Precision requirements for space-based image data



[1] Precision requirements are determined for space-based column-averaged CO2 dry air mole fraction image data. These requirements result from an assessment of spatial and temporal gradients in image the relationship between image precision and surface CO2 flux uncertainties inferred from inversions of the image data, and the effects of image biases on the fidelity of CO2 flux inversions. Observational system simulation experiments and synthesis inversion modeling demonstrate that the Orbiting Carbon Observatory mission design and sampling strategy provide the means to achieve these image data precision requirements.
