Atmospheric Pressure and Density API Parameters

The computation of pressure parameters is based on data of NASA's SRTM digital elevation model, where it is available (between 60°N and 60°S). Model topography is used elsewhere.

Pressure Adjusted to Sea Level

Gives the pressure adjusted to sea level.

msl_pressure:<unit>
