报告人简介：

Professor Nicolaas Sneeuw is a globally distinguished scholar in the fields of geodesy and its hydrological applications. He is the Head of Institute of Geodesy and serves as the Vice Dean of the Faculty of Aerospace Engineering and Geodesy at the University of Stuttgart. Over the years, Professor Sneeuw has made significant contributions to the international geodetic community, including his long-standing role as Chair of the Joint Commission of the International Association of Geodesy (IAG) and as Chair of Working Group 7 (DVW, AK7) of the German Association of Surveying. In addition, he chairs the China Committee at the University of Stuttgart and acts as the foreign director of the International Cooperation Joint Laboratory for Modern Geodesy and Geodynamics at Wuhan University. Professor Sneeuw has pioneered groundbreaking research in a wide range of areas, including satellite gravity missions, hydro-geodesy, and satellite geodesy theory, making profound and far-reaching contributions to the advancement of these disciplines. Notably, he is among the first international scholars to employ geodetic space observation techniques for monitoring hydrological mass changes, establishing a foundation for innovative exploration in this field.

报告摘要：

Hydrogeodesy deals with the quantification of processes in the hydrological cycle using multi-technique remote sensing. In this lecture I will identify which storages and fluxes within the global water cycle can be observed through geodetic means. Two concrete examples serve as illustration. In the first example we characterize the runoff-storage relation for large catchments. Together with satellite gravimetry we then predict runoff from the partially unobserved boreal catchments into the Arctic Ocean. In the second example we counteract the decline of the global discharge database within the Global Runoff Data Center (GRDC) using both satellite altimetry and optical remote sensing.
