Just remind:
* '''If you plan to do a Weather station''' then you have to care about the correction in order calculate the normalized value at sea level. Altitude is not useful since the weather station doesn't move.
* '''If you plan to do a Weather station''' then you will have to calculate the normalized pressure value at sea level. You have to know the height of the sensor (the weather station doesn't move).
* '''if you need a flying sensor''' in a rocket then you have to care about the baseline value (sea level pressure {{underline|of the day}}) for have a accurate measure the the altitude.
