Fix typo in equation 8a in “Mapping potential surface contributions to reflected solar radiation”

[bsmoliak]

Describe the bug

A minor typo was identified in equation 8a in the journal article, “Mapping potential surface contributions to reflected solar radiation.” T is missing from the numerator. The typo was propagated from Stephens et al. 2015. It affects the readability and accuracy of the equation as presented.

Stephens et al. (2015) - contains typo

Smoliak et al. (2022) - propagated typo

Li et al. (2024) - did not propagate typo

Expected behavior

A factor of T exists in the numerator of the fraction that computes t.
