Mobile monitoring of urban air quality at high spatial resolution by low-cost sensors: impacts of COVID-19 pandemic lockdown

The use of electrochemical sensors for monitoring urban air quality in low-cost, high-density networks

Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring spatially heterogeneous environmentswith complex andhighlyvariable emission sources, such as inurban areas. However, the costs and complexity of conventional air quality measurement methods means that measurement networks are generally extremely sparse. In this paper we show that miniature, lo...

Mitigating Slow Dynamics of Low-Cost Chemical Sensors for Mobile Air Quality Monitoring Sensor Networks

The last decade has seen a growing interest in air quality monitoring using networks of wireless low-cost sensor platforms. One of the unifying characteristics of chemical sensors typically used in real-world deployments is their slow response time. While the impact of sensor dynamics can largely be neglected when considering static scenarios, in mobile applications chemical sensor measurements...

The Impacts of ICT on Urban Travels: A Significant Shift during the Covid-19 Pandemic

Transportation is one of the most important issues in today's cities. Urban trips and their spatial and temporal patterns influence and are influenced by other components and functions of the city. Information and communication technology have evolved rapidly over the last few decades and have influenced urban travel patterns in many ways. Numerous studies have attempted to study the effects of...

The effect of COVID-19 lockdown on the air environment in India

COVID-19 is a huge tragedy for the world community. Everything in the world is affected due to this pandemic right from economy to resources where the economy of major countries of the world are facing recession and resources are surplus with no takers at all. The measures to contain COVID-19 pandemic include lockdown, social distancing, isolation, and home quarantine. Lockdown adopted by the d...
