The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier transform spectrometers (FTSs) that record near-infrared (NIR) spectra of the sun. From these spectra, accurate and precise observations of CO2 column-averaged dry-air mole fractions (denoted XCO2) are retrieved. TCCON FTS observations have previously been used to validate satellite estimations of XCO2; however, our knowledge of the short-term spatial and temporal variations in XCO2 surrounding the TCCON sites is limited. In this work, we use the National Institute for Environmental Studies (NIES) Eulerian three-dimensional transport model and the FLEXPART (FLEXible PARTicle dispersion model) Lagrangian particle dispersion model (LPDM) …

This paper presents a novel retrieval algorithm for the rapid retrieval of the carbon dioxide total column amounts from high resolution spectra in the short wave infrared (SWIR) range observations by the Greenhouse gases Observing Satellite (GOSAT). The algorithm performs EOF (Empirical Orthogonal Function)-based decomposition of the measured spectral radiance and derives the relationship of limited number of the decomposition coefficients in terms of the principal components with target gas amount and a priori data such as airmass, surface pressure, etc. The regression formulae for retrieving target gas amounts are derived using training sets of collocated GOSAT and ground-based observations. …

TCCON (Total Carbon Column Observing Network) is dedicated to the precise measurements of greenhouse gases such as CO2 and CH4. TCCON measurements are used extensively for satellite validation, for atmospheric chemistry modeling, and for carbon cycle studies. With the global effort to cap greenhouse gas emissions, TCCON has taken on a vital role in validating past, current, and future satellite missions such as Japan's Greenhouse Gases Observing Satellite (GOSAT & GOSAT-2), National Aeronautics and Space Administration's (NASA) Orbiting Carbon Observatory-2 (OCO-2 & future OCO-3), and others. However, the lack of reliable validation data for satellite-based greenhouse gas observations in the …
