Abstract

While CO₂ is the main greenhouse gas responsible for climate change, it is a well-mixed gas in the atmosphere, meaning that its concentration is relatively uniform and does not vary much over short distances. This makes it difficult to monitor CO₂ levels in specific regions or to detect changes in CO₂ concentrations at small scales. On the other hand, NO₂ is emitted from combustion sources that also emit CO₂, and its concentration varies greatly depending on proximity, making it a useful tracer for identifying emissions sources. Therefore, NO₂ is widely assumed to be a robust proxy for combustion CO₂ and provides additional, valuable information for CO₂ monitoring such as plume detection. The combination of NO₂ and CO₂ observations is useful in determining the exact locations and intensities of anthropogenic CO₂ emissions. The idea of the present study is to design a very compact instrument for NO₂ plume detection that allows easy accommodation of both CO₂ and NO₂ sensors on a single platform. Conceding on the need to explore internal dynamics of plumes and focusing more on the spatial evolution, NO₂ detection can then rely on a relaxed set of requirements, which has a beneficial impact on instrument size, thus leading to a miniaturized instrument. In the present paper the driving requirements of such a miniaturized instrument will be introduced, and a compact design will be presented. Benefits and complexities of a compact design will be discussed.
