[1] This study presents the first comparison of seasonal groundwater storage (GWS) variations derived fromGRACE satellite data with groundwater-level measurements in the High Plains Aquifer, USA (450,000 km). Correlation between seasonal GRACE terrestrial water storage (TWS) and the sum of GWS estimated from field measurements (2,700 wells) and soil moisture (SM) simulated by a land surface mod...

the highest temperatures of the world are recorded in dry and warm climates. this can especially be observed in deserts, where vegetations and soil moisture are very low. as a result, the soil surface receives high thermal energy and its temperature rises up. the lut desert has the above characteristics, making it a suitable environment to prepare land surface temperature (lst) models. objectiv...

General circulation models (GCMs) are valuable tools for understanding how the global ocean–atmosphere– land surface system interacts and are routinely evaluated relative to observational data sets. Conversely, observational data sets can also be used to constrain GCMs in order to identify systematic errors in their simulated climates. One such example is to prescribe sea surface temperatures (...

A generalization of the single soil layer variable infiltration capacity (VIC) land surface hydrological model previously implemented in the Geophysical Fluid Dynamics Laboratory general circulation model (GClVO is described. The new model is comprised of a two-layer characterization of the soil column, and uses an aerodynamic representation of the latent and sensible heat fluxes at the land su...

We study the response of the land-surface to prescribed atmospheric forcing for 31 May 1978 at Cabauw, Netherlands, using the land-surface scheme from the Coupled Atmospheric boundary layer-Plant-Soil (CAPS) model. Results from model runs show realistic daytime surface fluxes are produced using a canopy conductance formulation derived from Cabauw data (for 1987, a different year), and un-tuned ...

the use of satellite data in an estimation of air temperature (ta) near the earth’s surface has turned into an effective way for a large area of high spatial and temporal resolution. throughout the present study, artificial neural network (ann) as well as m5 model tree were employed to estimate ta in khuzestan province (south west of iran), using satellite remotely sensed land surface temperatu...

Land surface characteristics play a critical role in the evolution of the planetary boundary layer of the atmosphere. Several key components of the land surface that significantly affect surface sensible heat and moisture fluxes include soil temperature and moisture, fractional vegetation coverage (σf ), and green leaf area index (LAI). The lack of observational data for accurate specification ...

ABSTRACT- One of the big problems today human societies are faced with is the problem of soil erosion. In this study, the "MPSIAC model" was used to estimate sediment yield and provide sediment yield map in Cachoyeh watershed. The MPSIAC method incorporates nine environmental factors that contribute to sediment yield of the watershed. These factors are: surface geology, soil, climate, runoff, t...
