Ship clouds over the Northern Pacific Ocean •

Today’s Image of the Day from NASA Earth Observatory features distinctive clouds over the Northern Pacific Ocean known as ship tracks.  

When exhaust is emitted by ships, water vapor collects around the tiny particles, or aerosols, and cloud seeds are formed.

Ship clouds typically form around low-lying stratus or cumulus clouds. They also appear brighter and thicker than other clouds because the pollution contained in them scatters sunlight.

This image was captured on August 26th by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.
