China plans to put four more Fengyun-3 meteorological satellites into orbit between 2018 and 2021, China Aerospace1 Science and Technology Corporation (CASTC) announced Wednesday.

中国航天科技集团公司周三宣布，中国计划在2018年至2021年间再发射四颗风云3号气象卫星。

The Fengyun-3, including a morning orbit satellite, an afternoon orbit satellite and a precipitation measuring satellite, will form a network of low-orbit meteorological satellites to enhance the monitoring of atmospheric2 humidity and temperature, greenhouse gases, wind fields and precipitation, said Zhou Xubin with the CASTC.

The launch of the Fengyun-3 satellites will help shorten the interval3 between world weather forecast updates from the current six hours to four hours, and increase the timeliness of weather disaster monitoring and forecast accuracy, said Zhou.

China launched the Fengyun-3D at 2:35 a.m. Beijing Time Wednesday from the Taiyuan Satellite Launch Center in northern China’s Shanxi Province.

Fengyun satellites are a series of remote-sensing meteorological satellites developed by China. Fengyun-1 and Fengyun-3 are polar orbiting weather satellites, while Fengyun-2 and Fengyun-4 operate in geostationary orbit.
