This table shows the atmospheric pressure at a given altitude over the sea level.
The data was generated from the model internally used by DekoPro 1.0 in the implementation of altitude diving. Of course, this model doesn't reflects the variations origined by weather conditions.
In any case this data can be used like as an altimeter, so you can't get the altitude from the atmospheric pressure read on a barometer (specially at altitudes greater than 15000 feet). The intended functionality is only for altitude diving corrections.
