This trend could be attributed to the low OM content of the cultivated land and the subsurface soil depth and the increase in bulk density with soil depth, respectively.
Subsurface soil temperature is a key variable of land surface processes and not only responds to but also modulates the interactions of energy fluxes at the Earth's surface.
In this study, we present an efficient model calibration strategy, based on a hierarchy of grid resolutions, each of them resolving the same zonation of subsurface and land-surface units.
Controlling factors of nutrient export were discussed in this study, including season, hydrology (base flow, storm flow, surface and subsurface runoff), and land use.
Additional energy sink terms, including the heating of the atmosphere, the land subsurface, and the melting and heating of ice additionally contribute [ Trenberth and Fasullo, 2013], and simulations also indicate that substantial energy flux of ±0.1 Wm−2 across the 1800 m isobath are possible through internal variability alone [ Palmer and McNeall, 2014].
The authors describe the performance of a multi-sensor package designed to measure the electromagnetic properties of the subsurface during future landing missions to Mars.
Among the presently planned missions, the NETLANDER project offers a unique opportunity to explore simultaneously the deep interior of the planet and the first layers of the subsurface in 4 landing sites displaying different geophysical morphologies.
On the other hand, unlike to the cultivated and forest lands, the mean values of PBS was significantly reduced from 50.42 % in the surface (0 20 cm) soil to 42.60 % in the subsurface (20 40 cm) soil of the grazing land (Table 8).
A novel manifold method of reconstructing dynamically evolving spatial fields is presented for assimilating data from sensor networks in integrated land surface – subsurface, oceanic/lake models.
By decoupling the magnitude and sourcing of evapotranspiration, this study proposes a powerful diagnostic tool to evaluate the representation of subsurface hydrological processes in land surface models.
Evapotranspiration from the surface and subsurface are modeled using land cover and climatic factors to define the complete water budget using a physically-based formulation.
