Satellite to give early warning of disasters
Print Edition
CHINA has plans to launch a satellite around 2020 that will help forecast disasters such as floods and drought.
The Water Cycle Observation Mission satellite, which will provide integrated observation of key elements of the global water cycle, was announced at the International Geoscience and Remote Sensing Symposium 2016 in Beijing.
The WCOM project is a joint initiative of the Institute of Remote Sensing and Digital Earth and the National Space Science Center with the Chinese Academy of Sciences.
The CAS has completed key research and tests of the satellite’s payload in anticipation of further development.
“This year’s floods in southern China are an example of how changes in water cycle have a direct impact on our lives,” said Shi Jiancheng, chief WCOM scientist.
“Understanding the distribution characteristics and changing patterns of the water cycle and forecasting them are frontier scientific issues for us,” Shi added.
The satellite will provide accurate observations through simultaneous monitoring of key water cycle elements, such as soil humidity, snow/water equivalents, surface ice and sea water salinity, Shi said.
It will play an important role in flood prevention, drought relief, agriculture, water resource management as well as food and environmental security, he said.
The CAS will cooperate with US and European research teams to initiate a satellite constellation based on the WCOM, aiming to form a worldwide water cycle observation network.
Also at the Beijing symposium, progress was made in major collaborative research projects, including the China-France Oceanography Satellite and the Dragon Program.
The first joint satellite development between China and France, scheduled for launch in 2018, is dedicated to ocean wind and wave observation. A prototype model is complete and the actual prototype is being developed.
It will carry two payloads — a wave spectrometer from France and a wind scatterometer from China. It will be the first time for both devices to be used for remote-sensing purposes by a satellite.
China is responsible for the satellite design, manufacture and launch.
The Dragon Program is a cooperation between the Ministry of Science and Technology and the European Space Agency which began in 2004.
Scheduled to be completed in 2020, the fourth phase of the program consists of 27 projects covering fields including agriculture, carbon dioxide monitoring and disaster mitigation.
