Two satellites are better than one

While it might feel more like a fall day, this image is just an example of the water vapor image for a NOAA eye in the sky called GOES. This geostationary satellite is invaluable to monitoring developing weather, especially critical for tropical storm formation.

On Saturday NOAA and NASA successfully launched GOES O. This satellite will be prepared to take over if one of the other GOES fails. Since these satellite travels in sequence with the earths rotation we can animate the imagery.

One GOES monitors the Pacific region and one the Atlantic. There was a time when I worked for NOAA that we did not have a spare ready in place and were required to reposition the east monitoring GOES towards the central part of the northern hemisphere to get a view of the Pacific during hurricance season.

Always nice to have a spare.

I want my summer back.
