&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[https://www.cambridge.org/core/books/climate-change-2021-the-physical-science-basis/annex-vii-glossary/058768DADC00B52E2ED3381D0259B4E0 Climate Change 2021 – The Physical Science Basis, Annex VII: Glossary], written by the Intergovernmental Panel on Climate Change (IPCC) and published by Cambridge University Press in 2023, states in relation to aerosol optical depth (AOD): ‘Wavelength-dependent aerosol optical depth is a measure of the aerosol contribution to extinction of top-of-the-atmosphere solar intensity measured at the ground. AOD is unitless.’&lt;br /&gt;
&lt;br /&gt;
It defines fine-mode aerosol optical depth as: ‘Aerosol optical depth due to aerosol particles smaller than 1 μm in radius.’&lt;br /&gt;
