Sensing Wildfires in Chile with CATS

This image from the Cloud-Aerosol Transport System (CATS) on the International Space Station (ISS) shows elevated smoke plumes 2 - 4 km above ground level (wispy white areas in the center of the image) from wildfires in central and southern Chile.

CATS in Space

CATS launched in January 2015, and provides measurements of atmospheric aerosols and clouds. Aerosols are tiny solid and liquid particles in the atmosphere, like smoke or ash. Clouds and aerosols play an important role in Earth’s climate system by reflecting and absorbing solar radiation.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
