Impacts of Land-Atmosphere Interactions on Regional Convection and Rainfall
… simulating the interaction between the land surface and regional convection and rainfall is a source of uncertainties and presents three main barriers: (i) NWP models generally have simple land surface schemes, (ii) land-atmosphere coupling is not properly represented in models, and …

Investigation of the Influence of Temperature Inversions and Turbulence on Land-atmosphere Interactions for Rolling Terrain
The surface-atmosphere exchange of trace gases and energy is important as it impacts weather, climate, and air quality. The models used for estimating surface fluxes such as heat, moisture, and carbon dioxide (CO2) were designed to work best in horizontally uniform, flat terrain. This is a …

Estimating Soil Moisture and Energy Fluxes Using Assimilation of Remotely Sensed Land Surface State Variables
Soil moisture plays a critical role in the land-atmosphere interactions. Given the approximate model physics representation in the land surface models predicting these fluxes, better predictions can be obtained by assimilating hydrologically relevant remotely sensed data into the predictive models. …

Importance of boundary layer entrainment for surface fluxes over land
… impacts of entrainment in a coupled ecosystem-atmosphere model by implementing an enhanced entrainment parameterization based on the assumption that the heat flux at the top of the PBL is negatively proportional to the heat flux at the surface. This experiment found that entrainment produced a …

Isolating the observed influence of vegetation variability of La Plata River basin on the climate of South America
Land surface variability and change can affect the overlying atmosphere through biogeophysical and biogeochemical feedbacks. The goal of our work is to isolate and quantify the local and remote influences of vegetation on the climate of South America using observational records. We find that the …
