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? McIDAS – Man computer Interactive Data Access System • 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 Storm cloud temperatures, showing overshooting tops in 2-D from above Satellite composite image overlaid with GFS relative humidity contour cross-section Same overshooting tops, rotated to view from the side
What Is McIDAS-V? 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.

Advanced Display Capability AIRS Level 1B window channel image (grey-scale) and moveable 2-D slice of ECMWF-AIRS 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.

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). [1800 UT 2 Apr 2004]
Atmospheric soundings from geostationary orbit 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. [ http://cimss.ssec.wisc.edu/goes/realtime/eus/begin-eus.html]
