Projects

In addition to publishing our findings in peer-reviewed journals, we maintain open-source software called CHEEREIO used by research groups around the world to quantify emissions of greenhouse gases and air pollutants. We also publish large high resolution pollution maps for use in public health studies, regulation, and other applications. See below for our projects.

Continuous 2011-2022 PM2.5 in East Asia at daily 2-km resolution
Continuous 2011-2022 PM2.5 in East Asia at daily 2-km resolution

We construct a continuous 24-h daily fine particulate matter (PM2.5) record with 2×2 km2 resolution over eastern China, South Korea, and Japan for 2011-2022 by applying a random forest (RF) algorithm to aerosol optical depth (AOD) observations from the Geostationary Ocean Color Imager (GOCI) I and II satellite instruments
