Comparison between a forward simulation and satellite data

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

For satellite data, the plugin satellites has been designed for conveniency and includes various transformations. It is then easy to specify the monitor formatted files to use with the minimum information on how to transform the model’s output into equivalents of the data, e.g. total or partial columns. The names of the parameters must be the same as the names in the output of the model i.e. the names of the species in OUPUT_SPECIES. The format of the file name provided makes it possible to divide a large amount of data into smaller monitor.nc files, e.g. per month or even per smaller chunks for satellite data.
