Modeling Surface Energy Fluxes over a Dehesa (Oak Savanna) Ecosystem Using a Thermal Based Two-Source Energy Balance Model (TSEB) I
Savannas are among the most variable, complex and extensive biomes on Earth, supporting livestock and rural livelihoods. These water-limited ecosystems are highly sensitive to changes in both climatic conditions, and land-use/management practices. The integration of Earth Observation (EO) data into process-based land models enables monitoring ecosystems status, improving its management and cons...
متن کاملModelling surface energy fluxes over maize using a two-source patch model and radiometric soil and canopy temperature observations
Models estimating surface energy fluxes over partial canopy cover with thermal remote sensing must account for significant differences between the radiometric temperatures and turbulent exchange rates associated with the soil and canopy components of the thermal pixel scene. Recent progress in separating soil and canopy temperatures from dual angle composite radiometric temperature measurements...
متن کاملModeling Newborn Piglet Thermal Interactions with a Surface Energy Balance Model
A mathematical model was developed to describe the radiative and convective thermal interactions between a newborn piglet and ifs surroundings. The model incorporates surface energy balances for each surface in the enclosure. The model was verified with results from a simulated creep area and from published calorimetric studies on newborn pigs. Mathematical results were all within 5.5% of the m...
متن کاملA Two-Source Time-Integrated Model for Estimating Surface Fluxes Using Thermal Infrared Remote Sensing
W e present an operational two-source (soil+vegetation) ,ugdel for evaluating the surface energy balance given measurements of the time rate of change in radiometric surface temperature (TRao) during the ~u~rning hours. This model consists of a two-source surface component describing the relation between T~o and sensible heat flux, coupled with a time-integrated component connecting surface sen...
متن کاملSimulating energy and carbon fluxes over winter wheat using coupled land surface and terrestrial ecosystem models
Coupled land surface and terrestrial ecosystem models are used to simulate energy and carbon fluxes over winter wheat at the Ponca City, Oklahoma, Ameriflux site. The terrestrial ecosystem model consists of photosynthesis and respiration (autotrophic and heterotrophic) sub-modules, which uses canopy temperature, soil moisture, and soil temperature simulated by the land surface scheme. The photo...
