Abstract

A force-restore model (FRM) for predicting near-surface air temperature with sensible heat flux parameterized using the maximum-entropy-production (MEP) model, referred to as the FRMEP model, was formulated. The FRMEP model forced by net radiation is independent of wind speed, surface roughness lengths and temperature gradient. The FRMEP model is able to simulate accurately the diurnal and seasonal variations of near-surface air temperature and sensible heat flux using less input data and model parameters than other models. The FRMEP model was evaluated using field observations with contrasting climate and soil wetness conditions. The proposed FRMEP model of air temperature provides an alternative and effective modeling tool for the study of coupled land-vegetation-atmospheric systems.
