TEAMx: Microwave radiometer data (RPG HATPRO-G5), Radfeld, Austria

Overview As part of the TEAMx campaign, an RPG HATPRO-G5 microwave radiometer (MWR) was deployed in Radfeld (Inn Valley Target Area, IVTA), Austria, from 12 June 2025 to 8 September 2025. This repository provides the dataset collected during this deployment. More information on TEAMx can be found here. Microwave radiometer: RPG HATPRO-G5Location: 47.458999, 11.932239 (Radfeld, Austria)Altitude: 510 m a.s.l.Time period: 12 June 2025 to 8 September 2025 Owner: Federal Office of Meteorology and Climatology MeteoSwiss, SwitzerlandContact: Rebecca Gugerli, Maxime Hervo This campaign was meant to run for about a year. However, the first MWR deployed at the site (RPG HATPRO-G2) in October 2024 exhibited poor data quality. Therefore, only data from the newer microwave radiometer (G5), deployed on 21 May 2025, are provided. Although the instrument was installed in May, data are only available from 12 June 2025 onward because the MWR could not be calibrated before that date due to logistical challenges. The instrument remained operational until it was dismantled on 8 September 2025. If you have any questions about the dataset, please do not hesitate to contact us.

We would like to thank the Klärwerk in Radfeld for allowing us to deploy the instrument on their premises. We also thank the remote-sensing technical (Philipp Bättig, Daniel Bugnon and Ludovic Renaud) and administrative (Valérie Brulhart) team at MeteoSwiss for preparing (incl. custom documents), deploying, and dismantling the instrument. Last but not least, we thank Beth Saunders, Philipp Vettori, and Alexander Gohm from the University of Innsbruck for their support during the deployment and on-site calibration.
