This dataset contains PM2.5 and meteorology measurements taken from Temuco and Padre Las Casas, Chile from June 2017 to July 2018. This data was collected for the NERC funded project Impact of Wood Burning Air Pollution on Preeclampsia and other Pregnancy Outcomes in Temuco which aimed to determine whether exposure to air pollutants (specifically PM2.5 and wood burning tracer) have an impact on preeclampsia and other pregnancy outcomes (low birth weight, birth weight, small of gestational age, preterm birth). The purpose of this data is to predict the spatio-temporal PM2.5 concentrations and wood tracers using land use regression models.

The campaign included sampling at 40 fixed sites in parallel with sampling at a central site located at a government monitoring station to control for background levels. Sites tried to maximize the spatial distribution of likely predictors such as number of residential dwellings, number of wood-stoves, PM2.5 concentrations and traffic impact. Two-weeks PM2.5 samples were collected at each site and repeated in 4 sessions covering a whole year. Samples were analyzed for mass and the wood-burning tracers levoglucosan and soluble potassium.
