Figure S9 Response of sensible heat flux from ground to inter-product diffuse fraction spread. Associations between sensible heat flux from ground and diffuse fraction (k d) across different land model simulations forced usingk 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.
