AN ANALYTIC PARAMETERIZATION OF SELF-GRAVITY WAKES IN SATURN’S RINGS, WITH APPLICATION TO OCCULTATIONS AND PROPELLERS
planets and satellites individual (Saturn)–planets and satellites rings
2015/12/25
We have developed a semianalytic method of parameterizing N-body simulations of self-gravity wakes in Saturn’s rings, describing their photometric properties by means of only six numbers: three optica...
Affine Controller Parameterization for Decentralized Control over Banach Spaces
Banach Spaces Decentralized Control
2015/6/19
We cast the problem of optimal decentralized control as one of minimizing a closed-loop norm subject to a subspace constraint on the controller. In this note we consider continuous linear operators on...
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...
Development of a new semi-empirical parameterization for below-cloud scavenging of size-resolved aerosol particles by both rain and snow

2014/12/18
t. A parameter called the scavenging coefficient 3
is widely used in aerosol chemical transport models (CTMs)
to describe below-cloud scavenging of aerosol particles by
rain and snow. However...
An improved parameterization of tidal mixing for ocean models
ocean models improved parameterization
2014/12/18
Two modifications to an existing scheme of tidal
mixing are implemented in the coarse resolution ocean component of a global climate model. First, the vertical distribution of energy flux...
Development of a parameterization of black carbon aging for use in general circulation models
parameterization of black carbon aging general circulation models
2014/12/16
A parameterization of black carbon (BC) aging in the atmosphere is developed for use in general circulation models (GCMs) that separately treat hydrophobic BC and hydrophilic BC modes but do not expli...
Evaluating a lightning parameterization based on cloud-top height for mesoscale numerical model simulations
lightning parameterization cloud-top height mesoscale numerical model simulations
2014/12/16
The Price and Rind lightning parameterization based on cloud-top height is a commonly used method for predicting flash rate in global chemistry models. As mesoscale simulations begin to implement flas...
EMPOL 1.0: a new parameterization of pollen emission in numerical weather prediction models
pollen emission numerical weather prediction
2014/12/12
Simulating pollen concentrations with numerical
weather prediction (NWP) systems requires a parameterization for pollen emission.
A subgrid parameterization scheme for precipitation

This paper describes the coupling of the Community Atmosphere Model (CAM) version 5 with a unified multi-variate probability density function (PDF) parameterization, Cloud Layers Unified by Binormals ...
Mass-flux subgrid-scale parameterization in analogy with multi-component flows: a formulation towards scale independence
Mass-flux subgrid-scale multicomponent flows a formulation towards scale independence
2014/12/10
A generalized mass-flux formulation is presented, which no longer takes a limit of vanishing fractional areas for subgrid-scale components. The presented formulation is applicable to a~situation in wh...
