Why “Perfect” Infrared Spectrometers Are a Myth – and Why That Matters for Atmospheric Measurements

Modern atmospheric science relies on precise and stable measurements to understand how the composition of the atmosphere evolves over time. From air quality to climate-relevant trace gases, long-term observations are essential for identifying trends and detecting subtle changes. One of the key tools enabling such measurements is infrared spectroscopy, which allows scientists to identify and …[Read More]
