SSEC Satellite Imagery: Then and Now
Jean M. Phillips, LibrarianSpace Science & Engineering CenterUniversity of Wisconsin-MadisonJuly 2006
What will we talk about?
The Father of Satellite Meteorology Applications Technology Satellites (ATS) Spin-Scan camera Images and movies Web sites and books for further study
Father of Satellite Meteorology
Verner E. Suomi Inventor of Spin-Scan Camera which
allowed continuous viewing of weather from space over a large fraction of Earth’s surface
Suomi understood benefits of observing single weather events at frequent intervals
ATS-I Spacecraft: 1966ATS-III Spacecraft: 1967
From: The Applications Technology Satellite Meteorological Data Catalog: Volume I)
Spin-Scan Camera
From: The Applications Technology Satellite Meteorological Data Catalog: Volume
How did it work?
Suomi used the spin of the satellite to scan the earth – 2400 satellite revolutions needed to produce one Earth image
The camera scanned a small strip of the Earth with each rotation, tilting slightly for the next rotation (or line of the picture)
One Earth image created every 20 minutes
Why is it important to know what the weather will do?
18 November 1967 movie
The first full day of good, color pictures from the ATS-III
