2) that are quantized with 12 bits per pixel (up from 10 bits for FY-2) and sampled at 1 km at nadir in the visible (VIS), 2 km in the near-infrared (NIR), and 4 km in the remaining IR spectral bands (compared with 1.25 km for VIS, no NIR, and 5 km for IR of FY-2). For the following series of FY-4A, the AGRI channel number will be gradually increased from 14 to 18 with IR spatial resolution of 2 km, and the full-disc temporal resolution will be enhanced from 15 to 5 min. With their improved spectral, spatial and temporal resolution properties, the FY-4 series will gradually approach the LEO sensors in spatial and spectral resolutions, which will offer greater opportunities and capacities for observing fine objects and rapid change of land, ocean and atmosphere. This review paper provides an introduction to the Chinese FY-4 observation capabilities, comparison of FY-4 with other new generation geo-stationary weather satellites, and associated non-meteorological applications. A series of typical examples based on recent and on-going operational work in NSMC/CMA that are using FY-4A data for non-meteorological applications were demonstrated and discussed, including (i) Aerosol monitoring; (ii) Sand storm monitoring; (iii)Volcanic ash detection and aviation applications ; (iv) Fire detection and dynamical evaluation; (v) Water body detection and (vi) Cyanobacterial Blooms monitoring. The paper concludes with a synthesis of these application areas and challenges we have to address for future research, technological innovation and in-depth applications.
