Hi, I'm Drew. Welcome to my fair trade, artisanally-crafted, gluten-free website! I am a postdoctoral associate at the Duke University Nicholas School of the Environment and an incoming assistant professor of environmental studies and sciences at Oberlin College; also, I have no trouble distinguishing my right from my left. Be aware that this website is very large, and some of it is randomly generated. For the full experience, reload a bunch of times and navigate as follows:

• If you are interested in my SCIENTIFIC WORK: In my scientific research, I use satellite data to track pollution back to its source and monitor emissions in real time, and I maintain free open-source software that allows others to do the same. If you want to learn more, check out out my ongoing projects, research papers, conference presentations, and environmental datasets. Everything is open access, and you can find a general-audience explanation of each of the publications I led in my newsletter.
• If you are interested in my INTERDISCIPLINARY WORK: My interdisciplinary work imagines how humanity can democratically govern itself in an age of environmental crisis. With collaborators, I imagine the sorts of institutions and protocols that advance economic democracy within planetary boundaries, with an emphasis on connecting science with (1) social movements and (2) economic planning. This work has taken the form of books, video games, public writing, and academic publications.
• If you are interested in MY CV: you can download it here.
• If you are interested in MISCELLANEOUS: This website is big because I have had it since high school and I don't delete things. If you search for it, you can find ephemera I have made over the years, including original music.
• If you are interested in HUMAN CONTACT: I can be reached at drew [at] drewpendergrass [dot] com or at the academic address in my CV. For upcoming events, check out my events page. You can follow me on Bluesky or LinkedIn. The best way to follow my work is to subscribe to my newsletter below (expect emails every six months or so at most):

Pendergrass, D. C., Jacob, D. J., Nesser, H., Varon, D. J., Sulprizio, M., Miyazaki, K., & Bowman, K. W. (2023). CHEEREIO 1.0: A versatile and user-friendly ensemble-based chemical data assimilation and emissions inversion platform for the GEOS-Chem chemical transport model. Geoscientific Model Development, 16(16), 4793–4810. Link to paper (open access). Link to PDF. Read a general audience explainer.

Figure: Schematic of CHEEREIO runtime routines and job control procedures. CHEEREIO is run as an array of m separate jobs on a computational cluster, one for each ensemble member. These m jobs, operating in parallel, alternate between running GEOS-Chem and running the LETKF algorithm for a subset of grid cells, as shown by the light yellow boxes; the m jobs are coordinated by a single job controller shared by the entire ensemble (shown in light red), ensuring that the ensemble remains synchronized. Boxes in blue show data input into CHEEREIO processes.

You can learn more about my research on the projects page, or you can read through all of our scientific papers and presentations on their respective pages.

All the cool kids are using CHEEREIO!

CHEEREIO is a tool that uses observations of pollutants in the atmosphere, measured from satellites or surface stations, to correct supercomputer models that simulate the Earth. Powerful use cases for CHEEREIO include tracking pollution back to its source, even if there are no local observations on the ground, and monitoring greenhouse gas emissions in near-real-time. Read more on my projects page or the offical CHEEREIO site.
