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).
Who We Are – SSEC
• Scientists - examining the Earth from satellites to gain
insight into weather and climate
• Modelers - developing diagnostic and forecast models
to explain the weather and climate
• Engineers - developing new observing tools for
spacecraft, aircraft, and ground-based platforms
• Data Center – real-time satellite imagery from 16
satellites and managing online archive of 1 Petabyte
(back to 1978)
• Software developers - creating tools to visualize and
manipulate data for use by researchers and operational
meteorologists
What Is McIDAS-V?

Powerful data analysis and 3-D visualization tool
McIDAS-V is the fifth generation of McIDAS
“V” stands for 5 (the Roman Numeral V)
The first generation of McIDAS began in 1972

McIDAS-X  VisAD + IDV + HYDRA = McIDAS-V
Viewing data, developing algorithms, validating results
Integration of geophysical data
Ease of reprojection
Remote and local data access
Includes a “bridge” to McIDAS-X, allowing –X users to continue
using legacy code, but to visualize in McIDAS-V
What Is McIDAS-V?
• Uses an extensible framework
- Built a framework on top for adapting new sources of data (format
and type; local or remote), for updating user interface components,
and for creating novel displays and analysis techniques
• Developed in the Java programming language
– object oriented; write once - run anywhere (very portable)
• Persistence mechanism (bundles) for saving and sharing interesting
displays/analysis with other McIDAS-V users
• Python based user defined computation for scripting
• Java-based, open-source, and freely available

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.

Single FOV water-vapor retrieval (color-scale). Slice values are re-sampled on the fly from the
3-D difference field and auto-updated as the slice is dragged in space - demonstrating
interactive direct manipulation, data integration, and python driven data computation.
Bringing observations of clouds together:
MODIS (passive) and CALIPSO (active)
Under development: interrogation of vertical structure of surrounding reference
winds model analysis and/or in-situ obs at location of flagged AMV derived wind.

Fundamental CIMSS research: striving to make quality real-time GOES
Sounder radiance observations into practical useful information for
weather forecasting
Atmospheric
continuity and
evolution are
clearly
evident in
multi-spectral
animation.
Where will clouds be?
Comparison between
observed imagery
(bottom) and forecast
imagery (top) builds
confidence in how
well the CRAS model
is assimilating
retrieved GOES
Sounder cloud and
moisture information.
Where will forecast (GFS) moisture need to
be modified, monitoring trends, to provide
a better forecast for convection (as across
Texas)? Differences between retrieved
GOES Sounder TPW and the GFS forecast
values are plotted over the GOES TPW
Derived Product Imagery (DPI).

Atmospheric soundings from

Below is total precipitable
water (TPW) derived from
the Sounder on GOES-13 at
12 UTC on 21 Jun 2012.
As a cold front moves
across GrtLks and Cen
Plns, dry air fills in
across N Plns as moist
air (previously advected
from the Gulf of Mexico
region) remains over
most of rest of E US.
Smooth GOES
retrievals (profiles) are
similar to near-by
radiosonde profiles.
