1. Remote sensing phenology at European northern latitudes - From ground spectral towers to satellites
Abstract : Plant phenology exerts major influences on carbon, water, and energy exchanges between atmosphere and ecosystems, provides feedbacks to climate, and affects ecosystem functioning and services. Great efforts have been spent in studying plant phenology over the past decades, but there are still large uncertainties and disputations in phenology estimation, trends, and its climate sensitivities.

2. Colorimetric and Multispectral Image Acquisition
Abstract : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

3. Fourier transform and Vernier spectroscopy using optical frequency combs
Abstract : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

4. Lifetime Surface Phosphor Thermometry - Technique Developments, Sources of Error, and Applications
Abstract : Temperature is not only a fundamental aspect of everyday life, but it is also an essential metric for thermal conversion systems concerning efficiency, emissions, and component lifetime estimation. Therefore, a vast range of different methods to measure temperature has been developed. READ MORE
