英文摘要Distinguishing gross primary production of sunlit and shaded leaves (GPP(sun) and GPP(shade)) is crucial for improving our understanding of the underlying mechanisms regulating long-term GPP variations. Here we produce a global 0.05 degrees, 8-day dataset for GPP, GPP(shade) and GPP(sun) over 1992-2020 using an updated two-leaf light use efficiency model (TL-LUE), which is driven by the GLOBMAP leaf area index, CRUJRA meteorology, and ESA-CCI land cover. Our products estimate the mean annual totals of global GPP, GPP(sun), and GPP(shade) over 1992-2020 at 125.0 +/- 3.8 (mean +/- std) Pg C a(-1), 50.5 +/- 1.2 Pg C a(-1), and 74.5 +/- 2.6 Pg C a(-1), respectively, in which EBF (evergreen broadleaf forest) and CRO (crops) contribute more than half of the totals. They show clear increasing trends over time, in which the trend of GPP (also GPP(sun) and GPP(shade)) for CRO is distinctively greatest, and that for DBF (deciduous broadleaf forest) is relatively large and GPP(shade) overwhelmingly outweighs GPP(sun). This new dataset advances our in-depth understanding of large-scale carbon cycle processes and dynamics.
