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).
