The paper discussed a method which automatically detect cloud in polar orbit meteorological satellite images by using visual band reflectance and thermal infrared bright temperature.

The development of polar orbit meteorological satellite in China has experienced the processes from experiment to application.

The AVHRR data collected between 2003 and 2005 are analysized by means of the RS receiving and processing system attached to the polar orbit meteorological satellite for a better understanding of and precautions against the forest fire in the neighboring area of Harbin.

Using the visible channel (0 58-0 68 μm ), near infrared channel (1 58-1 64 μm) and infrared channel (10 3-11 3 μm) high-resolution data of polar-orbiting meteorological satellite NOAA and FY-1C and considering the cloud thickness, the particle sizes and brightness temperature of cloud top, the satellite criterions for aircraft cloud-seeding operation were given.

Fengyun 3 series are the second generation polar-orbiting meteorological satellites of China,which is expected to perform global,3-dimensional,quantitative and multi-spectral observations under all weather conditions(i.
