Surface Temperature Contours Maps

Contour maps of each port region are also hosted on the Great Lakes CoastWatch node and are in near-real time when the satellite passes over the Great Lakes (up to 18 images a day from different satellites).  Currently, the Great Lakes contour maps are using satellite surface temperature images that are derived from the AVHRR sensors on the satellites MetOp B/C and VIIRS sensors on the satellites NOAA20/NPP. The MetOP B/C over the Great Lakes region in the 01-03 AM and 02-05 PM time period. The NOAA20/NPP over the Great Lakes region in the 06-10AM and 05-08 PM time period.
