UK observations data collection of ground-based in situ, remote sensing and aircraft measurements across various sites in the European Alps during the TEAMx (Multi-scale Transport and Exchange processes in the Atmosphere over Mountains – programme and eXperiment) Observational Campaign (TOC) 2004-2005.

The data include measurements from target areas in the Inn Valley (Austria), the Adige Valley (Italy), the Alpine Crest between these two, and the Alpine Foreland in Germany. This took place from September 2024 to September 2025 with two Extensive Observation Periods (EOPs), one in winter (20 January – 28 February 2025 ) and one in summer (16 June – 25 July 2025)

This collections includes data from :
- In-situ airborne observations by the FAAM BAE-146 aircraft for TEAMxUK.
- remote sensing from NCAS X-band radar
- suite of NCAS surface instrumentation

TEAMx (TEAMx) was an international research programme that aimed at improving our understanding of exchange processes in the atmosphere over mountains and at evaluating how well these are represented in NWP and climate models.
