Contributions

W.L., R.O., and C.F. conceived the study concept. W.L., R.O., M.M., M.R., M.F., and C.F. developed the methods and designed the experiment. W.L. conducted data analyzes, visualized results, and wrote the manuscript with suggestions from R.O., D.M., and A.J.H.v.D. J.P.J conducted the SCOPE experiment with the suggestions from M.M. W.Z. contributed to eddy covariance data processing. A.P. derived the equation of the simplified surface energy balance model. U.W. contributed to a large part of pre-processing of observation-based datasets. W.L., R.O., and J.P.J. revised the manuscript based on critical comments from M.M., D.M., A.J.H.v.D., M.R., M.F., and P.G. throughout the manuscript. D.M., A.J.H.v.D., A.P., and Q.Z. contributed to text corrections and results interpretation.
