The surface pressure doesn't tell you anything what's going on at height?

Where did you learn that?

You are stuck in your two dimensional world on the ground or at sea level.

I fly in a three dimensional world in the atmosphere.

One big breakthrough a few years after I received my FAA pilots license in 1974 while in college was the development of ACRS, and shortly thereafter ABO.

ACARS

Aircraft Based Observations AMDAR (ABO)

amdar.noaa.gov

Virtually all commercial jet transport aircraft today have both services transmitting their current wx information about once a second, altitude, Lat Lon, absolute barometric pressure info corrected via GPS, temp, humidly, true wind direction and speed and other weather info.

Many light aircraft today also have those capabilities, biz jets, turboprops ect.

Vastly more information than what's available from surface observations.

And all of that data moves real time to various weather services around the world! Via satellite, VHF, UHF, or HF.

We now have some very high resolution data in real time of the atmosphere, once every second.

Absolutely priceless data that greatly increases forecast accuracy.

Not just at ground level!
