Abstract:

[Objective] Natural disasters in China have shown a complex situation of multiple and frequent occurrence with global climate change. Rapid, accurate, and efficient scientific data support is an important basis for making disaster emergency response plans, reducing disaster losses, preventing secondary disasters, and helping post-disaster reconstruction. [Methods] Since the National Cryosphere Desert Data Center (NCDC ) launched the scientific data emergency service for the Nepal earthquake in 2015, nine data engineering systems, including multidisciplinary linkage emergency response, multi-source data referral and aggregation, multi-source data fusion and integration, thematic data preparation, emergency data organization, disaster evolution analysis, disaster extent assessment, secondary disaster assessment and early warning, and data sharing and pushing services, have been implemented in NCDC. [Results] A scientific data emergency response service platform has been built to quickly provide data emergency response within 24 hours after a disaster, and has now completed 16 scientific data emergency response services for earthquakes in Sunan Zhangye, Gansu Province; Mado, Menyuan, Monya and Delingha in Qinghai Province; and Markang, Luding and Lushan in Sichuan Province, Turkey, Afghanistan, Tajikistan and Datong flash floods in Qinghai Province, providing scientific data support for disaster relief, disaster investigation and assessment, and post-disaster reconstruction. [Conclusion] This work makes innovation in the application scenario of scientific data for disaster prevention and mitigation. As of March 2023, more than 189,000 persons have downloaded 2.6PB of data and formed a good effect in these applications.
