Materials Data on HoAgGe by Materials Project

HoAgGe crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ho is bonded in a 11-coordinate geometry to five Ag and six equivalent Ge atoms. There are one shorter (2.91 Å) and four longer (3.05 Å) Ho–Ag bond lengths. There are two shorter (3.21 Å) and four longer (3.29 Å) Ho–Ge bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent Ge atoms. All Ag–Ge bond lengths are 2.72 Å. In the second Ag site, Ag is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent Ge atoms. All Ag–Ge bond lengths are 2.85 Å. Ge is bonded in a distorted q6 geometry to six equivalent Ho and four Ag atoms.

University of Kentucky measurements of wind, temperature, pressure and humidity in support of LAPSE-RATE using multisite fixed-wing and rotorcraft unmanned aerial systems

In July 2018, unmanned aerial systems (UASs) were deployed to measure the properties of the lower atmosphere within the San Luis Valley, an elevated valley in Colorado, USA, as part of the Lower Atmospheric Profiling Studies at Elevation – a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE). Measurement objectives included detailing boundary layer transition, canyon cold-air drainage and convection initiation within the valley. Details of the contribution to LAPSE-RATE made by the University of Kentucky are provided here, which include measurements by seven different fixed-wing and rotorcraft UASs totaling over 178 flights with validated data. The data from these coordinated UAS flights consist of thermodynamic and kinematic variables (air temperature, humidity, pressure, wind speed and direction) and include vertical profiles up to 900 m above the ground level and horizontal transects up to 1500 m in length. These measurements have been quality controlled and are openly available in the Zenodo LAPSE-RATE community data repository (https://zenodo.org/communities/lapse-rate/, last access: 23 July 2020), with the University of Kentucky data available at https://doi.org/10.5281/zenodo.3701845 (Bailey et al., 2020).
