Thanks again.
Yes, I was aware of Akureyri, but there is a big difference in results.
I contacted the Icelandic Meteorological Service and they told me to use N (north) and W (west) for the coordinations of this particular station.
Example: 65°35.107’N, 17°46.000’W
or add a “-” in front of the last coordinates: 65.5851, -17.7667
If that doesn’t work, I do thank you for your time and effort.
