Internship with CMU CREATE Lab

I've been working on visualizing air pollution, specifically smell reports and sensor data, on the CREATE lab's Earthtime data visualization tool (although some of the changes are not yet up on the public live site: https://earthtime.org/explore).

Skills used: Javascript, JQuery, CSS, HTML, Python Flask, WebGL, Ruby

The triangles are smell reports and circles are from sensor data. With the timeline, we can try to track where air pollution moves throughout the day, and which communities are affected. The colors are based on the official EPA air quality scale.

This visualization is paired with modeled particle plumes to make it easier to understand, and hopefully possible to predict how air quality will change through out the day. Right now this work is based in Pittsburgh, PA, but there is some data from Frankfurt, Kentucky.

The last large feature I added was a calendar to dynamically display data from different time ranges. This way, it is easy to compare pollution on different days, months, and years. The wind direction indicators were a simple addition. The data was fetched web server I built that interfaces with multiple databases to aggregate data into one file.
