Land surface processes and energy balance
Webb23 sep. 2024 · In theory, changing the energy balance process can bring the same or more significant climate effects, such as land use change which can bring biophysical changes (albedo) directly, as well as effective net radiation, which includes sensible heat flux, latent heat flux (LHF) and surface heat flux. WebbThe simulation accuracy of land surface temperature and surface energy balance in arid and semiarid areas was improved via an improved heat roughness parameterization scheme in Noah. The sensible heat flux was also effectively improved in the CoLM model by adopting an independent method to determine aerodynamic roughness length.

Some is returned as long-wave (infrared) radiation, heating the atmosphere as the land surface warms. Some serves to evaporate water, either in the soil or in the leaves of plants, bringing water back into the atmosphere.
WebbLand surface models (LSMs) are pushing towards improved realism owing to an increasing number of observations at the local scale, constantly improving satellite data sets and the associated methodologies to best exploit such data, improved computing resources, and in response to the user community.
