Figure S2 Response of ecosystem respiration to inter-product
diffuse fraction spread. Associations between ecosystem respiration (ER)
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. The lines of best fit and the linear
regression equations, with coefficient of
determination r 2 and p-values are noted. The
vertical error bars show the inter-annual standard error for the 10-year
period.
