Spatiotemporal Resolution

<p>Air pollution and extreme weather patterns have become serious issues over the world, especially in highly urbanized areas.  In order to detailed study the atmospheric environmental change, the capability to perform high spatiotemporal resolution atmospheric environmental data collection is highly desired.  In this research, we develop a cost-effective air quality monitoring system based on as open-source electronics platform (Arduino Uno Rev3) with multiple environmental sensing modules including particulate matter (PM) concentration, temperature, humidity, and sound sensors.  An integrated monitoring system with one weather station (precipitation and wind sensors) and two sets of environmental sensors set up in different heights from the ground costs less than USD$300.  The entire system is powered by a battery for portability, and all the data can be stored in a secure digital (SD) memory card for long-term monitoring. The cost-effectiveness makes it feasible for large-scale field tests with three-dimensional (3D) spatial resolution.  In the experiments, the system is tested in urban areas, and the data collection performance has been confirmed.  The results show that the data with single minute resolution can be successfully achieved in real-world scenarios with high air temperature (> 38<sup>o</sup>C) and rain conditions for more than 65 hours with a single-time battery setup.  In addition, the data collected from different heights have shown distinct atmospheric environmental patterns suggesting that it is critical to perform 3D high spatiotemporal measurement and modeling for city-scale studies.</p>

AbstractAn electronic nose that uses an array of 32 polymer–carbon black composite sensors has been developed, trained, and tested. By selecting a variety of chemical functionalities in the polymers used to make sensors, it is possible to construct an array capable of identifying and quantifying a broad range of target compounds, such as alcohols and aromatics, and distinguishing isomers and enantiomers (mirror-image isomers). A model of the interaction between target molecules and the polymer–carbon black composite sensors is under development to aid in selecting the array members and to enable identification of compounds with responses not stored in the analysis library.

Monitoring Stations

A sensors network based on 8 stationary nodes distributed in Bari (Southern Italy) hasbeen deployed for urban air quality monitoring during advection events of Saharan dust in theperiod 2015–2017. The low-cost sensor-systems have been installed in specific sites (buildings,offices, schools, streets, airport) to assess the PM10 concentration at high spatial and temporalresolution in order to supplement the expensive official air monitoring stations for citizen sciencepurposes. Continuous measurements were performed by a cost-effective optical particle counter(PM10), including temperature and relative humidity sensors. They are operated to assess theperformance during a long-term campaign (July 2015–December 2017) of 30 months for smart citiesapplications. The sensor data quality has been evaluated by comparison to the reference data of the9 Air Quality Monitoring Stations (AQMS), managed by local environmental agency (ARPA-Puglia)in the Bari city.
