Accurate early warnings of poor air quality are useful because they give people the option to reduce their risk of exposure to poor air by limiting outdoor activity at these times. Air quality forecasters use near real-time (NRT) data from NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) to improve some local and national air quality forecasts. Users can visualize imagery related to Air Quality in Worldview or download data using the links below.

The skies over the Indo-Gangetic Plain - a river valley that includes parts of Pakistan, India, Nepal, and Bangladesh - are among the haziest in the world. Those four countries regularly come in near the bottom of annual rankings for air quality. As described an article from NASA's Earth Observatory - Seasons of Indian Air Quality, air quality varies throughout the year. This image shows a dust storm obscuring most land features. In October and November numerous agricultural fires from crop-burning cause large smoke plumes lingering downwind.
