A Bayesian method for the analysis of deterministic and stochastic time series
methods:statistical brown dwarf
2012/11/23
I introduce a general, Bayesian method for modelling univariate time series data assumed to be drawn from a continuous, stochastic process. The method accommodates arbitrary temporal sampling, and tak...
Isoline retrieval: An optimal sounding method for validation of advected contours
Isoline retrieval: An optimal sounding method for validation of advected contours
2012/2/28
The study of chaotic mixing is important for its potential to improve our understanding of fluid systems. Contour advection simulations provide a good model of the phenomenon by tracking the evolution...
Novel method of generation of Ca(HCO3)2 and CaCO3 aerosols and first determination of hygroscopic and cloud condensation nuclei activation properties
Ca(HCO3)2 and CaCO3 aerosols hygroscopic and cloud condensation nuclei activation properties
2010/9/21
Atmospheric mineral aerosols contain CaCO3 as a reactive component. A novel method to produce CaCO3 aerosol was developed by spraying Ca(HCO3)2 solution, which was generated from a CaCO3 suspension an...
A new method for deriving aerosol solar radiative forcing and its first application within MILAGRO/INTEX-B
aerosol solar radiative forcing first application MILAGRO/INTEX-B
2010/8/25
We introduce a method for deriving aerosol spectral radiative forcing along with single scattering albedo, asymmetry parameter, and surface albedo from airborne vertical profile measurements of shortw...
Stochastic fields method for sub-grid scale emission heterogeneity in mesoscale atmospheric dispersion models
Stochastic fields method sub-grid scale emission heterogeneity mesoscale atmospheric dispersion models
2010/1/18
The stochastic fields method for turbulent reacting flows has been applied to the issue of sub-grid scale emission heterogeneity in a mesoscale model. This method is a solution technique for the proba...
Technical note: a new method for the Lagrangian tracking of pollution plumes from source to receptor using gridded model output
Lagrangian tracking pollution plumes gridded model output
2009/5/7
Lagrangian particle dispersion models (LPDMs) are powerful and popular tools used for the analysis of atmospheric trace gas measurements. However, it can be difficult to determine the transport pathwa...
Technical Note: Novel method for water vapour monitoring using wireless communication networks measurements
Novel method water vapour monitoring wireless communication networks measurements
2009/5/7
Weather conditions and atmospheric phenomena affect the electromagnetic channel, causing attenuations to the radio signals. Thus, wireless communication networks are in effect built-in environmental m...
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...
Assessing positive matrix factorization model fit: a new method to estimate uncertainty and bias in factor contributions at the measurement time scale
Assessing positive matrix factorization model factor contributions measurement time scale
2009/3/12
A Positive Matrix Factorization receptor model for aerosol pollution source apportionment was fit to a synthetic dataset simulating one year of daily measurements of ambient PM2.5 concentrations, comp...

2009/3/12
This paper presents experiments of PM10 data assimilation with the optimal interpolation method. The observations are provided by BDQA (Base de Données sur la Qualité de l'Air), whose monitoring netwo...
The EISCAT meteor-head method – a review and recent observations
EISCAT meteor-head method Barker codes dual-frequency target sizes
2009/2/25
Since the very first meteor observations at EISCAT in December 1990, the experimental method has improved significantly. This is due to a better understanding of the phenomenon and a recent major upgr...
