The way "I see the diagram" it looks weird, but it is probably correct. My perception is that it is about frames of reference. We are used to seeing the Earth with Earth's north at the top, not at 23.5 deg from the vertical. This picture has the ecliptic pole at the top. As you state, Earth's equator matches the celestial equator. The Earth's poles would ...

As others have said, a single set of coordinates gives a point rather than an area. However, I assume that the intent of the question is an understanding of the precision of these coordinates - i.e. what's the area covered by the 1"x1" shape comprising all of the lat and lon values that would round to a whole number of seconds. The answer to that is "it ...

A point do not have an area. A point is a 0-dimensional mathematical object which can be specified in n-dimensional space using an n-tuple (x1, x2, ..., xn) consisting of n coordinates. The area of a point cannot be calculated. So the area must be null.

$\color{blue}{\text{The answer here presumes that Earth is a sphere.}}$ $\color{blue}{\text{This is not fully true, but the question seems to build in that assumption.}}$ $\color{blue}{\text{That should be clarified to determine if this answer is relevant.}}$ Do not use a 2D-plane which does not generally exist for four points. Use a tetrahedron. You can ...

I have two solutions. Use MetPy to calculate the height from the geopotential height. Use the hypsometric equation, averaging the temperature below the level.

If I understood the question right: CDO can interpolate from model level to height level with the operator ml2hl infile.nc outfile.nc additionally, for the lower atmospheric levels, you can add an extrapolation option. BUT I don't recommend it since its extrapolation performance is questionable.

As I see it, the Earth is well oriented, but due to (over)simplification the drawing of the geographical features may be misleading. The aspects that show that the North Pole is not upwards but tilted to the right are: The Mediterranean sea extends basically in an East-West direction. The (simplified) Mediterranean here is clearly tilted and not horizontal. ...
