COVID-19 caused a historic collapse in fossil fuel demand, a general decline in economic activity, and hydrocarbon price volatility. This resulted in an unprecedented scenario to evaluate the contribution of the O&amp;G (Oil and Gas) industry NO<sub>2</sub> (nitrogen dioxide) emissions in the Permian basin (United States), currently the...

Nitrogen dioxide (NO<sub>2</sub>) is a potential hazard to human health at low concentrations, below one part per million (ppm). NO<sub>2</sub> can be monitored using gas sensors based on multi-layered graphene operating at ambient temperature. However, reliable detection of concentrations on the order of parts per million and lower is...

The problem for which solutions are proposed in this report is ambient air pollution, which causes health risks for people living indoors worldwide. This research focuses on the two Major Air Pollutants nitrogen dioxide and particulate matter, that cause the most problems now and in the future.<br/><br/>The starting point of this research is to...

In this work, we present the development of a 4D-Ensemble-Variational (4DEnVar) data assimilation technique to estimate NOx top-down emissions using the regional chemical transport model LOTOS-EUROS with the NO2 observations from the TROPOspheric Monitoring Instrument (TROPOMI). The assimilation was performed for a domain in the northwest of...

TROPOspheric Monitoring Instrument (TROPOMI), on-board the Sentinel-5 Precurser satellite, is a nadir-viewing spectrometer measuring reflected sunlight in the ultraviolet, visible, near-infrared, and shortwave infrared. From these spectra several important air quality and climate-related atmospheric constituents are retrieved, including nitrogen...

The sp<sup>2</sup> carbon-based allotropes have been extensively exploited for the realization of gas sensors in the recent years because of their high conductivity and large specific surface area. A study on graphene that was synthetized by means of a novel transfer-free fabrication approach and is employed as sensing material is herein...

The sensing behavior of monolayer tin sulfide (SnS) for four gas molecules (NH<sub>3</sub>, NO<sub>2</sub>, CO, and H<sub>2</sub>O) are studied by the first-principle calculation based on density-functional theory. We calculate adsorption energy, adsorption distance, and Hirshfeld charge to estimate the adsorption ability of monolayer SnS for...
