class fips.problems.flux.FluxProblem(obs, prior, forward_operator, modeldata_mismatch, prior_error, constant=None, round_index=6)

Bases: InverseProblem

Atmospheric flux inversion problem.

Subclass of InverseProblem specialized for estimating spatial and temporal surface fluxes from observed atmospheric concentrations using a forward transport model. Supports multi-block state composition (e.g., fluxes + bias corrections).

Attributes

background	Background concentration.
concentration_error	Model-data mismatch covariance matrix for observations.
concentrations	Observed concentrations.
enhancement	The background-subtracted observation vector.
jacobian	Forward operator (Jacobian) mapping state to observations.
plot	Plotting interface for flux inversion results.
posterior_concentrations	Modelled concentrations from posterior fluxes.
posterior_flux_error	Posterior flux error covariance matrix after inversion.
posterior_fluxes	Posterior flux estimates after inversion.
prior_concentration_error	Covariance of the prior modelled concentrations from the prior flux error.
prior_concentrations	Modelled concentrations from prior fluxes.
prior_flux_error	Inventory error covariance matrix.
prior_fluxes	Prior flux inventory.
