Visible Satellite Image at NightSeptember 25th, 2013 at 3:07 am by Bill Steffen under Bill's Blog, Weather
On TV and online you can find both visible (daytime) satellite pictures and infrared (nighttime) satellite pictures. Check out this picture visible satellite image taken at 2 AM last Sunday, when the full Harvest Moon was high in the sky (here it is full screen). This is from the Suomi NPP Polar Orbiting satellite. It is light-sensitive enough to take a picture at night in the full moon. Note the cities where there is a lot of non-natural light. You can pick out Grand Rapids, Chicago, Minneapolis – and even smaller towns like Grand Haven, Allegan and Sturgis. You can see fog in the lower Wisconsin and nearby Mississippi River Valleys. You’ve got to see the entire story at the Milwaukee NWS website and see the comparison of nighttime infrared and night/visible pictures. Note how much better you can see where the low clouds are on the visible picture. Don’t I wish I had this clear satellite view every night in real time, especially in winter when the nights are longer and when it’s very difficult to see where the clouds are because the low-cloud and ground temperatures are similar in the cold season. Thanks to the Milwaukee NWS for posting this…interesting.
