Hysteresis of the gross primary production (GPP) diel cycle predicted by NN_C‐part with respect to SW_IN in three sampled study sites (a–c). Three different International Geosphere–Biosphere Programme classes are reported: DBF (a), ENF (b), and GRA (c), while the period of interest was July–August. (d) Distribution of the GPP hysteresis integral area (then normalized) estimated by NN_C‐part, nighttime method (NT), and daytime method (DT) partitioning methods. The hysteresis of the diel cycle of ecosystem respiration (RECO; here log‐transformed) with respect to the TA dynamic, in three sampled study sites, is reported (e–g). The distribution of the RECO hysteresis integral area (then normalized) estimated by NN_C‐part, NT, and DT partitioning methods is reported (h)
