How Poor Air Circulation Affects Indoor CO₂ Levels

When people think of air pollution, they often picture smoggy cities or factory emissions. But indoor air can degrade just as quickly, and one of the most overlooked culprits is carbon dioxide (CO₂). Indoors, CO₂ is primarily generated by people simply breathing. In a closed room with poor air circulation, CO₂ can accumulate rapidly, often … Read more

To accurately measure greenhouse gases (GHGs) in the field, scientists primarily rely on four categories of tools: nondispersive infrared (NDIR) spectroscopy, cavity ring-down spectroscopy (CRDS), flux-based instruments like eddy covariance towers and flux chambers, and remote sensing platforms including satellites and drones. Each method leverages the unique way GHG molecules absorb specific wavelengths of infrared … Read more
