NASA's AIRS maps carbon monoxide from Brazil fires
This time series shows carbon monoxide associated with fires from the Amazon region in Brazil from Aug. 8-22, 2019. Made with data collected from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite, the images map carbon monoxide at approximately 18,000 feet (5,500 meters) altitude. Each "day" in the series is made by averaging three day's-worth of measurements. Credit: NASA/JPL-Caltech

New data from NASA's Atmospheric Infrared Sounder (AIRS) instrument, aboard the Aqua satellite, shows the movement high in the atmosphere of carbon monoxide associated with fires in the Amazon region of Brazil.

This time series maps carbon monoxide at an altitude of 18,000 feet (5,500 meters) from Aug. 8-22, 2019. As the series progresses, the carbon monoxide plume grows in the northwest Amazon region then drifts in a more concentrated plume toward the southeastern part of the country.

Each "day" in the series is made by averaging three days' worth of measurements, a technique used to eliminate data gaps. Green indicates concentrations of monoxide at approximately 100 parts per billion by volume (ppbv); yellow, at about 120 ppbv; and dark red, at about 160 ppbv. Local values can be significantly higher.

A pollutant that can travel large distances, can persist in the atmosphere for about a month. At the mapped in these images, the gas has little effect on the air we breathe; however, can carry it downward to where it can significantly impact air quality. Carbon monoxide plays a role in both air pollution and .

AIRS, in conjunction with the Advanced Microwave Sounding Unit (AMSU), senses emitted infrared and microwave radiation from Earth to provide a three-dimensional look at Earth's weather and climate. With more than 2,000 channels sensing different regions of the atmosphere, the instruments create a global, three-dimensional map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations and many other atmospheric phenomena.
