The critical role of trace gases in global atmospheric change makes an improved
understanding of these gases imperative. Measurements of the distributions of these gases …

This paper deals with the estimation of the noise covariance matrices of systems described
by state‐space models. Stress is laid on the systematic survey and classification of both the …

The meaning of 'baseline'as applied to measurements of CN, at atmospheric monitoring
sites such as Cape Grim, is discussed and the idea that a 'baseline'exists only in a statistical …

The Kalman filter is applied to the analysis of trace gas concentrations in ice core air
bubbles. A simple model for atmospheric methane is investigated to infer information about …

In recent years there has been an increasing appreciation of the degree of natural temporal
variability in the global carbon cycle. Techniques that can estimate the variability and …

A detailed analysis of the time series of the monthly average atmospheric CO2
concentrations from March 1958 to December 1985 has been carried out. Seasonal …

Techniques for calculating the future atmospheric CO2 concentrations to be expected from
various possible patterns of future CO2 release are reviewed. Particular attention is given to …

Uncertainties in the interpretations of CO2 data arise from errors in the observations and
model relations. The space–time variations of CO2 on the global scale are analysed in terms …

A number of shortcomings associated with the use of smoothing and least squares splines
for data analysis in general, and also in some specific past CO2 analyses are considered. A …

This document lists references relevant to inversions of CO2, the estimation of the net
surface flux of CO2 given observations of concentrations. It includes all references from my …
