    initial v1  
    11Specific questions I have about the FLEXPART-WRF output file include:
    22
    3 1. INFORMATION: SUBGRIDSCALE TERRAIN EFFECT IS NOT PARAMETERIZED DURING THIS SIMULATION. 
    4 I get this notice in my file and I don't know what it means.  It seems to say that only dispersion in the air is calculated.  Is that correct?

    1324Where does FLEXPART-WRF get this information from?  It seems like it comes from one of the WRF namelist files.  Does FLEXPART-WRF need the namelist files to work correctly or does FLEXPART-WRF get this information from the netCDF input data files?

    2843This error message makes it clear that I need to change the OUTGRID section of the input file.  I don't know how to change it.  WRF defines domain location using the latitude and longitude at the centre of the grid.  FLEXPART-WRF is looking for the Lower Left point and grid distance or upper right point.  I am trying to define a FLEXPART-WRF grid that starts at a lower left point of (-78.3169,45.5003), goes 147 km to the East and 121 km to the North.  Is this what I have defined in the flexwrf.input file?

    36 What is this trying to communicate?  It seems like it is trying to say that the specified grid size is greater than a grid size that FLEXPART-WRF has generated.  What input data or files does FLEXPART-WRF use to determine xr (FLX) and yr (FLX)?
