2011/2/25
A detailed full-chemistry 3-D chemistry and transport model (CTM) is used to evaluate the current stratospheric O3 parameterisation in the European Centre for Medium-Range Weather Forecasts (ECMWF) mo...
A linear CO chemistry parameterization in a chemistry-transport model: evaluation and application to data assimilation
A linear CO chemistry parameterization a chemistry-transport model data assimilation
2010/8/16
This paper presents an evaluation of a new linear parameterization valid for the troposphere and the stratosphere, based on a first order approximation of the carbon monoxide (CO) continuity equation....

Linear and nonlinear post-processing numerically forecasted surface temperature
2009/11/12
In this paper we test different approaches to the statistical post-processing of gridded numerical surface air temperatures (provided by the European Centre for Medium-Range Weather Forecasts) onto th...
Prediction of minimum temperatures in an alpine region by linear and non-linear post-processing of meteorological models
minimum temperatures alpine region linear and non-linear post-processing meteorological models
2009/11/3
Model Output Statistics (MOS) refers to a method of post-processing the direct outputs of numerical weather prediction (NWP) models in order to reduce the biases introduced by a coarse horizontal reso...
Rebuilding sources of linear tracers after atmospheric concentration measurements
linear tracers atmospheric concentration measurements
2009/3/11
The identification of widespread sources of passive tracers out of atmospheric concentration measurements has become an important challenge of modern meteorology. The paper proposes some mathematical ...
A practical demonstration on AMSU retrieval precision for upper tropospheric humidity by a non-linear multi-channel regression method
AMSU retrieval precision upper tropospheric humidity non-linear multi-channel regression method
2009/2/6
A neural network algorithm inverting selected channels from the Advance Microwave Sounding Unit instruments AMSU-A and AMSU-B was applied to retrieve layer averaged relative humidity. The neural netwo...
Emergence of a tracer source from air concentration measurements, a new strategy for linear assimilation
air concentration measurements linear assimilation
2009/1/23
The measurement of atmospheric concentrations by a monitoring network is a promising tool for the identification of the widespread sources of trace species. The paper addresses the case of the species...
Cluster activation theory as an explanation of the linear dependence between formation rate of 3nm particles and sulphuric acid concentration
Cluster activation theory linear dependence formation rate of 3nm particles sulphuric acid concentration
2009/1/4
According to atmospheric observations new particle formation seems to be a function of sulphuric acid concentration to the power from one to two. The nucleation theorem then predicts that the critical...

linear ozone photochemistry parametrizations stratosphere-troposphere system
2008/12/1
This paper evaluates the performance of various linear ozone photochemistry parametrizations using the stratosphere-troposphere data assimilation system of the Met Office. A set of experiments were ru...
Technical Note: Review of methods for linear least-squares fitting of data and application to atmospheric chemistry problems
linear least-squares atmospheric chemistry
2008/11/19
The representation of data, whether geophysical observations, numerical model output or laboratory results, by a best fit straight line is a routine practice in the geosciences and other fields. While...
Non-linear statistical downscaling of present and LGM precipitation and temperatures over Europe
Non-linear statistical LGM Europe
2008/11/7
Local-scale climate information is increasingly needed for the study of past, present and future climate changes. In this study we develop a non-linear statistical downscaling method to generate local...
