The identification of a solar signal in climate records of the last 500 years using proxy and model-based analysis and the implications for natural climate variability
Satellite instruments car the solar constant solar energy output climate the climate warming
2014/10/22
There has been confirmation in the last two decades, through instrumental measurements onboard satellites, that the 'solar constant' does, as has long been hypothesized, vary. While there is no consen...
A model-based assessment of the potential role of irrigated cropland for biogas production in Europe
irrigated cropland biogas production Europe
2010/2/3
For the European Union, the increasing use of renewable energy sources is an important instrument to reduce its greenhouse gas emissions and to achieve greater independency from energy imports. Here, ...
EnKF assimilation of simulated spaceborne Doppler observations of vertical velocity: impact on the simulation of a supercell thunderstorm and implications for model-based retrievals
EnKF velocity
2010/1/27
Recently, a number of investigations have been made that point to the robust effectiveness of the Ensemble Kalman Filter (EnKF) in convective-scale data assimilation. These studies have focused on the...
Sensitivity analysis of a wetland methane emission model based on temperate and arctic wetland sites
a wetland methane emission model temperate and arctic wetland sites
2010/1/21
Modelling of wetland CH4 fluxes using wetland soil emission models is used to determine the size of this natural source of CH4 emission on local to global scale. Most process models of CH4 formation a...
Model-based scenarios of Mediterranean droughts
Model-based scenarios Mediterranean droughts
2010/1/27
This study examines the change in current 100-year hydrological drought frequencies in the Mediterranean in comparison to the 2070s as simulated by the global model WaterGAP. The analysis considers so...
Iron profiles and speciation of the upper water column at the Bermuda Atlantic Time-series Study site:a model based sensitivity study
Iron profiles speciation upper water column Bermuda Atlantic Time-series Study
2010/1/14
A one-dimensional model of the biogeochemistry and speciation of iron is coupled with the General Ocean Turbulence Model (GOTM) and a NPZD-type ecosystem model. The model is able to simulate the tempo...
Identification and model based assessment of the potential water retention caused by land-use changes
the potential water retention land-use changes
2010/1/27
The extreme summer flood in the Elbe River watershed initiated a debate on the role of forest conversion and afforestation as measures for preventive flood protection. To quantify the effect of forest...
Model based distributed water balance monitoring of the White Volta catchment in West Africa through coupled meteorological-hydrological simulations
distributed water balance the White Volta catchment West Africa coupled meteorological-hydrological simulations
2010/1/26
Sustainable water management requires the quantification of the spatial and temporal changes of water balance variables. Fully distributed hydrological simulations of these variables are especially in...
Model-based iterative approach to polarimetric radar rainfall estimation in presence of path attenuation
Model-based iterative approach polarimetric radar rainfall estimation path attenuation
2010/1/22
A new model-based iterative technique to correct for attenuation and differential attenuation and retrieve rain rate, based on a neural-network scheme and a differential phase constraint, is presented...
