Air Quality

Atmospheric Infrared Sounder (AIRS) data have been used to track propagation of toxic gases like Carbon Monoxide (CO) from massive fires; accurate early warnings of such pollution spikes 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 Land, Atmosphere Near real-time Capability for EOS (LANCE) to improve some local and national air quality forecasts.

Potentially useful data sets: Moderate Resolution Imaging Spectroradiometer (MODIS) Aerosol, AIRS CO (total column) and Sulfur Dioxide (SO2) (day and night), OMI Aerosol Optical Depth, Absorbing Aerosol Optical Depth and Aerosol Index.

Visualize NRT data related to Air Quality in Worldview

Natural-color images of northeastern China on January 14, 2013. The image shows extensive haze, low clouds, and fog over the region. The brightest areas tend to be clouds or fog, which have a tinge of gray or yellow from the air pollution. Other cloud-free areas have a pall of gray and brown smog that mostly blots out the cities below. In areas where the ground is visible, some of the landscape is covered with lingering snow from storms in recent weeks. Read more at NASA's Earth Observatory.
