Figure S10 Response of
gross primary productivity to inter-product diffuse fraction spread for
2030-2039 period. Associations between gross primary productivity (GPP)
and diffuse fraction (k d) across different land
model simulations forced using k d from the six
products (NCEP/NCAR, NOAA-CIRES-DOE, ERA5, MERRA-2, CERES, and CAM)
considered in the present study for (a) all terrestrial surfaces, (b)
tropical climate, (c) arid climate, (d) temperate climate, (e) boreal
climate, and (f) polar climate for the 2030-2039 10-year period. The
lines of best fit and the linear regression equations, with coefficient
of determination r 2 and p-values are noted. For
tropical and temperate climate, logarithmic fits and associated
equations are also noted (in red). The vertical error bars show the
inter-annual standard error for the 10-year period.
