Table 2 Flux density time and space averages for the whole period 2005–2009

From: Assessing Lagrangian inverse modelling of urban anthropogenic CO₂ fluxes using in situ aircraft and ground-based measurements in the Tokyo area

	Prior flux	Posterior flux	Prior uncert	Posterior uncert
Rural	0.82	1.22	0.41	0.41
Urban	14.47	19.46	7.23	5.67
Sea	0.19	0.19	0.02	0.02
≥ 1 mg m⁻² s⁻¹	38.84	40.93	19.42	14.80
≥ 0.01 mg m⁻² s⁻¹	6.23	8.41	3.06	2.44
All grid	3.82	5.16	1.88	1.50

All values are in micro-mol CO₂ m⁻² s⁻¹ commonly adopted for CO₂ fluxes in the eddy covariance community (1 micro-mol CO₂ = 0.044 mg CO₂, the corresponding Additional file 6: Table S1 in mg CO₂ m⁻² s⁻¹ can be found). Space averages are taken in the area defined by the mask
