Discover TELLUS


TELLUS is recognized for our smart network deployments powered by TELLUS Coredi, our intuitive dashboard and reporting tools that make monitoring air quality simple and easy for everyone.

Expand your current network’s capabilities by applying TELLUS Coredi to your existing network. TELLUS integrates regulatory instruments and other sensors in your region and integrates the raw measurements using advanced modeling that relies on spatial statistics, and dynamic calibration factors for each location in your network.

Each sensor’s calibration factor is traceable back to government measurements, delivering the highest level of accuracy possible for the price.

It’s not about the NODES themselves, but the space between them

The AirView Map and Dashboard are your gateways to understanding air quality micro-climates and identifying pollution contributors through visualizations and alerts, keeping your community informed.

With AirView you can view and download raw and modeled air quality data to support data-driven decisions.

Innovative Technology

AirView© patented technology allows TELLUS to produce up-to-date and verifiable calibrations unique to each location that are directly traceable back to reference measurement instruments.

Government agencies produce maps based on very limited high-accuracy measurements that fail to capture local dynamics while low-cost alternative sensor networks typically provide inaccurate air quality measurements that are difficult to make sense of.

Whether you are a community organization or municipality interested in monitoring pollution and pollution contributors, TELLUS offers the most cost effective and accurate air quality monitoring visualizations without the burden of interpreting often-conflicting measurements that can be confusing to community members.

How does it work

AirU air quality monitors pull in ambient air using a low-powered fan. The air flows along a series of pathways into a chamber before the air is exhausted back into the atmosphere. Along the way, various sensors take samples of the passing air and these measurements are both uploaded to the TELLUS Cloud as well as written to its onboard SD card as a backup.

The data can be accessed remotely through your personal dashboard for further analysis and insights.

Data Integration Process

Measurements are collected from multiple organizations and 3rd party sources, such as local state agencies and the EPA. TELLUS provides a suite of data correction and machine-learning-based modeling techniques that are applied to non-regulatory measurements to provide the most accurate data available. Incoming measurements are first screened and flagged for outliers as they are logged in the TELLUS database.

Then, data is periodically scanned retroactively using sophisticated spatiotemporal filtering to find and flag potentially drifted measurements.

Finally, spatiotemporal models are provided for every study region making it possible for calibrated air quality estimates at any location and time.

AirView Powered by TELLUS Coredi

TELLUS Coredi is the culmination of over 15 combined years of rigorous multidisciplinary research, and numerous published papers, born out of the University of Utah. An initial grant in 2017 focused on high spatial resolution urban pollution monitoring that was both cost-effective, reliable, and intuitive; something that could feasibly be used by local organizations and municipalities with a high degree of trust. To accomplish this goal TELLUS developed a highly integrated, multi-tier hardware-software ecosystem that ensures the most accurate measurements and representation.

TELLUS uses a suite of statistical tools developed in-house and refined over the last five years using trillions of data points spanning multiple regions across the globe to screen for outliers and flag erroneous measurements in real time. TELLUS leverages the integration of 3rd party ground-truth data sources to continuously update in situ field calibrations to the network to correct for changing environmental conditions and ensure the most accurate and trustworthy data. TELLUS applies spatial statistics reliably provide pollution information between data sources(nodes) to provide pollution measurements anywhere in the network region.
