How to output PM25 concentrations #48

Closed JessMBemep closed 5 years ago

JessMBemep commented 5 years ago

Hi, I am trying to output all variables related to PM25 variables: SURF_ug_PM25 SURF_ug_PM25_rh50 SURF_ug_PM25X SURF_ug_PM25X_rh50 It seems that they have not included by default, I modified the config_emep.nml by addind the corresponding lines in the OutConcs namelist. The model is running well but I verified the output Base_day.nc and it is not outputing the desired variables.

JessMBemep commented 5 years ago

... neither in the variables 2d of Base_month.nc are these variables included. Might I modify other thing than the OutConcs namelist?

avaldebe commented 5 years ago

The following lines on the OutputConcs namelist will produce daily and (hourly) instantaneous output

  'PMFINE'         ,'ug','2d' ,'AIR_CONCS','GROUP','',! no output, needed by SURF*PM25*
  'PM10'           ,'ug','2d' ,'AIR_CONCS','GROUP','',! no output, needed by SURF*PM10*
  'SURF_PM25water' ,'ug','2d' ,'PM25water','MISC' ,'',! no output, needed by SURF*PM*rh50
  'SURF_ug_PM25'        ,'ug' ,'2d','PM25'      ,'MISC','DI',
  'SURF_ug_PM25X'       ,'ug' ,'2d','PM25X'     ,'MISC','DI',
  'SURF_ug_PM25X_rh50'  ,'ug' ,'2d','PM25X_rh50','MISC','DI',
  'SURF_ug_PM25_rh50'   ,'ug' ,'2d','PM25_rh50' ,'MISC','DI',
  'SURF_ug_PM10_rh50'   ,'ug' ,'2d','PM10_rh50' ,'MISC','DI',

Do I eliminate the lines:

  'PMFINE'              ,'ug'  ,'2d','AIR_CONCS','GROUP','YMD',
  'PM10'                ,'ug'  ,'2d','AIR_CONCS','GROUP','YMD',

to include 

  'PMFINE'         ,'ug','2d' ,'AIR_CONCS','GROUP','',! no output, needed by SURF*PM25*
  'PM10'           ,'ug','2d' ,'AIR_CONCS','GROUP','',! no output, needed by SURF*PM10*

That was a question

JessMBemep commented 5 years ago

I also need these variables in the Base_fullrun.nc output. How to set it on the OutputConcs namelist?

It depends if you actually want SURF_ug_PMFINE and SURF_ug_PM10 output, or you only want other kinds of PM outputs, such as SURF_ug_PM25_rh50 and SURF_ug_PM10_rh50.

The last string on each line describes the types of output:

An empty string will force the model to create the internal buffers and perform the calculations, but no output will be written out.

can this model be used outside Europe

gitpeterwind commented 5 years ago

Yes, the model can be used for any region. It has been applied for global modelling, and also regional studies in Asia, and a project for South America is underway too. Here is a concrete example of regional application in India: https://www.atmos-chem-phys.net/18/103/2018/

fipoucat commented 5 years ago

That' great, I am from Wes Africa and wish to test for air quality simulations using wrf as atmosphere.

Certainly people on the list have experience on this and could help.

Kind regards
