Low Cost Sensors AQ AirGradient Data
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/low-cost-sensors-aq/airgradient
Low-Cost-Sensors-AQ_AirGradient is the ground site data collected by the AirGradient sensor network as part of the Low-Cost Air Quality Sensor Harmonization Database.
Description
Data collection for this product is ongoing. The Low-Cost Sensor AQ Harmonization aims to harmonize sensor networks by amalgamating measurements from a multitude of networks into one open access framework.
Currently, data from 10 unique US-based sensor networks have been collected for redistribution in the archive. Data from each network is reformatted in a common data format with metadata embedded to streamline data processing. A key feature is a tier system in which the team critically reviews each sensor network by their calibration efforts and subsequent data quality, providing data quality flags to help end users determine which sensor data best meets their target application.

The framework allows users to search based on calibration criteria in addition to location, date range, and pollutant of interest. The sensor database is aimed at scientific end users seeking ground-based validation data for satellites and models alike but is also accessible to community scientists. The team is currently accepting new submissions!
