GOES satellites are geostationary weather satellites run by NOAA.

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. The brightness temperature at the Top-Of-Atmosphere (TOA) is measured in Kelvin. These bands support the characterization of the surface, clouds, water vapor, ozone, volcanic ash, and dust based on emissive properties.

The locations of domains 1 and 2 change over time.

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、火山灰和灰尘进行描述。

域1和域2的位置随时间变化。
