This paper introduces and presents the Spatial Processes in HYdrology (SPHY) model (v2.0), its development background, its underlying concepts, and some example applications. SPHY has been developed w...
Development of PM2.5 source impact spatial fields using a hybrid source apportionment air quality model
PM2.5 source spatial fields hybrid source apportionment air quality model
2015/8/6
An integral part of air quality management is knowledge of the impact of pollutant sources on ambient concentrations of particulate matter (PM). There is also a growing desire to directly use source i...
A multiresolution spatial parameterization for the estimation of fossil-fuel carbon dioxide emissions via atmospheric inversions
multiresolution spatial parameterization estimation
2014/12/19
The characterization of fossil-fuel CO2 (ffCO2)
emissions is paramount to carbon cycle studies, but the use
of atmospheric inverse modeling approaches for this purpose has been limited by the highly...

Complex numerical models of the Earth’s environment, based around 3-D or 4-D time and space domains are
routinely used for applications including climate predictions,weather forecasts, fishery ...
Spatial Distribution of Seismicity: Relationships with Geomagnetic Z-Component in Geocentric Solar Magnetospheric Coordinate System
Earthquake Occurrence Earthquake Magnitude
2013/3/11
For 173477 epicenters of earthquakes with М ≥ 4.5, which occurred at the globe in 1973-2010, the geomagnetic Z-component in Geocentric Solar Magnetospheric (GSM) coordinate system were evaluated for t...
Spatial Variability of Selected Soil Properties in Relation to Different Land Uses in Northern Kgalagadi (Matsheng), Botswana
Kgalagadi Soils Land-Use Types Variation of Soil Properties

The characterization of temporal and spatial variability of soil moisture is highly relevant for understanding the many hydrological processes, to model the processes better and to apply them to conse...
Spatial variability and trends of the rain intensity over Greece
Spatial variability trends of the rain intensity
2010/9/10
In this study, the spatial and temporal variability of the mean annual rain intensity in Greece are examined during a 41-year period (1962–2002). The meteorological datasets concern monthly rain amoun...
Spatial relationships of heavy rains in the Czech Republic
Spatial relationships of heavy rains Czech Republic
2010/9/10
Study of heavy rain events and their spatial distribution are of great importance. Such events cause local flooding, accelerate soil erosion and cause damage on property. Data for this study were deri...
Impacts of spatial data resolution on simulated discharge, a case study of Xitiaoxi catchment in South China

In this paper we analyse the effects of different spatial input data resolution on water balance simulation using a simple distributed hydrological model: PCR-XAJ model. A data set consisting of land ...
Spatial characterization of raincell horizontal profiles from C-band radar measurements at mid-latitude
Spatial characterization raincell horizontal profiles
2010/1/27
A spatial characterization of mid-latitude mesoscale rain fields from C-band radar measurements is performed by means of a systematic analysis and modelling of convective raincell shapes. To this aim ...
A spatial resolution threshold of land cover in estimating terrestrial carbon sequestration in four counties in Georgia and Alabama, USA
land cover terrestrial carbon sequestration Georgia and Alabama, USA
2010/1/21
Changes in carbon density (i.e., carbon stock per unit area) and land cover greatly affect carbon sequestration. Previous studies have shown that land cover change detection strongly depends on spatia...
