Dataset associated with "Emissions and radiative impacts of sub-10 nm particles from biofuel and fossil fuel cookstoves"
The dataset includes (i) measurements of particle emissions from several different cookstoves performed during a water boiling test and (ii) atmospheric concentrations and impacts from simulations performed with a global chemical transport model. These data need to be archived alongside an accepted...

The dataset includes (i) measurements of particle emissions from several different cookstoves performed during a water boiling test and (ii) atmospheric concentrations and impacts from simulations performed with a global chemical transport model. These data need to be archived alongside an accepted manuscript in Aerosol Science and Technology. The cookstove measurements were performed in Fall of 2018 and Spring of 2020. The model simulations were performed in Fall of 2019. Combustion sources have been shown to directly emit particles smaller than 10 nm. The emission of 1-3 nm particles from biofuel or fossil-fuel cookstoves has not been studied previously, nor have the radiative impacts of these emissions been investigated. In this work, emissions (number of particles) were measured during a water boiling test performed on five different cookstoves (three-stone fire, rocket elbow, gasifier, charcoal, and liquified petroleum gas [LPG]) for particle diameters between ~1 and ~1000 nm. We found significant emissions of particles smaller than 10 nm for all cookstoves (>5×1015 # kg-fuel-1). Furthermore, cleaner (e.g., LPG) cookstoves emitted a larger fraction of sub-10 nm particles (relative to the total particle counts) than traditional cookstoves (e.g., three-stone fire).
