Dual Satellite View Of Lake Michigan

Dual Satellite View Of Lake Michigan

The image below was sent to us by the CIMSS (Cooperative Institute for Meteorological Satellite Studies) group over at UW Madison. CIMSS has a much more detailed story about this image and the two satellites.  It is a dual GOES Visible loop of Lake Michigan on Wednesday, February 4, 2009. Typically, there is only one GOES satellite looking down on us here in Wisconsin. GOES 12 had that job.  However, back on December 14, 2008, the GOES 12 satellite suffered an anomaly and was taken off-line. GOES 13 had been in in-orbit storage since lifting off from earth on May 24, 2006 and subsequently reaching its geosynchronous orbit. When GOES 12 failed, GOES 13 was woken up and brought on-line. GOES 12 is now back which means GOES 13 will likely go back to storage mode next week. Until then, we are benefiting from dual imagery.

In the image below, with GOES 12 on the left and GOES 13 on the right, you can clearly see the lake effect snow band that pounded northern Indiana: Story 1 and Story 2. The other interesting feature is the ice hugging the shoreline of the lake. You can see how it slowly moves around due to the prevailing wind flow.  You can also see the different positions, or perspectives of the satellites.  GOES 12 is looking at us from a more eastern position when compared to GOES 13.   visible satellite image
