PWS API v2 - Pressure Question
-
I'm assuming you want Sea Level Pressure sent via the API and not Station Pressure or something else. Can someone confirm?
-
@mcrossley Hello, stations provide Pressure in the altitude, where stations are located.
-
@Suty Sorry, that is still not clear to me. I think you mean station pressure, but there are three commonly used pressure values in meteorology...
Station Pressure (sometimes called Absolute Pressure) - the raw pressure value read by the sensor with no reduction applied.
or
Sea Level Pressure (QNH) - Station pressure reduced to sea level using temperature and humidity.
or
Altimeter - Station pressure reduced to sea level using a temperature profile of the "standard" atmosphere. -
@mcrossley Hello, you are right, but answer was not clear at all. Weather stations primarily report Mean Sea Level (MSL) Pressure, which is the station's atmospheric pressure corrected to sea level.
