NASA AIRS maps carbon monoxide from Brazil fires



New data
from the NASA Atmospheric Infrared Sounder (AIRS) aboard the Aqua
Satellite, shows the movement high in the atmosphere of carbon monoxide connected
with fires in the Brazilian Amazon.

This time
Series maps carbon monoxide at an altitude of 18,000 feet (5,500 meters)
8-22nd August 2019. As the series progresses, the carbon monoxide cloud grows
The northwestern Amazon region then drifts in a concentrated cloud towards the
southeastern part of the country.

each
"Day" in the series is an average of three days
Measurements, a technique for eliminating data gaps. Green indicates
Carbon monoxide concentrations of about 100 ppm to
Volume (ppbv); yellow, at about 1

20 ppbv; and dark red at about 160 ppbv. Local
Values ​​can be significantly higher.

A
Pollutant that can travel long distances can leave carbon monoxide in the air
Atmosphere for about a month. The height shown in these pictures is the
Gas has little influence on the air we breathe; Strong winds can carry it however
down, where it can significantly affect air quality. Carbon monoxide
plays a role in both air pollution and climate change.

AIRS, in
In conjunction with the Advanced Microwave Sounding Unit (AMSU), emitted signals are detected
Infrared and microwave radiation from the earth for a three-dimensional appearance
in the case of terrestrial weather and climate. With more than 2,000 different channels
Regions of the atmosphere produce the instruments a global, three-dimensional
Map of the atmospheric temperature and humidity, cloud levels and heights,
Greenhouse gas concentrations and many other atmospheric phenomena.

The AIRS
and AMSU instruments are managed by NASA's Jet Propulsion Laboratory in Pasadena.
California, under contract with NASA. JPL is a division of Caltech.
