This video has air quality data gathered by Valarm for a study described here: [ Ссылка ] . The Valarm app ( [ Ссылка ] ) running on a phone collected this sensor and volatile organic compounds (VOC) air quality data walking around the University of Southern California (USC) in downtown Los Angeles, California.

The Valarm Tools site ( [ Ссылка ] ) is used to download the data in KML format, which is visualized here in Google Earth. Here is a step-by-step do-it-yourself (DIY) tutorial for putting your Valarm data into Google Earth: [ Ссылка ] .
