Figure S5 Response of Bowen ratio to inter-product diffuse
fraction spread. Associations between Bowen ratio 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) arid climate, (b) temperate climate, (c) boreal climate,
and (d) polar climate. The lines of best fit and the linear regression
equations, with coefficient of determination r 2and p-values are noted. The vertical error bars show the inter-annual
standard error for the 10-year period.
