On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites:atmospheres – radiative transfer
2011/8/16
Abstract: Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clou...
A semi-analytical solution for the mean wind profile in the Atmospheric Boundary Layer:the convective case
semi-analytical solution mean wind profile Atmospheric Boundary Layer convective case
2010/3/5
A novel methodology to derive the average wind profile from the Navier-Stokes equations is presented. The development employs the Generalized Integral Transform Technique (GITT), which combines series...
Est modus in rebus: analytical properties of multi-model ensembles
Est modus rebus analytical properties multi-model ensembles
2009/12/31
In this paper we investigate some basic properties of the multi-model ensemble systems, which can be deduced from a general characteristic of statistical distributions of the ensemble members with the...
A quasi-analytical ice-sheet model for climate studies
quasi-analytical ice-sheet model climate studies
2009/11/12
A simple quasi-analytical model is developed to study the response of ice-sheets to climate change. The model is axisymmetrical and rests on a bed with a constant slope. The mechanics are highly param...
Analytical treatment of ice sublimation and test of sublimation parameterisations in two–moment ice microphysics models
Analytical treatment ice sublimation two–moment ice microphysics models
2009/10/9
We derive an analytic solution to the spectral growth/sublimation equation for ice crystals and apply it to idealised cases. The results are used to test parameterisations of the ice sublimation proce...
Comment on "Comparisons with analytical solutions from Khvorostyanov and Curry (2007) on the critical droplet radii and supersaturations of CCN with insoluble fractions" by Kokkola et al. (2008)
analytical solutions Khvorostyanov critical droplet radii CCN
2009/8/25
Analytical solutions for the critical radii and supersaturations of the cloud condensation nuclei (CCN) with insoluble fractions were derived by Khvorostyanov and Curry (2007, hereafter KC07). These s...
Comparison of analytical methods for Humic Like Substances (HULIS) measurements in atmospheric particles
Humic Like Substances HULIS atmospheric particles
2009/8/25
Humic-Like Substances (HULIS) are a major contributor to the organic carbon in atmospheric aerosol. It would be necessary to standardize an analytical method that could be easily and routinely used fo...
An analytical inversion method for determining regional and global emissions of greenhouse gases: Sensitivity studies and application to halocarbons
analytical inversion method determining regional and global emissions greenhouse gases halocarbons
2009/3/13
A new analytical inversion method has been developed to determine the regional and global emissions of long-lived atmospheric trace gases. It exploits in situ measurement data from three global networ...
Characterization of carbonaceous aerosols during the MINOS campaign in Crete, July–August 2001: a multi-analytical approach
carbonaceous aerosols MINOS multi-analytical approach
2009/3/11
During the major part of the Mediterranean Intensive Oxidant Study (MINOS) campaign (summer 2001, Crete Isl.), the Marine Boundary Layer (MBL) air was influenced by long range transport of biomass bur...
Technical note: analytical estimation of the optimal parameters for the EOF retrievals of the IASI Level 2 Product Processing Facility and its application using AIRS and ECMWF data
EOF retrievals IASI Level 2 Product Processing Facility ECMWF
2009/1/4
The Empirical Orthogonal Function (EOF) retrieval technique consists of calculating the eigenvectors of the spectra to later perform a linear regression between these and the atmospheric states, this ...
Source apportionment of submicron organic aerosols at an urban site by factor analytical modelling of aerosol mass spectra
submicron organic aerosols aerosol mass spectra
2008/12/4
Submicron ambient aerosol was characterized in summer 2005 at an urban background site in Zurich, Switzerland, during a three-week measurement campaign. Highly time-resolved samples of non-refractory ...
A semi-analytical method for calculating rates of new sulfate aerosol formation from the gas phase
semi-analytical method sulfate aerosol gas phase
2008/11/12
The formation of new aerosol from the gas phase is commonly represented in atmospheric modeling with parameterizations of the steady state nucleation rate. Present parameterizations are based on class...
