  • Closes Add aod and clearsky_index to glossary #2564
  • I am familiar with the contributing guidelines
  • Adds description and name entries in the appropriate "what's new" file in docs/sphinx/source/whatsnew for all changes. Includes link to the GitHub Issue with :issue:`num` or this Pull Request with :pull:`num`. Includes contributor name and/or GitHub username (link with :ghuser:`user`).
  • New code is fully documented. Includes numpydoc compliant docstrings, examples, and comments where necessary.
  • Pull request is nearly complete and ready for detailed review.
  • Maintainer: Appropriate GitHub Labels (including remote-data) and Milestone are assigned to the Pull Request and linked Issue.

Additional edit: fixed line length of some of the other definitions. Not strictly a flake8 failure but I think it looks neater and more readable.

@RDaxini RDaxini added this to the v0.14.1 milestone Jan 21, 2026

Sexy PR @RDaxini , thanks. Some observations down below, but I'm okay with current status as is.

aod
aod500
aerosol optical depth. Measure of aerosols (e.g., smoke
particles, desert dust) distributed within a column of air from the
instrument (Earth's surface) to the top of the atmosphere. The AOD
value indicates the level of extinction of sunlight in this column, and
when followed by a number (e.g. AOD500), indicates the extinction at
this wavelength (500nm). [unitless]

Is it described by these equations? https://en.wikipedia.org/wiki/Optical_depth#Spectral_optical_depth

I have trouble finding PV specific information on a mathematical relationship. At least that is the only missing piece for me.
