基金Funding for GPS telemetry was provided by the International Crane Foundation, U.S. Forest Service, and the Paulson Institute. The animal capturing and marking permits were granted by the Ministry of Environment, Green Development, and Tourism of Mongolia to the Mongolian Wildlife Science and the Conservation Center. We thank Peter Mann for providing useful comments. We feel grateful to the European Space Agency (ESA) for providing the Sentinel-1 data. We finally thank the Sino-European joint research DRAGON 4 cooperation (ID. 32442. New Earth Observation Tools for Water Resource and Quality Monitoring in Yangtze Wetlands and Lakes) initiated within the ESA, MOST & NRSCC cooperation for initiating the collaboration.
