Eddy Covariance measurements at Hartheim Research Forest Site (DE-Har) from 2023-01-01 to 2023-12-31 [RAW]

Original raw high-frequency eddy covariance data and on-site processed turbulent fluxes for the year 2023 from above the forest canopy at Hartheim Forest Research Site (ICOS Associate Ecosystem Site DE-Har, UFR Code: HARTHM, 7.59814ºE, 47.93391ºN, 201 m). The eddy covariance system was operated at 29 m on the site's main 30 m tower facing west using an CSAT3 ultrasonic anemometer and a Licor Inc. Li-7200RS enclosed-path analyzer connected to a SmartFlux system running Eddy Pro from Licor Inc. in Express Mode. For final processed and quality-controlled fluxes, please download the official ICOS data available for DE-Har through the ICOS Carbon Portal and please cite the original ICOS dataset. This repository only provides the underlying raw unchecked, unfiltered and original data from the DE-Har system not available above for purposes of documentation and future reprocessing. Use with caution. The orginical high-freuqency (20 Hz) data are available as LICOR .ghg files packaged in monthly tarball archives (e.g. 2023-01.tar contains all .ghg files of the SmartFlux system for the month of January) The processed fluxes from the on-site system are available in one combined annual summary file "DE-Har-SmartFlux-Combined-2023.csv") Note: All times (both ghg and Summary) are provided in UTC, not local time. Specific notes on the 2023 dataset: This dataset is used in the following scientific publications: Haberstroh S, Christen A, Sulzer M, Scarpa F, Werner C, 2025: Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest. Plant Biol J. Haberstroh S, Werner C, Grün M, Kreuzwieser J, Seifert T, Schindler D, Christen A, 2022: Central European 2018 hot drought shifts Scots Pine forest to its tipping point. Plant Biology, 24, 1186-1197.
