Is it true that the composition of Earth's air is chemically homogeneous throughout the homosphere?

The chemical composition of the homosphere being relatively uniform due to constant turbulent mixing is a well-established textbook fact of atmospheric science that does not require citation.

The analysis

The claim states that Earth's air composition is chemically homogeneous throughout the homosphere (due to turbulent mixing). This is a well-established and basic scientific fact about the atmosphere's structure (the homosphere is defined precisely by this chemical homogeneity, unlike the heterosphere above it). According to the prompt instructions, a statement that is trivially true by definition or direct scientific observation is common knowledge, meaning no citation is needed and the balance verdict should be COMMON_KNOWLEDGE.
