Comparison between a forward simulation and satellite data

If you are not using ready-made monitor.nc files specified in obsvect, the simplest option is to use the datavect components dedicated to observations.

For satellite data, the satellites plugin was designed for convenience and bundles various transformations. You can specify the monitor files with minimal information on how to transform the model output into observation equivalents (e.g. total or partial columns). The parameters names must match the species names in OUTPUT_SPECIES. Using a date pattern in the filename allows splitting large datasets into smaller monitor.nc files, e.g. per month or per shorter chunk.
