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.

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.
