Monitoring wildfire smoke from space • Earth.com

Today’s Image of the Day from NASA Earth Observatory features the Multi-angle Imaging SpectroRadiometer (MISR), which contains nine cameras that can be used to monitor the smoke from wildfires.

As the MISR passes over a smoke plume on the Terra satellite, it captures pictures from nine different angles. This is extremely useful for helping scientists understand more about the nature and the behavior of wildfire smoke.

Ralph Kahn is an atmospheric scientist at NASA’s Goddard Space Flight Center.

“By taking data at all of these angles, we are able to make use of parallax to estimate the height of plumes,” said Kahn. “By looking sideways along multiple paths through smoke and haze in the atmosphere, we also gather important details about how the particles reflect or absorb light, which is key to understanding the amount, size, shape, reflectivity, and other particle properties.”
