Soil moisture predictability and the associated predictability of continental climate are explored as an initialvalue problem, using a coupled land–atmosphere model with prescribed ocean surface temperatures. Ensemble simulations are designed to assess the extent to which initial soil moisture fields explain variance of future predictands (soil moisture, near-surface air temperature, and precip...

Soil moisture condition is one of the key parameters in environmental and agricultural modeling. In this paper, a modified triangle method (Ts/VI space) is suggested. Both NDVI and EVI are used in constructing the space. Based on this method we calculated the Temperature-Vegetation Dryness Index (TVDI) using 20 MODIS images (Land surface temperature and vegetation index products) to estimate th...

For more than a decade, the European Centre for Medium-Range Weather Forecasts (ECMWF) has used in-situ observations of 2 m temperature and 2 m relative humidity to operationally constrain the temporal evolution of model soil moisture. These observations are not available everywhere and they are indirectly linked to the state of the surface, so under various circumstances, such as weak radiativ...

The soil moisture content is of great importance for numerical weather forecasts and has been identified as one of the parameter products of EUMETSAT’s Satellite Application Facility on Land Surface Analysis (Land SAF). Soil moisture strongly affects the surface energy balance and therefore near surface temperature and humidity. Conversely, temperature observations may be used to infer the soil...

introduction growing use of hydrocarbon constituents in various industries have generated significant quantities of hazardous wastes which lead to environmental pollution. in recent years, the strong global demands for fossil fuels and industrial chemicals have resulted in the release of some of these compounds into soil, water and air.hydrocarbon-contaminated soils are among the important envi...

A review of recent developments related to soil hydraulic property estimation using remote sensing is presented. Several soil hydraulic parameter estimation techniques using proximal-, air-, or satellite-based remotely sensed soil moisture, land surface temperature, and/ or evapotranspiration time series have evolved over the past decades. In particular, microwave remote sensing of near-surface...

The Soil Moisture and Ocean Salinity (SMOS) mission will provide L-Band multi-angular measurements of the surface emission with a 2-D interferometric radiometer on a global basis [1]. Soil moisture will be retrieved from collected and simulated data using a minimization algorithm. The success of the process will partly depend on how accurate is the modelling of the surface radiation and the cor...
