I was going to point this out too, that just adding a fixed offset in hPa is not the same as applying the altitude formula. So, from a hard-core viewpoint, perhaps the best approach is: map absolute pressure to station pressure ignore "relative pressure" as unsound let StdCalculate computer altimiter pressure and barometer pressure with an implicit let the user calibrate the GW1000's absolute pressure, or enter in a calibtration in StdCalibrate (or just not worry about it) -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
