Atmospheric thickness

Is there a tool or graph that shows the thickness of the atmosphere at
various elevations and accounts for the altitude of the observatory?

There's the US Standard Atmosphere model. Give it an altitude and it
will return the density, pressure and speed of sound. References are
on Wikipedia.

I do not see any on Wikipedia links that have an input.

Google "standard atmospheric density profile",
3.5 milion answers.

But there are graphs at Wikipedia. As well as on other sites.

Looking at what elevation above the horizon?

It seems what I'm after is misinterpreted. I was talking with a friend
about some variable star work he does at his domed observatory. Somehow
I asked him at what is the lowest elevation he surveys. He said 30
degrees, about two atmospheres of thickness. He then said," maybe near
the horizon, it's 47 thickness." That's what I'm looking for.

How many thickness of atmosphere will I see from zero to ninety degrees
above the horizon.

================================================== ===========

Straight up (90 degrees) one atmosphere from sea level, less on a mountain top.

As you tilt over, 45 degrees gives you sqrt( 1 atm ^2 + 1 atm ^2) = 1.414
atmospheres by Pythagoras.
At 30 degrees, sin (30) = 0.5, so two atmospheres.
At zero degrees (telescope pointed at the horizon) you need to take into
account the curvature of the Earth, but I don’t waste any more time on a
useless lazy twerp that wants it all handed to him on a plate so that he can
argue the point.

Read what I have to say at my 12:05 pm (rewrite) post. Elevation, as in
elevation above the horizon, or as in az/el.
