Observations and fieldwork
Observation towers support long-term measurements of wind speed, wind direction and humidity, complemented by instrumented fixed-wing UAVs. Fieldwork involved tower construction and maintenance, instrument deployment and UAV assembly and operation. The related publication examines large-scale eddies in the surface layer of the Loess Plateau.

Fieldwork in 2019–2021 and 2024 involved construction and maintenance of observation towers across the Loess Plateau, supporting long-term records of wind speed and direction, humidity and ground evaporation. Multi-site observations support studies of atmospheric turbulence and the applicability of ergodicity assumptions in its measurement.

Fixed-wing UAV observations (2019)
Instrumented fixed-wing UAVs supported atmospheric observations over the ravine-dissected terrain of the Loess Plateau. Xiaowen Chen assembled and operated the aircraft to provide measurements complementary to the ground-based observations.
