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...
A simple parameterization of the short-wave aerosol optical properties for surface direct and diffuse irradiances assessment in a numerical weather model
he short-wave aerosol optical properties surface direct
2014/12/18
Broadband short-wave (SW) surface direct and
diffuse irradiances are not typically within the set of output
variables produced by numerical weather prediction (NWP)
models. However, they are freque...

Sensitivity of precipitation forecasts convective parameterization in the October 2007 Flash Flood Valencia Region
2010/9/10
The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is an area prone to torrential rains, especially the north of Alicante province and the south of Valencia province. In October...
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...
