- Retrieval of atmospheric CO2 with enhanced accuracy and precision from SCIAMACHY: validation with FTS measurements and comparison with model results (2011, background): “[2007] and Chevallier et al. [2007] found that undetected biases of a few tenths of a part per million on regional scales can limit surface flux inverse modeling.”
- Balancing aggregation and smoothing errors in inverse models (2015, background): “…error statistics Several approaches have been presented to obtain approximate error characterization (e.g., Courtier et al., 1994; Desroziers et al., 2005; Chevallier et al., 2007; Bousserez et al., 2015), but they can be computationally expensive An excessively large state vector relative to the…”
- Estimating surface CO 2 fluxes from space-borne CO 2 dry air mole fraction observations using an ensemble Kalman Filter (2008, methodology): “Previous work has implemented coherent bias by relating it with to the sub-micron aerosols (Chevallier et al., 2007a).”
- Carbon monitoring system flux estimation and attribution: impact of ACOS-GOSAT XCO2 sampling on the inference of terrestrial biospheric sources and sinks (2014, methodology): “In this study, the posterior flux uncertainty is approximated using a Monte Carlo approach (Chevallier et al., 2007).”
- Impact of correlated observation errors on inverted CO2 surface fluxes from OCO measurements (2007, background): “…of the off-diagonal terms in R is given by the value of the cost function J (equation 1) at its minimum: as expected for an optimal system [e.g., Chevallier et al., 2007], it is very close to the number of observations (243,500) and the reduced chi-squared (J divided by the number of…”
- Improved retrievals of carbon dioxide from Orbiting Carbon Observatory-2 with the version 8 ACOS algorithm (2018, background): “Such measurements are critical for inferring sources and sinks of carbon, and how these sources and sinks change over time due to both anthropogenic and natural causes (e.g., Rayner and O’Brien, 2001; Chevallier et al., 2007; Baker et al., 2010).”
