the community earth system model ...
TopoSCALE v.1.0: downscaling gridded climate data in complex terrain
complex terrain climate data
2014/12/18
Simulation of land surface processes is problematic in heterogeneous terrain due to the the high resolution
required of model grids to capture strong lateral variability
caused by, for example, topo...
Downscaling a global climate model to simulate climate change over the US and the implication on regional and urban air quality
Downscaling a global climate model simulate climate change over the US regional and urban air quality
2014/12/12
Climate change can exacerbate future regional air pollution events by making conditions more favorable to form high levels of ozone. In this study, we use spectral nudging with the Weather Research an...
Downscaling the climate change for oceans around Australia
Global climate models climate change Marine Marine climate change the dynamic downscaling forecasting model
2014/12/10
At present, global climate models used to project changes in climate poorly resolve mesoscale ocean features such as boundary currents and eddies. These missing features may be important to realistica...

the downscaling bias correction regional climate simulations hydrological modeling
2014/12/9
The present study investigates a statistical approach for the downscaling of climate simulations focusing on those meteorological parameters most commonly required as input for climate change impact m...
Application of PLS-Regression as Downscaling Tool for Pichola Lake Basin in India
PLS Regression Precipitation VIP Score
2013/3/6
In this paper, downscaling models are developed using Partial Least Squares (PLS) Regression for obtaining projections of mean monthly precipitation to lake-basin scale in an arid region in India. The...
Precipitation downscaling using random cascades: a case study in Italy
Precipitat downscaling random cascades a case study
2010/9/10
We present a Stochastic Space Random Cascade (SSRC) approach to downscale precipitation from a Global Climate Model (hereon, GCMs) for an Italian Alpine watershed, the Oglio river (1440 km2). The SSRC...
Downscaling, parameterization, decomposition, compression: a perspective from the multiresolution analysis
Downscaling parameterization decomposition compression aperspective multiresolution analysis
2010/9/13
Geophysical models in general, and atmospheric models more specifically, are always limited in spatial resolutions. Due to this limitation, we face with two different needs. The first is a need for kn...
A meteo-hydrological forecasting chain: performance of the downscaling and rainfall-runoff steps in a small catchment
forecasting performance
2010/1/27
Forecasting ground effects of severe meteorological events with an adequate lead time is fundamental for civil protection scopes and is therefore an important challenge for the scientific community. T...
