The use of hierarchical clustering for the design of optimized monitoring networks [PDF]

open access: yesAtmospheric 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.

Quantification of major particulate matter species from a single filter type using infrared spectroscopy – application to a large-scale monitoring network [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
To enable chemical speciation, monitoring networks collect particulate matter (PM) on different filter media, each subjected to one or more analytical techniques to quantify PM composition present in the atmosphere.

A three-dimensional-model inversion of methyl chloroform to constrain the atmospheric oxidative capacity [PDF]

open access: yesAtmospheric 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).
