Evaluation of Land Development Impact on a tropical Watershed Hydrology Using Remote Sensing and GIS
Water Resources GIS Remote Sensing
2015/1/5
Understanding how the land use change influence the river basin hydrology will enable planners to formulate policies to minimize the undesirable effects of future land use changes. Land cover changes ...
Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Erosion-Deposition Model Space Borne Multispectral Data
2015/1/4
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
Candidates for multiple impact craters?: Popigai and Chicxulub as seen by the global high resolution gravitational field model EGM2008
Candidates for multiple impact craters Popigai and Chicxulub global high resolution gravitational field model EGM2008
2014/12/31
In 2008 the new Earth Gravitational Model (EGM2008) was released. It contains a complete set of spherical harmonic coefficients of the Earth's gravitational potential (Stokes parameters) to degree 219...
Pre-heating by pre-virialization and its impact on galaxy formation
dark matter large-scale structure of the universe
2014/12/24
We use recent observations of the H i mass function to constrain galaxy formation. The data conflict with the standard model where most of the gas in a low-mass dark matter halo is assumed to settle i...
Submillimeter Wave Astronomy Satellite observations of Comet 9P/Tempel 1 and Deep Impact
Comet Tempel-1 Radiative Transfer Radio Observations Comets
2014/12/23
On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the com...
USING 21 cm ABSORPTION IN SMALL IMPACT PARAMETER GALAXY-QUASAR PAIRS TO PROBE LOW-REDSHIFT DAMPED AND SUB-DAMPED Ly alpha SYSTEMS
low-redshift damped Lyα (DLA) sub-DLA quasar absorbers
2014/12/20
To search for low-redshift damped Lyα (DLA) and sub-DLA quasar absorbers, we have conducted a 21 cm absorption survey of radio-loud quasars at small impact parameters to foreground galaxies selected f...
The impact of aerosol optical depth assimilation on aerosol forecasts and radiative effects during a wild fire event over the United States
aerosol forecasts radiative effects
2014/12/19
The Gridpoint Statistical Interpolation three-dimensional variational data assimilation (DA) system coupled with the Weather Research and Forecasting/Chemistry (WRF/Chem) model was utilized to improve...
Freeze/thaw processes in complex permafrost landscapes of northern Siberia simulated using the TEM ecosystem model: impact of thermokarst ponds and lakes
Freeze/thaw processes complex permafrost landscapes northern Siberia simulated TEM ecosystem model thermokarst ponds and lakes
2014/12/19
Freeze/thaw (F/T) processes can be quite different under the various land surface types found in the complex tundra of the Arctic, such as polygonal tundra (wet center and dry rims), ponds, and thermo...
A scale-dependent blending scheme for WRFDA: impact on regional weather forecasting
A scale-dependent blending scheme WRFDA regional weather forecasting
2014/12/19
Due to limitation of the domain size and limited observations used in regional data assimilation and forecasting systems, regional forecasts suffer a general deficiency in effectively representing lar...
Aircraft routing with minimal climate impact: the REACT4C climate cost function modelling approach (V1.0)
minimal climate impact function modelling approach
2014/12/18
In addition to CO2, the climate impact of aviation is strongly influenced by non-CO2 emissions, such as
nitrogen oxides, influencing ozone and methane, and water
vapour, which can lead t...
