Are Neural Networks Really the Holy Grail? A Comparison of Multivariate Calibration for Low-Cost Environmental Sensors
TL;DR: This work used a six-months worth of real hourly data to demonstrate that the ANN may not always be the best choice of a calibration method, and suggests that the performance of a calibrated method can be more sensitive to some of the factors than the use of different calibration methods.

Assessing the Climate Change-Related Health Hazards in Africa
TL;DR: In this paper , the authors assess the climate change-related health hazards that Africa faces and will face in the future through literature synthesis from various sources and indicate that the burden of disease from climate changerelated ailments is likely to increase for the majority of African countries moreso for those countries with already vulnerable health delivery systems, poor health policies, and poor health infrastructure.

Enhancing reliability of particulate matter sensing by multivariate Tobit model using weather and air quality data
TL;DR: In this article , a multivariate Tobit model with historical weather and air quality data is proposed to improve the accuracy of ambient air monitoring, which is highly dependent on meteorological conditions, local climate, and regional PM properties.

TL;DR: It is shown that miniature, low-cost electrochemical gas sensors can, when suitably configured and operated, be used for parts-per-billion level studies for gases relevant to urban air quality, and that measurement networks with higher resolution are required to quantify air quality at the scales which are present in the urban environment.
