Detecting Greenhouse Gases: Key Wavelengths and Optical Technologies
Greenhouse gases (GHGs) are a significant driver of global warming, making their detection and monitoring critical for environmental protection and climate change mitigation. Understanding the specific wavelengths at which these gases absorb infrared radiation helps in designing effective detection systems.
