Ground- and satellite-based observations of column nitrogen dioxide: instrument performance, column-to-surface relationships, and the role of meteorology in coastal urban environments
… lifetime, and the limited spatial extent of surface monitoring networks. In lieu of comprehensive surface monitoring, space-based retrievals of NO2 abundance may address gaps in our understanding of its spatiotemporal variability. Space-based observations of NO2, however, have …

Bayesian spatio-temporal modelling for forecasting ground level ozone concentration levels
… quality information is from measurements made at surface monitoring stations across a study region of interest. Typically, however, air monitoring sites are sparsely and irregularly spaced over large areas. That is why, it is now very important to develop space-time models for air pollution which …

Determining ground-level composition and concentration of particulate matter across regional areas using the Himawari-8 satellite
… wildfires and other aerosol emissions. Globally, surface monitoring is limited due to cost and infrastructure demands. While remote sensing can help estimate respirable (i.e. ground level) concentrations, current observations are restricted by inadequate spatiotemporal resolution, uncertainty in …
