Assessment of atmospheric emissivity models for clear-sky conditions with reanalysis data.

ABSTRACT: Atmospheric longwave downward radiation (L_d) is one of the significant components of net radiation (R_n), and it drives several essential ecosystem processes. L_d can be estimated with simple empirical methods using atmospheric emissivity (ε_a) submodels. In this study, eight global models for ε_a were evaluated, and the best-performing model was calibrated on a global scale using a parametric instability analysis approach. The climatic data were obtained from a dynamically consistent scale resolution of basic atmospheric quantities and computed parameters known as NCEP/NCAR reanalysis (NNR) data. The performance model was evaluated with monthly average values from the NNR data. The Brutsaert equation demonstrated the best performance, and
