高分六号卫星加拿大山火影像
封面图片为高分六号卫星于 2023 年 6 月 29 日拍摄的假彩色影像，展示了加拿大魁北克持续蔓延的山火（中国科学院空天信息创新研究院陈甫供图）。 图中红绿颜色为两个新增的红边波段（波段 6、5，波长 750 nm、710 nm），集中体现了叶绿素成分，而蓝色波段是新增的海水蓝波段（波段 7，波长 425 nm），对燃烧产生的烟雾反应灵敏。高分六号的宽幅传感器 (GF-6WFV) 具有“800 km 的单一镜头、单一传感器，波段数目从传统的 4 个增加到 8 个”的特点，是中国对外数据共享的一个核心数据源。它经常拍摄中国以外的区域，对于全球环境变化监测具有重要意义。该数据可从中国资

Image of wildfires in Canada by GF-6 satellite
The cover image is a false-color image taken by GF-6 satellite on June 29, 2023, showing the continuous spread of wildfires in Quebec, Canada (photo courtesy of Fu Chen, Aerospace Information Research Institute, Chinese Academy of Sciences). The red and green colors in the image are two newly added red edge bands (bands 6 and 5, wavelengths 750 nm and 710 nm), which embodies the chlorophyll component, while the blue band is the newly added seawater blue (band 7, wavelength 425 nm), sensitive to smoke generated by combustion. The wide-format sensor (GF-6WFV) of GF-6 has the characteristics of "a single lens and a single sensor of 800 km, and the number of bands has increased from the traditional 4 to 8". It is a core data source for China's data sharing. It often photographs areas outside of China and is of great significance for global environmental change monitoring. The data can be obtained free of charge from the website of CRESDA: https://www.cresda.com/zgzywxyyzx/index.html.
