Chinese-European Dragon Programme Marks Ten Years of Satellite Earth Observation Cooperation

The Poyang lake in southern China’s Jiangxi province is the largest freshwater lake in the country.

This lake is an important habitat for migrating Siberian cranes – many of which spend the winter there. The basin is also one of China’s most important rice-producing regions, although local inhabitants must contend with massive seasonal changes in water level.

In addition to seasonal changes, a team of scientists working under ESA’s Dragon programme have identified an overall decrease in water level in the lake over the last decade.

Led by Prof. Huang Shifeng from Beijing’s Institute of Water and Hydraulic Resources and Dr Hervé Yesou from SERTIT in France, the team used radar and optical imagery primarily from ESA’s Envisat satellite, supplemented with data from ESA Third Party and Chinese missions.

The Envisat mission ended in 2012, but the recently launched Sentinel-1A satellite continues the legacy by providing high-resolution radar data for inland water monitoring, among many other applications.

The scientists are using the data to improve our understanding of the lake’s water surface dynamics – information useful for flood mitigation, habitat mapping, ecological characterisation and measuring the water cycle’s impact on human health.

The project also concentrates on a unique synergistic exploitation of data from different types of space-based sensors – synthetic aperture radar, optical and altimeter – for water monitoring. As new radar data from Sentinel-1 become available, combining these new data with 20 years of measurements from previous satellite radar missions is key for mapping the long-term changes of this and other areas across the globe.

Poyang is just one of the many project areas of the collaborative Chinese-European Dragon Programme, which marks its ten-year anniversary this week.

As a joint undertaking between ESA and the National Remote Sensing Center of China (NRSCC), under the Ministry of Science and Technology (MOST) of China, the programme promotes the use of ESA, Third Party Mission and Chinese Earth observation satellite data within China for science and applications.

Over the past decade, the programme has significantly grown. The annual Dragon symposium held this week in Chengdu, China, was attended by MOST Vice Minister, Dr Cao Jianlin, and saw over 300 participants – double the number at the inaugural symposium in 2004. This programme has been recognised by both NRSCC and ESA as a model for successful scientific cooperation between Europe and China.
