Correcting biases in regional climate model boundary variables for improved simulation of high-impact compound events

open access: yesiScience, 2023
Summary: Although climate models have been used to assess compound events, the combination of multiple hazards or drivers poses uncertainties because of the systemic biases present.

Agricultural burning monitored for air pollutants in Imperial County; exposure reduction recommendations developed

open access: yesCalifornia Agriculture, 2012
Air pollutants, notably particulate matter (PM) with aerodynamic diameter smaller than 2.5 micrometers (PM2.5), are emitted during agricultural burning. We studied a winter period in Imperial County when predominantly bermuda-grass stubble was burned. At

Development of multi-scale indices of human mobility restriction during the COVID-19 based on air quality from local and global NO2 concentration

open access: yesiScience, 2023
Summary: This study investigated whether variability in air quality, especially related to vehicular emissions, during the COVID-19 pandemic could indicate social distancing. Data from in situ measurements and satellite estimates were used.
