Queens Air Quality Sensor Pilot (February - November 2024)
This dataset is from an air quality monitoring pilot in Maspeth, Queens between February and November 2024 as part of the NYC Office of Technology and Innovation's (OTI) Smart City Testbed program (https://testbed.cityofnewyork.us/). The Office of Technology and Innovation (OTI) partnered with the Department of Health and Mental Hygiene (DOHMH) to pilot Clarity Node-S air quality monitoring sensors (https://www.clarity.io/products/clarity-node-s) in order to evaluate their performance and generate real-time environmental data. The pilot also tested PAMARES model air quality improvement devices from StaticAir (https://www.staticair.com) to assess their effectiveness in reducing particulate matter in targeted areas. By combining continuous monitoring with physical air quality interventions, the initiative aimed to determine both the reliability of the sensor technology and the measurable impact of the air purification devices in urban settings.

Columns
Each source column, with the name and type we use to store it.
0 of 12 columns carry a concept; 12 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
| Source field | Display name | What the publisher says it is | Concept | Source type | Stored as | Stored type | Row identifier | Unit |
|---|---|---|---|---|---|---|---|---|
:@computed_region_92fq_4b7q | City Council Districts | This column was automatically created in order to record in what polygon from the dataset 'City Council Districts' (92fq-4b7q) the point in column 'latitude_longitude' is located.
