Dear Flexpart community,

I have encountered an error message when using ERA5 data (downloaded by flex_extract v7.1.2) as the model input for Flexpart:

 ECMWF metdata detected
ECCODES ERROR   :   wrong size (244) for pv it contains 276 values 
ECCODES ERROR   :  gridcheck: Error Passed array is too small

It seems to point out the wrong size of the pv data (potential vorticity?).

But the FLEXPART model can run without bugs if I use ERA-interim data. So I guess the error may come from the ERA5 data.

Below is my CONTROL file to download the ERA5 data using flex_extract v7.1.2:

Is there anything wrong with the CONTROL setting? Any helps/hints with this error message would be much appreciated. Thanks a lot!

Hello,

I am using v10.4 with GFS data. I am receiving the following error:

FLEXPART error: Too many grid points in x direction. Reduce resolution of wind fields. Or change parameter settings in file par_mod.

721 361

I have changed these values in par_mod. I have also checked with grep that these values do not appear in the file anymore. Yet, I continue to receive the same error message as above.

Could someone tell me what I'm doing wrong?

Thanks.

Hello,

I am trying to understand the initialization of particles in init_domainfill.f90. I'm having trouble understanding the following lines (54 to 57) :

  nx_we(1)=max(int(xpoint1(1)),0)
  nx_we(2)=min((int(xpoint2(1))+1),nxmin1)
  ny_sn(1)=max(int(ypoint1(1)),0)
  ny_sn(2)=min((int(ypoint2(1))+1),nymin1)

As far as I understand nx_we, ny_sn are the grid indices for western, eastern, southern and northern boundary of the release domain.

My question is the following : what happens if one of the longitudes and/or latitudes bounding the domain are negative? That is if one of xpoint1, xpoint2, ypoint1, ypoint2 < 0 ? It seems to me that these code lines restrict our domain to positive values. However, I know from experience, when using Flexpart, that there is no such restriction.

Thank you in advance!
