vertical atmospheric profiles

Our interest is in sampling air quality in vertical columns from ground level to 1000' up. We are going to take advantage of our aerial mapping platform to lift sensors high above our cities and landscapes.

This project builds upon the open source "Air Quality Egg" project by the Internet of Things community.

Abstract

Balloons and kites are a proven delivery mechanism for launching cameras (grassrootsmapping.org) and simple sensors like temperature (http://cires.colorado.edu/). Public Laboratory for Open Technology and Science and Pachube will prototype a modular, adaptive system that incorporates a single balloon-mounted air quality sensor that can deliver real-time, altitude-specific data. The system will be able to collect vertical atmospheric profiles to shed light on phenomena such as the urban heat island and the CO2 dome. The original concept emerged from conversations with Craig Mills at the UNEP who envisioned a global mediagenic event of sensor-equipped balloons rising up across the planet.

The second step of this project will build on requests from member communities facing industrial pollution. Public Laboratory has been asked to assist with developing diagnostic air quality monitors that can identify the source (according to wind direction and speed) of the particulate matter and chemicals affecting community health. This step will include the incorporation of sensors for VOC, particulate matter, metal halides, and sulfur dioxide in addition to what the Pachube Air Quality Egg project already features, namely: carbon monoxide, nitrogen oxide, temperature and humidity.
