Envisat
overview

|
Envisat captures the birth of a giant iceberg that has
broken off from the Pine Island Glacier in West Antarctica.
Spanning 34 km in length by 20 km in width, the new iceberg
covers an area nearly half the size of Greater London. This
animation is comprised of images acquired between September
2006 and October 2007 by the Advanced Synthetic Aperture Radar
(ASAR) instrument aboard ESA’s Envisat satellite. The area
covered in the images is approximately 230 by 250 km.

This Envisat's MERIS image, acquired on 22 October 2007,
shows desert winds blowing smoke from wildfires in Southern
California. Sand is visible being blown from Mexico’s Baja
California Peninsula over the Gulf of California to the east
and the Pacific Ocean to the west.

Envisat 's Advanced Along Track Scanning Radiometer
(AATSR) instrument, which measures global sea surface
temperature (SST) to an accuracy of 0.2º C, dramatically
illustrates the complexity of the thermal currents at play in
the Southern Mediterranean off the coast of Northern Libya.
The brightest pale blue colour represents the warmest
temperatures of approximately 25º C, while the darkest blue
colour represents cooler temperatures of around 21º C. Image
acquired on 18 September 2007.

The first animation ever produced showing the global
distribution of methane, the second most important greenhouse
gas. Dr. Michael Buchwitz and Oliver Schneising from the
Institute of Environmental Physics (IUP) at the University of
Bremen in Germany produced the animation using Envisat
SCIAMACHY observations from 2003 to 2005.
