Possibilities to move Towards consistent assessments of in situ radiometric measurements for the validation of fluorescence satellite missions were published in Remote Sensing of Environment by Bastian Buman with contributions from Alexander Damm. The paper outlines strategies to evaluate the accuracy of in situ FloX measurements from the radiance measurement to the retrieved fluorescence product.
RSWS participated at ESA's Living Planet Symposium 2022 and contributes to 11 presentations. Among them Remika Gupana presented her work on Quantum yield estimates from in situ spectroradiometer measurements and its implications on remote sensing of sun-induced fluorescence in lakes. Joan Sturm presented her work on Topography and stand characteristics controlled forest response to the 2018 drought in Switzerland.

The Swiss Remote Sensing Days were held the first time at Monte Verità. The workshop was initialized by the Swiss Commission on Remote Sensing (scnat) to network among the Swiss remote sensing community and discuss ongoing and future activities. The event was a large success! A big thank you to the main organizer Devis Tuja and the co-organizers Konrad Schindler and Alexander Damm and our various sponsors!!

A new paper on Mapping the spatial distribution of NO2 with in situ and remote sensing instruments during the Munich NO2 imaging campaign was published in Atmospheric Measurement Techniques by Gerrit Kuhlmann with contributions from Alexander Damm. The paper provides insights on the potential of the airborne imaging spectrometer APEX to measure vertical column densities of atmospheric trace gas NO2.

A new paper on Response times of remote sensing measured sun-induced chlorophyll fluorescence, surface temperature and vegetation indices to evolving soil water limitation in a crop canopy was published in Remote Sensing of Environment by Alexander Damm with contributions from Joan Sturm. We found a double response of SIF in relation to evolving water limitation and investigate temporal sensitivity of various remote sensing proxies for crop water limitation.

A new paper on impacts from the 2018 extreme summer drought event on Swiss forest ecosystems and the environmental variables influencing differing responses in drought resistance, recovery, and resilience has been published in Global Change Biology by Joan Sturm, Maria J. Santos, Bernhard Schmid, and Alexander Damm. Forests in close proximity to the forest edge, on southern facing slopes and at low elevations were found to have the lowest drought resistance but high recovery. Whereas, coniferous trees were attributed with the lowest resilience values.

A new contribution on Fractal geometry and the downscaling of sun-induced chlorophyll fluorescence imagery was published in the Encyclopedia of Earth Sciences Series by Juan Quiros-Vargas with contributions from Alexander Damm. The book chapter suggests a new possible strategy to assess sub-pixel process dynamics of fluorescence measured with large scale satellite data.

A new paper on Combining near-infrared radiance of vegetation and fluorescence spectroscopy to detect effects of abiotic changes and stresses with contributions by Alex Damm was published in Remote Sensing of Environment. This study suggests a new NIRv based strategy to normalize structural effects in sun-induced chlorophyll fluorescence and demonstrates resulting increaed sensitivity to detect plant stress due to various abiotic factors.

We warmly welcome Jennifer Adams as joint Postdoctoral researcher between the Remote Sensing group and us. Jennifer will work on 3D modelling of thermal radiation in support of the upcoming French-Indian TRISHNA satellite mission. In addition, Jennifer will investigate possibilities to harmonize radiative transfer schemes for aquatic and terrestrial applications.
