Hi - Clarification please on the effect of terrain height versus 'forecast' height. I would like to know with the forecast setting at 'surface' - is this ground surface regardless of terrain height or do I need to set the terrain height in the forecast height to get the correct reading?

I hope this makes sense.

Thank you
Regards
