Abstract:
Remote sensing data from global observing satellites, combined with data from ecosystem models, offers an unprecedented opportunity for understanding and predicting the behavior of the Earth's ecosystem. This data consists of a sequence of global snapshots of the Earth, and includes various atmospheric, land and ocean variables such as sea surface temperature (SST), pressure, precipitation, vegetation index (NDVI), and Net Primary Production (NPP). Due to the large amount of data that is available, data mining techniques are needed to facilitate the automatic extraction and analysis of interesting patterns from the Earth Science data. However, mining patterns from Earth Science data is a difficult task due to the spatio-temporal nature of the data. This talk will discuss various challenges involved in analyzing the data, and present some of our work on the design of efficient algorithms for finding spatio-temporal patterns from such data and their applications in discovering interesting relationships among ecological variables from various parts of the Earth. A special focus will be on techniques for land cover change detection (and their use in assessing the impact on carbon cycle) and finding teleconnections between ocean and land variables.
