简介:Google Earth Engine(GEE)——Landsat8/modis/sentinel2 NDVI时序影像差异对比分析图表 很多时候我们只管使用数据,而不知道数据之间的差异在那里,所以我们可以选择相同的点然后加载不同的数据集,然后查看某个点的时序影像来实现影像差异对比。 Landsat 8是由美国地质调查局(USGS)运行的陆地观测卫星,于2013年发射。

The Cloud and Moisture Imagery products are all at 2km resolution. Bands 1-6 are reflective. The dimensionless "reflectance factor" quantity is normalized by the solar zenith angle. These bands support the characterization of clouds, vegetation, snow/ice, and aerosols. Bands 7-16 are emissive. ...

云层和水分图像产品的分辨率都是2公里。1-6波段是反射的。无尺寸的 "反射系数 "数量是以太阳天顶角为标准的。这些波段支持云、植被、雪/冰和气溶胶的特征。频段7-16是发射型的。大气层顶部(TOA)的亮度温度以开尔文测量。这些波段支持根据发射特性对地表、云层、水汽、臭氧、火山灰和灰尘进行定性。
Cirrus clouds are thin, transparent or semi-transparent clouds, forming at high altitudes, approximately 6-7 km above the Earth's surface. The method of identifying cirrus cloud pixels from dense cloud pixel is based on two spectral criteria: ...
These bands support the characterization of the surface, clouds, water vapor, ozone, volcanic ash, and dust based on emissive properties. README GOES卫星是由NOAA管理的地球静止气象卫星。 云层和水分图像产品的分辨率都是2公里。1-6波段是反射的。无尺寸的 "反射系数 "数量是以太阳天顶角为标准的。这些...
