Comment: urban ecosystem fluxes calculated by EddyPro 7.0.9, gapfilling by REddyProc online gapfilling tool (MPI Jena, https://www.bgc-jena.mpg.de/5622399/REddyProc). Timestamp at the end of averaging interval. Flux measurement height: 39.75m a.g.l., since 2022-07 40.25 m. Variables: TIMESTAMP (time instant, UTC), date (measurement date), time (measurement time, UTC), H_1_1_1 (sensible heat flux, Wm-2), LE_1_1_1 (latent heat flux, Wm-2), Fc_1_1_1 (carbon dioxide (CO2) flux, umolm-2s-1), Ustar_1_1_1 (friction velocity, ms-1), WS_1_1_1 (wind speed, ms-1), WD_1_1_1 (wind direction, degrees from N), NEE_1_1_1 (gap-filled net ecosystem exchange umolm-2s-1), LE_f_1_1_1 (gap-filled latent heat flux, Wm-2), H_f_1_1_1 (gap-filled sensible heat flux, Wm-2).
