Earth observations, model simulations, and climate reanalysis produce vast amounts of climate data. The unprecedented data volume and intrinsic complexity of geospatial statistics and analysis requires efficient analysis to investigate global problems such as climate change, natural disasters, diseases, and other environmental issues. However, this requirement poses grand challenges due to the unprecedented data volume and intrinsic complexity of geospatial statistics and analysis. Addressing these challenges requires efficient data management strategies, complex parallel algorithms and scalable computing systems.
This project aims to address these challenges by developing an efficient spatiotemporal indexing approach (Li et al., 2016), an innovative query analytical framework (Li et al., 2017), and a scalable online visual analytical system called SOVAS for interactive big climate data analysis (Li et al., 2019).
