Description

The problem with NOx
there is no emission_nox_apply, so the vertical distribution of emissions is done in 'declare' at the beginning of the run, and is used until a new month is started.
There are few issues with that approach:
  • you cannot test if cutting a run into chunks give the same results as not cutting it. Note: this is strictly an issue with runs shorter than a month. This can be temporary overcome by switching off NOx emissions (comment the corresponding line in chemistry.F90 around line 1052).
  • it does not correctly account for the geopotential height (gph of beginning of the month is used for every time step)
  • if we want to add a daily/weekly cycle later on

We probably need to add an emission_nox_apply and call it in chemie, and not in emission_apply as it is done for other species.
