I have just installed a personal weather station and connected it online.Among other outputs, it has Relative and Absolute Barometric Pressure and I need advice on how to set these up.
These readings are adjustable and both read from the same barometer source. My weather station is 25 metres above sea level and there is a BOM weather station at sea level and less than a kl away. 25 metres needs a correction of 3mb.
If the BOM source read 1013mb, what should I set for relative and for absolute and what should I display as the barometer reading over the net?
Thank You
