The large image, which includes a wider area, reveals that the ash is blowing over the Atlantic Ocean west of Ireland. On Iceland, low-level winds pick up ash that had settled on the land. This plume of resuspended ash blows south from the island. The higher-elevation volcanic plume casts a dark shadow on the lower-elevation resuspended ash. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on May 7, 2010. The large image is the highest-resolution version of the image, but the MODIS Rapid Response Team provides the image in additional resolutions.
