TEAMx (Multi-scale transport and exchange processes in the atmosphere over mountains – programme and experiment) is an international research program that focuses on improving our understanding of atmospheric transport and exchange processes over complex terrain and at evaluating and improving the representation of these processes in numerical weather and climate prediction models. One pillar of the TEAMx program is a one-year long observational campaign to collect a unique dataset that can be used to address the research goals. The TEAMx Observational Campaign (TOC) started in September 2024, with observational activities taking place in four target areas arranged in an approximate north-south transect trough the Alps. In addition to long-term monitoring using continuous measurements at multiple locations throughout the entire TOC, two six-week long extensive observational periods (EOPs) were conducted. The two EOPs, one in winter (wEOP) and one in summer (sEOP), were designed to target specific processes, with a high density of observations at individual supersites located in the TEAMx domain. The activities focused on, for example, the mean and turbulence characteristics of katabatic and anabatic winds, the three-dimensional structure of the mountain boundary layer at different spatial scales, the initiation and development of orographic convection, and the structure of gravity waves. To address these research topics, a suite of observational tools was applied, including research flights with three aircraft, radiosonde launches from multiple locations, UAS flights, a range of different remote-sensing instrumentation to capture the vertical wind and temperature profiles throughout the TEAMx domain, and networks of weather and turbulence stations. In addition, the observational activities were supported by dedicated high-resolution forecast runs from several European weather services to provide guidance for daily IOP decisions. The presentation will give an overview of the research goals for the TOC, its design and observational activities, and some first and preliminary findings.
