Sentinel-2A卫星(又叫哨兵卫星2号)是欧洲航天局的多光谱卫星，2015年成功发射，哨兵卫星上的多光谱仪器每10天就可以提供全球(从北纬83度到南纬56度)覆盖的10米分辨率的多光谱图像。\n哨兵2号卫星由两颗卫星组成，用于支持植被、土地覆盖和环境监测。Sentinel-2多光谱仪器沿290公里的轨道带采集了从可见光和近红外到短波红外(SWIR)等13个光谱带。10米分辨率有4个波段蓝色(490纳米)、绿色(560纳米)、红色(665纳米)和近红外(842纳米)。20米分辨率有6个波段4个窄波段用于植被表征(705纳米、740纳米、783纳米和865纳米)，2个较大的SWIR波段(1，610纳米和2，190纳米)用于雪/冰/云探测或植被湿度应力评估等应用。60米分辨率有3个波段主要用于云层屏蔽和大气校正(气溶胶为443纳米，水蒸气为945纳米，卷云探测为1375纳米)。

The Sentinel-2A satellite (also known as Sentinel-2) is a multispectral satellite of the European Space Agency, successfully launched in 2015. The multispectral instrument on the Sentinel-2A satellite can provide 10 meter resolution multispectral images covering the globe (from 83 degrees north latitude to 56 degrees south latitude) every 10 days.\nSentinel-2 satellite consists of two satellites, used to support vegetation, land cover, and environmental monitoring. The Sentinel-2 multispectral instrument collected 13 spectral bands along a 290 kilometer orbit, ranging from visible and near-infrared to short wave infrared (SWIR). The 10 meter resolution has four bands: blue (490 nanometers), green (560 nanometers), red (665 nanometers), and near-infrared (842 nanometers). There are 6 bands and 4 narrow bands with a resolution of 20 meters for vegetation characterization (705 nanometers, 740 nanometers, 783 nanometers, and 865 nanometers), and 2 larger SWIR bands (1610 nanometers and 2190 nanometers) for applications such as snow/ice/cloud detection or vegetation humidity stress assessment. The 60 meter resolution has three bands mainly used for cloud shielding and atmospheric correction (443 nanometers for aerosols, 945 nanometers for water vapor, and 1375 nanometers for cirrus detection)
