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).

Soy bean measurement campaign started


Yesterday, Katharina, Felix and Albin headed down to near Udine to set up the QCLAS in a measurement campaign comparing the energy balance and CO2 exchange of the wild type soy bean (dark green to the left) with a bright high-albedo mutant (minngold; to the right).


Below some further impressions.
