As part of the activities of the TEAMx sub working group on glaciers, the second iteration of the HinterEisFerner EXperiment (HEFEX II) was carried out on Hintereisferner during the summer of 2023. This collaborative endeavor, involving twelve institutions from Austria, France, Germany, Switzerland, and the UK, yielded an unprecedented set of observations of glacier microclimate and turbulence structure. The on-glacier instrumentation consisted of eight 3m and two 5m weather stations equipped with multilevel eddy covariance systems and auxiliary instrumentation to capture vertical gradients in atmospheric properties and processes above the glacier surface, and eight additional lower specification weather stations to capture spatial variability along the glacier centerline. These operated successfully for 4 weeks with minimal datagaps. During a 3 day intensive observational period, additional instrumentation was deployed to map the full vertical extent of the valley atmosphere: short-path ultrasonic anemometers installed very close to the glacier surface, thermal imaging of the boundary layer heat transport, a targeted 3D sampling of the glacier boundary layer using two meteorological UAVs, and a StreamLine XR Doppler LiDAR capturing the structure of the above-valley atmosphere. Here we describe the experimental set up, show a sample of preliminary results and discuss the outlook for future analyses.
