The August Complex Fire and others this fire season have been sending far-reaching plumes of wildfire smoke into the atmosphere that worsen air quality in California and beyond. Predicting where that smoke will travel and how bad the air will be downwind is a challenge, but Earth-observing satellites can help.

The Afar Triangle: 15 Years of ASTER Imagery

ASTER_first_An_v2Fifteen years ago this month the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor onboard NASA’s Terra satellite began returning images. The first image from ASTER’s thermal infrared (TIR) subsystem was captured on March 3, 2000 of the western edge of the volcanic Afar Triangle in Ethiopia (see image to the right). This image represents not only ASTER’s first thermal image, but also the first high resolution multispectral thermal data collected by a sensor on a satellite. Since this first image 15 years ago, ASTER data has continued to be valuable to geologic and volcanic applications, as well as many other scientific disciplines.
