We have partnered with a number of local universities to work on various projects. The goal is to collect data and express it to the public in an engaging and informative way.

PurpleAir Sensor Installation

Dr. Cesunica Ivey
Xavier Gomez

With the contribution of 25 sensors by Dr. Ivey, and the help of Xavier Gomez and the Promatoras, we were able to install a number of new sensors throughout South San Francisco.

In addition to installing the sensors, Xavier considered the largely Spanish-only-speaking population of the city, many of whom didn't go to school beyond elementary. He made it a point to create easy-to-understand maps in both English and Spanish.

This map displays the average air quality between December 2022 and May 2023. He opted for color-coordinated smiley faces to communicate how good the air was to breathe, especially over a long period of time.

Here is the live PurpleAir Map that displays local air quality. You can interact with the map directly from this page, or you can visit it at You can find more information about Air Quality Index (AQI, which the map displays by default) on our Resources page.

Dr. Cesunica Ivey is an assistant professor in the Civil and Environmental Engineering Department at the University of California, Berkeley, and generously provided over 25 air quality sensors to Rise.

JieQi Yan

UC Davis

JieQi Yan, Graduate Student Researcher from UC Davis, created a vulnerability map containing sensitive receptor locations and high-risk areas of air pollution, incorporating data from sources such industry emissions, and on-road pollutants for the city of South San Francisco. The map aims to provide an initial glance of pollution intensity in spatial distribution.

Leanna Lewis
