Our public OpenMap platform visualizes PM2.5 and Air Quality Index (AQI) data from Clarity's rigorously calibrated Node-S air quality sensors alongside vetted government reference monitors. Get hourly NowCast AQIs, daily and monthly averages, and more, all with complete transparency on data sources and methodology.
Once your network is up and running, you’ll have the option to share your data to Clarity’s public OpenMap platform. View, plot, and share data in an open repository with a built-in checkbox in the Clarity Dashboard. With one click, you’re able to add your data to the public map and ensure it can be accessed.
For hourly data from Clarity Nodes and Reference Monitors, we display the PM2.5 NowCast AQI. The NowCast AQI is an index developed by the US Environmental Protection Agency (US EPA) to estimate air quality conditions during a given hour, using a weighted-average of the past several hours of pollutant concentration data. The exact number of hours used is dependent on the variability of concentrations. Read more about EPA’s NowCast methodology here.
For daily data from Clarity Nodes and Reference Monitors, visible when viewing monthly or annual plots, we are displaying PM2.5 24-hour mean AQI, calculated using PM2.5 24-hour mean concentration. Data from the government reference network is being added to OpenMap through three sources: the AirNow, the European Environment Agency (EEA) and OpenAQ.
OpenMap access is part of Clarity's Sensing-as-a-Service air quality monitoring solution, which includes:
Self-powered Clarity Node-S air quality monitoring hardware measures PM2.5 and NO2 and serves as a platform for additional modules that measure Wind, Black Carbon, and Ozone. Rugged and with minimized maintenance requirements, our devices reduce installation and field intervention costs.Explore our devices
Air quality measurements and air sensor network status are easily accessible in real-time via Clarity’s user-friendly Dashboard, REST API, and OpenMap. No matter your level of experience, we have a solution to help you and your project’s stakeholders to get the most out of your data.Learn more about Clarity Cloud
Air quality monitoring is hard, but we can help. You’ll partner with an experienced Environmental Project Manager to help you define a project plan and guide you through Collocation and Calibration of your devices. You’ll receive support throughout the duration of your project, with recurring meetings and check-ins to ensure data quality.
