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>
Available units: hPa, Pa, psi
Examples
- Display the predicted evolution of the adjusted pressure for the next three days over Berlin. https://api.meteomatics.com/2023-03-20T00:00:00Z--2023-03-23T00:00:00Z:PT6H/msl_pressure:hPa/47.412164,9.340652/html
Mean Pressure Adjusted to Sea Level over the Last 10 Years
Gives the mean adjusted pressure over the last 10 years on a certain date at a specific location.
msl_pressure_10y_mean:<unit>
Available units: hPa, psi
Examples:
- Compare the mean adjusted pressure of the last ten years with the adjusted pressure of 2022.
