Hi, I'm Drew Pendergrass. My GMO-free, boneless, low-sodium website is lovingly built from whatever I decide to post online. It hosts a variety of projects, resources, and ephemera made over the years, including a book, video games, open-source software for assimilating satellite observations of pollution, environmental datasets, my writing, experimental music, a fake startup that sells logs on wheels, as well as my research papers and conference presentations in atmospheric science and related fields.
Currently, I am a doctoral student in Environmental Engineering at Harvard University, studying under Daniel Jacob, and I freelance on the side for publications including Harper's and The Guardian. More importantly, I am not to my knowledge a victim of a mummy's curse, to my knowledge, there is no portrait of me that ages in my place, and I am not a closed, non-orientable, boundary-free manifold.
I can be reached at drew [at] drewpendergrass [dot] com, or at the academic address in my CV.
The latest science!
Pendergrass, D. C., S. Zhai, J. Kim, J-H. Koo, S. Lee, M. Bae, S. Kim, H. Liao, and D. J. Jacob. (2022). Continuous mapping of fine particulate matter (PM2.5) air quality in East Asia at daily 6x6 km2 resolution by application of a random forest algorithm to 2011-2019 GOCI geostationary satellite data. Atmospheric Measurement Techniques, 15, 1075–1091. PDF. Publisher's version (open access). Associated dataset available from Dataverse. Video of 15-minute oral presentation at AGU.
Figure: Daily PM2.5 concentrations during a pollution event in the North China Plain, around Beijing (December 16-21, 2016). Predictions from the random forest algorithm (background, on 6x6 km2 grid scale) are compared to observations made on the ground (circles). We see that the model is able to reproduce even this extreme level of pollution.

Some reflections on moving out of college early due to COVID-19: "Losing a Chair."
A Brief Q&A
Q. Why does this page keep changing?
A. This page is randomly generated by the server on each load. Most of the page's contents are not displayed on one particular load, so for the full experience reload a bunch of times.
Q. Why don't you just host this crap on Github like a normal person?
A. Github only allows static websites. I wanted my website to be different for every visitor. DrewPendergrass.com, like life itself, must always be in flux. You could say I'm an artist.
Q. Who are you?
A. Well, to start off, I have never commanded an army composed of more than 100,000 soldiers, I did not orchestrate the Camp David Accords, I am not a substitute for a medical doctor, I keep the old gods, and I am not reptilian. If you for some strange reason would like to know something substantial about me, you can check out my projects page or my CV.
Q. How can I contact you?
A. You can follow/DM me on Twitter, but I'm trying to stop using it so much, so it's best to email me at drew [at] drewpendergrass [dot] com (or the academic address in my CV). However, if your email is unpleasant, you should direct it to grievances@drewpendergrass.com, an inbox I definitely read.

Some true statements
A Moving, and Random, Quotation
We are all of us more mystics than we believe or choose to believe – life is complicated enough as it is, after all. We have seen more than we let on, even to ourselves.
Through some moment of beauty or pain, some sudden turning of our lives, we catch glimmers at least of what the saints are blinded by; only then, unlike the saints, we tend to go on as though nothing has happened. To go on as though something has happened, even though we are not sure what it was or just where we are supposed to go with it, is to enter the dimension of life that religion is a word for.

Three Cryptic Messages Regarding Matters of Supreme Importance
- Now redact your slogans before they corrupt your captors.
- All neighbors have been eliminated. Please surrender the morals.
- The gods will be purged.
One randomly-generated sorting algorithm, please!
Do you have an unsorted list of N natural numbers? Do you just hate it when programs are guaranteed to terminate? Do you get angry when algorithms do better than factorial time? Then you're in luck! The following algorithm has been generated just for you:
- Feed your list into a black hole, permanently destroying the information. The list is as good as sorted now! If people shake their heads and insist you actually sort the list, just generate a new one and proceed to the next step.
- Uh oh! You've triggered a penalty step. Before you proceed, you must perform a task. Andrew Wiles's proof of Fermat's Last Theorem is 109 pages long. Assuming each page contains roughly 2000 characters, the text can be encoded in order 1,000,000 bits. Generate this number of bits and check to see if they prove Fermat's Last Theorem. If they do not, repeat this step. If they do, proceed! You've paid the penalty. (This step was defined in collaboration with Mirac Suzgun).
- Produce N blockbuster action films, each with an advertising budget proportional to a number in the list. For consistency, ensure each film is released in the same theaters at the same time of year. (Practically, this means the list cannot exceed a dozen or so items. If N>12, simply delete all but twelve items from the list). Read off the box office earnings for each film in order, printing the number corresponding to each.
Congratulations! Your list is now sorted. You can find a permalink to this particular algorithm here.
