wrong grid for LM external parameters – in #10: INT2LM

in #10: INT2LM

<p> Dear all, <br/> I am trying to run Int2lm over north Italy at resolution of about 1km (0.009°). I have generated an external parameter file covering a quite larger domain, but I obtain the following error message: </p> <p> <pre> <span class="caps">OPEN</span>: ncdf-file: /u1/bued185/RUN_URBAN/int2lm/const/domain2016050611155.nc external data file namelist input ie_ext 450 450 je_ext 450 450 lonll -1.45000004768372 -1.08000000000000 latll -2.00000000000000 -1.19000000000000 lonur 2.59100008010864 1.88100000000000 latur 2.04099988937378 1.68100000000000 dlon 9.000000284615497E-003 8.999999999999999E-003 dlat 8.999999753616435E-003 8.999999999999999E-003 pollat 45.0000000000000 45.0000000000000 pollon -172.000000000000 -172.000000000000 polgam 0.000000000000000E+000 0.000000000000000E+000 wrong grid for LM external parameters <strong>——————————————————————————————</strong> * <span class="caps">PROGRAM</span> <span class="caps">TERMINATED</span> <span class="caps">BECAUSE</span> OF <span class="caps">ERRORS</span> DETECTED * IN <span class="caps">ROUTINE</span>: int2lm_org * * <span class="caps">ERROR</span> <span class="caps">CODE</span> is 2 * Error in read_nc_gdefs_ext_lm</pre> </p> <p> <br/> The namelist <span class="caps"> LMGRID </span> I am using is the following: </p> <p> <pre> &amp;LMGRID ielm_tot=330, jelm_tot=320, kelm_tot=40, pollat = 45.0, pollon = -172.0, dlon=0.009, dlat=0.009, irefatm=2, delta_t=100, h_scal=10000, startlat_tot = -1.19, startlon_tot = -1.08,</pre> </p> <p> <br/> Could you please help me ? </p>

The namelist LMGRID I am using is the following: 

 &LMGRID
  ielm_tot=330, jelm_tot=320, kelm_tot=40,
  pollat =  45.0, pollon = -172.0,
  dlon=0.009, dlat=0.009,
  irefatm=2,
  delta_t=100, h_scal=10000,
  startlat_tot  = -1.19, startlon_tot  = -1.08,


Could you please help me ?

<p> Although the external data can cover a larger area the grid mesh in the overlapping region has to be exactly the same as defined in the namelist. In your case the definition <code> startlon_tot = -1.08 </code> seems to be the problem, please try e.g. <code> startlon_tot = -1.081 </code> <code> startlon_tot = -1.09 </code> </p>
