Daniel Varon

Visiting Postdoctoral Research Associate

I'm an atmospheric chemist focusing on satellite remote sensing of atmospheric composition. I received my PhD in atmospheric chemistry from Harvard University in 2020 along with an MSc in applied mathematics. My research revolves around satellite monitoring of greenhouse gas emissions and air quality pollution, from global and regional scales down to the level of individual point sources. I'm interested in using the expanding satellite observing system to help generate environmentally actionable information in support of policy on air quality and climate.
