Atmospheric Pressure and Density

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>

Available units: hPa, Pa, psi

Examples

• Display the predicted evolution of the adjusted pressure for the next three days. https://api.meteomatics.com/__replace__0T00:00:00ZP3D:PT6H/msl_pressure:hPa/47.412164,9.340652/html

  

Surface Pressure

Gives the surface pressure.

sfc_pressure:<unit>

Available units: hPa, Pa, psi

Examples
