AQAI

AQAI is using the OpenAQ platform to develop a machine learning predictive model for air quality showing child population density against regions with pollutant concentrations above WHO-recommended limits.

AQAI is one of nine startups (out of 450 applicants) awarded investment funding from the UNICEF Venture Fund in 2022.

The Problem

Children are particularly susceptible to air pollution’s insidious effects. They breathe more rapidly than adults, taking in more polluted air. Due to having smaller bodies, they are proportionally exposed at higher levels. Their developing organs are more vulnerable to pollution. And due to their height, they are face level with pollutants that settle lower in the air and pollutants, such as vehicle exhaust, emitted close to the ground.

The Solution

Christina Last and Prithviraj Pramanik met working on air quality data for UNICEF, the UN agency responsible for providing humanitarian and developmental aid to children worldwide. Recognizing that they could apply data science to support children’s health, Prithviraj and Christina founded AQAI (based in India) to evaluate exposure to particulate matter in places where there is a low density of air quality sensors. The tool leverages artificial intelligence and machine learning, fusing together real-time satellite imagery and ground-based sensing to replace stale air quality data being used in health impact assessments. AQAI is working alongside UNICEF Belize and is exploring opportunities with UNICEF Mongolia to model pollution exposure for children and schools.

How OpenAQ Helped

According to Christina, “OpenAQ’s data aggregation platform has made our work possible. We ingest historic and real-time information from OpenAQ globally, allowing us to predict local pollution concentrations to inform our work with UNICEF country offices.” Prithviraj points out the harmonization and ease of data acquisition from OpenAQ via the API, which gave them the ability to focus more on downstream tasks rather than the tedium of looking for these data themselves. “Structured air quality data is hard to acquire from global agencies that follow diverse API structures for querying. When we initially started the exploratory data analysis, OpenAQ simplified the data acquisition from federal regulatory monitors.”
