Deficiency and inappropriate distribution of reengage station is one of challenges faced by researchers in hydrology and climate science. In this research, evaluate the applicability of four gridded precipitation data products ERA-Interim, PERSIANN-CDR, PERSIANN-CCS and CRU as a supplement or substitute for ground data in a monthly time scales. This assessment was done by comparison with observ...

Based on marine environmental factors of different sea areas, a high-performance clutter time series modeling algorithm for the real surface is developed to study amplitude mean and Doppler spectrum characteristics clutter. The European Centre Medium-Range Weather Forecasts (ECMWF) data set (ERA-Interim) ESA’s soil moisture ocean salinity (SMOS) are utilized establish databases factors. Combine...

As we know, climate change and variability significantly influence the most important component of global hydrological cycle, i.e., rainfall. The study pertaining to in spatio-temporal patterns rainfall dynamics is crucial take appropriate actions for managing water resources at regional level prepare extreme events such as floods droughts. Therefore, our has investigated distribution performan...

The new radiation-transfer scheme RRTM is described in the article on page 2.The new scheme includes the representation of sixteen spectral bands, compared with six bands in the previous operational scheme.This allows improvements in the spectral description of the radiative properties of both the earth’s surface and the clouds.Tests of the impact of the scheme indicate improved anomaly correla...

Operational wave data assimilation at ECMWF started with ERS-1 radar altimeter wave heights on 15 August 1993. This had a significant impact on the wave model analysis and forecast. The impact of wave data assimilation based on the ECMWF experience is presented. This includes the impact of assimilation of ERS radar altimeter and synthetic aperture radar and ENVISAT radar altimeter-2 wave data. ...

In this paper we present the characterization of all the principal meteorological parameters (wind speed and direction, pressure, absolute and potential temperature) extended up to 25 km from the ground and over two years (2003 and 2004) above the Antarctic site of Dome C. The data set is composed by ’analyses’ provided by the General Circulation Model (GCM) of the European Center for Medium We...

The SMOSMANIA soil moisture network in Southwestern France is used to evaluate modelled and remotely sensed soil moisture products. The surface soil moisture (SSM) measured in situ at 5 cm permits to evaluate SSM from the SIM operational hydrometeorological model of Météo-France and to perform a cross-evaluation of the normalised SSM estimates derived from coarse-resolution (25 km) active micro...
