| 摘要 |
The invention relates to a specific selection of the observations applied to a model consisting of a direct model and a reverse model, in order to deduce gas production and absorption flows, such as greenhouse gases in a geographical area, by measuring the concentrations thereof at stations (3) and by simulating the movements thereof from production or absorption locations (1, 2). Said selection consists of estimating the concentrations by using the two models, establishing the difference between these estimates and comparing same to thresholds, which advantageously depend on errors or uncertainties estimated in the models. |
