What are the characteristics of Fengyun III?

The main tasks of satellites are: to provide global meteorological parameters such as temperature, humidity and cloud radiation for weather forecast, especially for medium-range numerical weather forecast; Monitoring large-scale natural disasters and ecological environment; Study the global environmental change, explore the laws of global climate change, and provide geophysical parameters for climate diagnosis and prediction; Provide global and regional meteorological information for professional meteorological services such as military meteorology, aviation and navigation.

Fengyun-3 is a new generation of polar-orbiting satellite, and its main features should be described from three aspects.

First, three-dimensional detection of the atmosphere will be realized. Because the satellite carries advanced microwave detectors and infrared vertical detectors, we can not only understand the surface characteristics of clouds and atmosphere, but also understand the vertical structure distribution of atmospheric temperature and humidity, which is very important for weather forecast, especially numerical forecast.

Second, realize global high-resolution observation. This is of great value to global climate and natural disaster monitoring. Fengyun-3 satellite has a strong on-board storage capacity, which can store data observed all over the world. At the same time, the China Meteorological Bureau cooperated with Sweden to establish a data receiving service in the Arctic, which can obtain global observation data and transmit them to Beijing.

The third is to achieve all-weather and full-time work. Fengyun-3 satellite is not restricted by day and night, nor is it affected by various weather conditions. It can work under various conditions and provide 24-hour observation service. This is a boon for remote sensing technology.

A new generation of polar-orbiting meteorological satellite Fengyun-3 was successfully launched from cz-4 on May 27th, 2008 1 1: 02: 29, marking a new historical stage in the development of meteorological satellites and satellite meteorology in China.
