Setting the mapper with output concentrations

2. Setting the mapper with output concentrations#

Here, we propose to extract output concentrations from pre-computed output files. This is possible in the template by using the option only_outputs in the model paragraph.

Compared to the previous yaml, the following elements have been added:

  1. mode paragraph: this is the execution mode. It is needed for pyCIF to go further than the initialization step. Here we are computing a forward simulation to compare simulations with observations

  2. chemistry paragraph: this paragraph indicates information about species to be transported and/or emitted in the model

  3. datavect paragraph: this paragraph indicated all required information about pyCIF inputs. Further details is given here

In the example above, observations are generated at random locations. If one needs/wants to use a file of its own making, please refer to the dedicated documentation page about observation inputs (here) to properly prepare the file.

Once successfully running, the forward working files are saved in the folder $runsubdir/obsoperator/fwd_0000/. In particular, the output simulations and corresponding observations are saved here: $runsubdir/obsoperator/fwd_0000/obsvect.
