Infrared weather satellite image from this morning, showing cirrus clouds near Petermann Glacier and the compact low-pressure system in Melville Bay, with its associated low clouds covering the ice sheet inland.  This image is from the NOAA-15 polar orbiter, and note that portions of the image are garbled.  This is an ongoing problem with this particular weather satellite, and the resulting poor imagery has occasionally hampered our flight decision-making process.
