The use of hierarchical clustering for the design of optimized monitoring networks [PDF]
Atmospheric Chemistry and Physics, 2018 Associativity analysis is a powerful tool to deal with large-scale datasets by clustering the data on the basis of (dis)similarity and can be used to assess the efficacy and design of air quality monitoring networks.

A three-dimensional-model inversion of methyl chloroform to constrain the atmospheric oxidative capacity [PDF]
Atmospheric Chemistry and Physics, 2021 Variations in the atmospheric oxidative capacity, largely determined by variations in the hydroxyl radical (OH), form a key uncertainty in many greenhouse and other pollutant budgets, such as that of methane (CH4).
