Interactions between dry-air entrainment, surface evaporation and convective boundary-layer development [PDF]
, 2009 The influence of dry-air entrainment on surface heat fluxes and the convective boundary-layer (CBL) properties is studied for vegetated land surfaces, using a mixed-layer CBL model coupled to the Penman¿Monteith equation under a wide range of conditions.

Advancing land surface model development with satellite-based Earth observations [PDF]
Hydrology and Earth System Sciences, 2017 The land surface forms an essential part of the climate system. It interacts with the atmosphere through the exchange of water and energy and hence influences weather and climate, as well as their predictability.

Investigating sources of uncertainty associated with the JULES land surface model [PDF]
, 2016 The land surface is a key component of the climate system and exchanges energy, water and carbon with the overlying atmosphere. It is the location of the terrestrial carbon sink and changes in the land surface can impact weather and climate at various

Remote Sensing, 2021 Land surface models (LSMs) simulate water and energy cycles at the atmosphere–soil interface, however, the physical processes in the subsurface are typically oversimplified and lateral water movement is neglected. Here, a cross-evaluation of land surface

Global GPP simulated by the JULES land surface model for 2001-2010 [PDF]
, 2016 This study evaluates the ability of the Joint UK Land Environment Simulator (JULES) Land Surface Model (LSM), the land surface scheme of the UK Met Office Unified Model (MetUM), to simulate Gross Primary Productivity (GPP) at regional and global scales

Land surface spinup for episodic modeling [PDF]
Atmospheric Chemistry and Physics, 2014 Abstract. Soil moisture strongly controls the surface fluxes in mesoscale numerical models, and thereby influences the boundary layer structure. Proper initialization of soil moisture is therefore critical for faithful simulations. In many applications, such as air quality or process studies, the model is run for short, discrete periods (a day to a ...

Relative Humidity as an Indicator for Cloud Formation over Heterogeneous land surfaces [PDF]
, 2008 The influence of land surface heterogeneity on potential cloud formation is investigated using relative humidity as an indicator. This is done by performing numerical experiments using a large-eddy simulation model (LES).

A flux tower dataset tailored for land model evaluation [PDF]
Earth System Science Data, 2022 Eddy covariance flux towers measure the exchange of water, energy, and carbon fluxes between the land and atmosphere. They have become invaluable for theory development and evaluating land models.

Land‐Surface‐Atmosphere Coupling in Observations and Models [PDF]
Journal of Advances in Modeling Earth Systems, 2009 The diurnal cycle and the daily mean at the land‐surface result from the coupling of many physical processes. The framework of this review is largely conceptual; looking for relationships and information in the coupling of processes in models and observations.

Evaluation of the Surface Energy Balance System (SEBS) applied to ASTER imagery with flux-measurements at the SPARC 2004 site (Barrax, Spain) [PDF]
, 2009 Accurate quantification of the amount and spatial variation of evapotranspiration is important in a wide range of disciplines. Remote sensing based surface energy balance models have been developed to estimate turbulent surface energy fluxes at different
