Both of wrf_user_ll_to_xy in NCL and wrf.ll_to_xy in wrf-python return negative x values.

I'm trying to compare wrfout file with observations in some locations. I'm pretty sure that all the locations are in the wrf-domain. But when I use wrf_user_ll_to_xy in NCL and wrf.ll_to_xy in wrf-python to get the index of these locations, most of the x values I get are negative. I don't understand why. Is that caused by the projection? I used 'lat-lon' projection.

Can you upload your python/ncl scripts ?
Of course, Sir. These are my NCL and Python scripts. And I also attached my station's location file.
