Brown carbon (BrC) constitutes a significant portion of organic (OC) and exerts substantial influence on air quality, atmospheric chemical processes, the impact climate dynamics. The intricate chemistry BrC arises from multiple mechanisms source types, yielding wide spectrum spectral properties. Consequently, identifying representative chromophore species to develop reference material is crucial capture full diversity found in atmosphere ensure its precise monitoring. This also emphasizes need for more comprehensive measurement method link BrC's optical traits with composition. One objectives this review evaluate existing level understanding concerning molecular compositions compounds by analyzing recent field laboratory data. paper revises expands part prior database containing critical assessments primary secondary sources, photochemistry multi-phase reactions involving BrC, potential candidate chromophores, studies properties cryosphere, draw lessons advances that lead improved representation atmosphere.
