- W1680212753 abstract "We study the fluctuations in the measured atmospheric CO2 records from several stations and show that it displays 1/f noise and multifractality. Using detrended fluctuation analysis and wavelet based methods, we estimate the scaling exponents at various time scales. We also simulate CO2 time series from an atmospheric chemistry-transport model (CTM) and show that eventhough the model results are in broad agreement with the measured exponents there are still some discrepancies between them. The implications for sources and sinks inversion of atmospheric-CO2 is discussed. PACS numbers: 91.10.Vr,89.75.Fb,92.70.Np,05.45.Df Atmospheric carbon dioxide is thought to be one of the greenhouse gases primarily responsible for the current phase of global warming [1]. In view of this significance for the global climate and life on earth, considerable effort has gone into measuring CO2 from various platforms in the last several decades. Direct record of atmospheric CO2 is available since the 1950s and hourly time series are constructed more recently at several measurement stations [2, 3]. In the context of atmospheric systems, where the mean behaviour is reasonably well known from such long term records, the fluctuations decide the actual outcome. However, the fluctuation properties of CO2 time series have not been studied in sufficient detail. Such a study would help identify the class of process, e.g, correlated random walk, Levy flight etc., underlying the CO2 biogeochemistry and will provide a clue if it is a selforganised critical system. Secondly, this would serve as a diagnostic tool to compare the outputs from ab initio atmospheric CTMs as well as to constrain the processes that could be represented in them. This could lead to better understanding of the global CO2 cycle. Scale invariance and 1/f noise are considered to be the signatures of complex systems [4]. In recent years, several time series from physiological, economic, physical systems including those of atmospheric parameters have been subjected to scaling and spectral analysis [5]. If x(t) be the given time series, then the scaling can be expressed as, x(�t) ≈ � H x(t), where the symbol ≈ de" @default.
