Zurich-Hardau Flux Footprints

A collection of flux footprints for the Zurich-Hardau flux tower in Switzerland at 30-minute temporal resolution from the period 2022-07-13 to 2024-12-12. Each dataset contains up to 48 footprints with the following variables each: Time, X, Y, Boundary Layer Height Quality Flag, and Footprint Climatology. The flux footprints are computed using FFP as described in Kljun et al. (2015), https://doi.org/10.5194/gmd-8-3695-2015, at 10-meter spatial resolution using ETC L2 Fluxes from Zurich-Hardau, https://hdl.handle.net/11676/Lg2RRHAdsLee0lsF-9KsTC-r. The projection can be customized, but the footprints were calculated in UTM 32N. This work is part of the ICOS Cities/PAUL Pilot Applications in Urban Landscapes project.
