Flux towers #4 and 5 operational! On 25 May 2012, Albin and Georg set up two urban flux towers in Bolzano/Bozen. These will measure latent and sensible heat fluxes within the frame of the Cooling town project. in particular we are interested in quantifying the degree to which plant-covered surfaces in urban areas are able to affect the partitioning between sensible and latent heat fluxes. Now all our turbulence equipment is somewhere out in the field – thanks to Mathias Rotach for lending us two krypton hygrometers!
