Measurement campaign in Mezyk/Poland

Last week, Karolina, Michaela and Albin, went up to Mezyk/Poland to set up the instrumentation for a joint COS/CO2 flux and chlorophyll fluorescence campaign over a Scots Pine forest. The idea of the campaign is to quantify GPP during the “spring awakening” of photosynthesis of this evergreen species and use active and passiv chlorophyll fluorescence to diagnose functioning of the electron transport chain and evaluate the potential of sun-induced chlorophyll fluorescence as a proxy for GPP.

Hyperspectral and SIF measurements starting at Neustift

Today Karolina and others mounted the WhiteRef loaned from FEM (foreground) and our SIF system (background) to start jointly measuring hyperspectral reflectance and passive (sun-induced) fluorescence at Neustift within the frame of her Marie Sklodowska-Curie project COSIF. These measurements will be accompanied within COS/CO2 eddy covariance flux measurements and active chlorophyll fluorescence by means of a moniPAM.

Advection measurement campaign at Torgnon

Beginning of July, Peng and Katharina, assisted by Marta and other ARPA staff, set up the advection equipment at the Torgnon grassland site for an extended campaign. Due to the difficult site access, our equipment was delivered by a helicopter, which created much excitement. The first picture has been taken by a drone and shows the present setup and the setup of the 2017 paper (red line) and the position of the permanent eddy flux tower (red circle).
