Resolving biogeochemical processes in lakes using remote sensing

Alfred Johny Wüest, Damien Bouffard, Theo Baracchini, Vincent Maurice Nouchi

Remote sensing helps foster our understanding of inland water processes allowing a synoptic view of water quality parameters. In the context of global monitoring of inland waters, we demonstrate the benefit of combining in-situ water analysis, hydrodynamic ...

Effects of non-uniform vertical constituent profiles on remote sensing reflectance of oligo- to mesotrophic lakes

Alfred Johny Wüest, Damien Bouffard, Vincent Maurice Nouchi

We investigate the impact on remote sensing reflectance by the vertical non-uniformities of water constituents. Reflectance simulated for 210 pairs of in situ measured chlorophyll-a and turbidity profiles (z = 0–20 m) from Lake Geneva are compared to simul ...

Toward a systematic integration of optical remote sensing for inland waters studies

Vincent Maurice Nouchi

Freshwater resources play a central role in social and economic development of modern civilisations, yet their value is often underestimated and neglected in developed countries. In fact, freshwater habitats are facing unprecedented threat because of human ...

Airborne hyperspectral sensor radiometric self-calibration using near-infrared properties of deep water and vegetation

Bertrand Merminod, Kevin Sylvain Barbieux, Vincent Maurice Nouchi

Retrieving the water-leaving reflectance from airborne hyperspectral data implies to deal with three steps. Firstly, the radiance recorded by an airborne sensor comes from several sources: the real radiance of the object, the atmospheric scattering, sky an ...

Leman-Baikal: Remote sensing of lakes using an ultralight plane

Ulrich Lemmin, Bertrand Merminod, Natacha Tofield-Pasche, Damien Bouffard, Yosef Akhtman, Dragos Constantin, Martin Rehak, Vincent Maurice Nouchi, Galina Shinkareva

The Leman-Baikal project constitutes an international Swiss-Russian collaborative research initiative in the field of physical limnology. The three-year framework involves the development and deployment of a novel multispectral and hyperspectral remote sen ...
