Smoke, ash, and aerosols released by the Eyjafjallajökull glacial volcano have caused thousands of commercial airline cancellations since the volcano first erupted on April 14h, 2010. This animation shows the plume as it moves across Europe on April 16th. The data shows the concentration of ash in the atmosphere. The ash mass is calculated by combining multiple spectral channels from the EUMETSAT Meteosat-9 satellite's SEVIRI sensor. The latest image from April 19, 2010 is derived from the NASA Aqua/MODIS satellite sensor. These analyses, developed by NOAA scientists, can distinguish between clouds and other atmospheric aerosols.

The sharing of data between NOAA and its partners in Earth observations is critical in developing advanced products, such as this one, along with the preparation for NOAA's future satellite systems, GOES-R and JPSS.
