Eddy Covariance measurements at Hartheim Research Forest Site (DE-Har) from 2021-01-01 to 2021-12-31 [RAW]

Original raw high-frequency eddy covariance data and on-site processed turbulent fluxes for the year 2021 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: Christen, A., Baab, F., Kolbe, S., Plapp, T., Redepenning, D., Schindler, D. (2025).

Use with caution. The orginical high-freuqency (20 Hz) data are available as LICOR .ghg files packaged in monthly tarball archives (e.g. 2021-01.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-2021.csv") Note: All times (both ghg and Summary) are provided in UTC, not local time.
