AAAR 2022

The 2022 American Association of Aerosol Research conference is set to take place in Raleigh, North Carolina from October 3rd - 7th, 2022. If you're attending and interested in learning about how QuantAQ's professional-grade air quality sensors can be used to understand building ventilation, sources of urban air pollution, or

Can your Plantower PMS5003-based Air Quality Sensor Measure PM10?

No. Let's investigate. The Plantower PMS5003 is a low-cost particle sensor that does a (very) good job measuring the total scattered light for particles that are able to physically make it to the sensing area of the device. The peer-reviewed literature has shown the PMS5003 is unable to detect particles

Use py-smps to analyze size-resolved particle sensor data

py-smps is an open-source python package to help analyze and visualize data from aerosol sizing instruments such as the Scanning Mobility Particle Sizer (SMPS), Scanning Electrical Mobility Spectrometer (SEMS), and other aerosol-sizing instruments such as optical particle counters (OPCs). While it was originally developed to analyze data from research-grade instrumentation,

Rebasing time series in python

Quite often, you may find yourself with two sets of data - both time series - that do not share the same time index. There are a couple of common use cases where this may arise in air pollution/atmospheric chemistry: 1. You have two instruments that collect data at

Hello, Air Quality World!

Hello, Air Quality World!

Welcome to the QuantAQ blog! We founded QuantAQ in 2019 as a spinout of MIT and Aerodyne Research, Inc. We realized that the most efficient path to obtaining ubiquitous air quality monitoring was to move our research outside academia and build a team to combine modern computational data science with
