Autor: Weissert, Lena, Miles, Elaine, Miskell, Georgia, Alberti, Kyle, Feenstra, Brandon, Henshaw, Geoff S, Papapostolou, Vasileios, Patel, Hamesh, Polidori, Andrea, Salmond, Jennifer A, Williams, David E

We present a management and data correction framework for low-cost electrochemical sensors for nitrogen dioxide (NO2) deployed within a hierarchical network of low-cost and regulatory-grade instruments. The framework is founded on the idea that it is

Low-cost sensor networks and land-use regression: interpolating nitrogen dioxide concentration at high temporal and spatial resolution in Southern California

Autor: Weissert, Lena, Alberti, Kyle, Miles, Elaine, Miskell, Georgia, Feenstra, Brandon, Henshaw, Geoff S, Papapostolou, Vasileios, Patel, Hamesh, Polidori, Andrea, Salmond, Jennifer A, Williams, David E

The development of low-cost sensors and novel calibration algorithms offer new opportunities to supplement existing regulatory networks to measure air pollutants at a high spatial resolution and at hourly and sub-hourly timescales. We use a random fo

Hierarchical network design for nitrogen dioxide measurement in urban environments, part 1: proxy selection

Autor: Weissert, Lena, Miskell, Georgia, Miles, Elaine, Alberti, Kyle, Feenstra, Brandon, Patel, Hamesh, Papapostolou, Vasileios, Polidori, Andrea, Henshaw, Geoff S, Salmond, Jennifer A, Williams, David E

Previous studies have shown that a hierarchical network comprising a number of compliant reference stations and a much larger number of low-cost sensors can deliver reliable air quality data at high temporal and spatial resolution for ozone at neighb

We demonstrate how a hierarchical network comprising a number of compliant reference stations and a much larger number of low-cost sensors can deliver reliable high temporal-resolution ozone data at neighbourhood scales. The framework, demonstrated o
