India's 'gas chamber' smog

India's 'gas chamber' smog

Author: Hugh Bollinger/Monday, November 13, 2017/Categories: natural history, space science, sustainability, environment, climate change

North India has been covered for over a week in a txoic shroud of smog so bad airlines are now choosing not to land in the capitol, New Delhi. The smog stretches in a broad band west into Pakistan and eastward into southern Nepal. The smog is being dubbed a 'gas chamber' of air pollution caused by a combination of foggy weather, smoke from illegal crop-residue burning mixed with dust and industrial pollution creating the very thick haze. Measurements of microscopic particulate matter, based on the EPA's Air Quality Index or PM-2.5 scale, are 100 times above the upper limit considered safe. New Delhi hospitals are being inundated with breathing victims.

NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) camera on the Aqua environmental moitoring satellite, captured the extent of the smog coverage in South Asia in early November.
