Soil moisture is a key driver of many meteorological, hydrological and climatological processes. Satellite remote sensing using radar sensors facilitates its global monitoring and depicts valuable input to meteorological models, agricultural management and flood prediction. However, a single spaceborne sensor cannot deliver information in both, high spatial and temporal detail. The SCATSAR-SWI ...

In traditional principal component analysis (PCA) a few significant linear combinations of the original variables are extracted to arrive at a parsimonious description of a complex. data set obtained from climate observations, analysis or from GCM ouputs. These are uncorrelated variables which are used in practice to understand the principal modes of variation in the climatological process unde...

Ensemble Kalman filters are developed for turbulent dynamical systems where the forecast model does not resolve all the active scales of motion. These filters are based on the assumption that a coarse-resolution model is intended to predict the large-scale part of the true dynamics; since observations invariably include contributions from both the resolved large scales and the unresolved small ...

Dual frequency ground based microwave radiometers (MWR) are widely used to measure precipitable water vapor (PWV) and integrated cloud liquid water (ICL). In the statistical retrieval method, where the relationship between measured brightness temperature (Tb) and opacity ( ) is used, an accurate statistical retrieval algorithm is required. These algorithms include a set of input parameters whos...

The availability of global gridded precipitation and outgoing long-wave radiation (OLR) data after 1978 makes possible an investigation of the influence of the decadal solar oscillation in the tropics during three solar maxima and two solar minima. The NCEP/NCAR reanalyses starting in the 1950s allows the inclusion of an additional two solar maxima and minima to look for consistency of response...

The present study deals with the implementation of an eddy resolving model of the Levantine and Aegean basins and its one-way nesting with a coarse resolution (1/8× 1/8) global Mediterranean general circulation model. The modelling effort is done within the framework of the Mediterranean Forecasting System Pilot Project as an initiative towards real-time forecasting within the eastern Mediterra...
