Figure 1. Comparison of Reco data from Reco_2001_2010_data_set, from Jung et al. (2019) and site observations for major ecosystems; unit: gCm⁻²d⁻¹.

Figure 2. Seasonal Reco patterns from Reco_2001_2010_data_set (unit: gCm⁻²). Spring: March, April and May; Summer: June, July and August; Autumn: September, October and November; Winter: December, January and February. The largest seasonal change occurs in the northern hemisphere.

Figure 3. Annual ecosystem respiration patterns from Reco_2001_2010_data_set, from process model LPJ_S1 and from Jung et al. (2019) (unit: gCm⁻²a⁻¹); differences in annual ecosystem respiration patterns between Reco_2001_2010_data_set and Yuan et al. (Yuan et al., 2011) (Unit: gCm⁻²a⁻¹); differences in annual ecosystem respiration patterns between Reco_2001_2010_data_set and LPJ_S1 (Unit: gCm⁻²a⁻¹); differences in annual ecosystem respiration patterns between Reco_2001_2010_data_set and Jung et al. (Jung et al., 2019) (Unit: gCm⁻²a⁻¹).

Table 2. The difference between the annual total amount of Reco from Reco_2001_2010_data_set and the flux-measured data at the sites where the difference between the four data sets was the largest (The values in Reco_2001_2010_data_set were closer to the observations than those in the other three data sets (LPJ_S1, Yuan et al. (2011)) and Jung et al. (2019)) were.
