Who We Are
SSEC (Space Science and Engineering
Center) is part of the Graduate School of
the University of Wisconsin-Madison
(UW).
SSEC hosts CIMSS (Cooperative Institute for
Meteorological Satellite Studies),
including a NOAA/NESDIS (National
Oceanic and Atmospheric
Administration /National Environmental
Satellite, Data, and Information Service)
research branch – ASPB (Advanced
Satellite Products Branch).

McIDAS-V is the fifth generation of McIDAS
“V” stands for 5 (the Roman Numeral V)
The first generation of McIDAS began in 1972

On 6 December 1966, the Applications Technology Satellite (ATS-1)
was launched. We have had the benefit of the geostationary
perspective for over 45 years!
ATS-1's spin scan camera
(UW’s Suomi and Parent
1968) provided full disk
visible images of the earth
and its cloud cover every
20 minutes. The spin scan
camera on ATS-1 occurred
because of extraordinary
efforts by Verner Suomi
and Homer Newell, when
the satellite was already
well into its fabrication.

and auto-updated as the slice is dragged in space - demonstrating interactive direct manipulation, data
integration, and python driven data computation.

Infrared electromagnetic spectrum of the atmosphere
Spectral response functions
for the 18 infrared GOES
Sounder bands, separated
into long, mid, and
shortwave sections.
Incoming solar radiation peaks in the visible, near 0.5 um (corresponding to a
radiative temperature of 5780K for the Sun’s surface); outgoing terrestrial radiation
peaks in the infrared, near 11 um (corresponding to an average earth radiative
temperature of 255K). [ from Wein’s Law] Various gaseous constituents effect the
amount of absorption at the different wavelengths.
All spectral bands of the GOES Sounder
( GOES-13 (East) at 15:46 UTC on 23 June 2013 )
Looking at real-time GOES Sounder data…

Atmospheric soundings from
geostationary orbit
Below is total precipitable
water (TPW) derived from the
Sounder on GOES-13 at 12 UTC
on 23Jun 2013.
As a cold front drops
across the N Hi Plains
bringing drier air, the E
and rest of the central US
stay under very moist air
(previously advected from
the Gulf of Mexico region)
as a warm front moves up
across the Great Lakes.
Smooth GOES retrievals
(profiles) are similar to
near-by radiosonde
profiles.
