  2. 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).

  3. 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

  4. 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

  6. 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.

History of McIDAS-V • 2006 - Investigations of a “new approach” to data analysis and visualization • 2007 – Collaboration with Unidata to advance VisAD and IDV as the basis of McIDAS-V • 2008 – McIDAS-V becomes an “alpha” • 2009 – January – beta 1 • 2010 – January – beta 5 • 2010 – September – V1.0 • 2012 – May – V1.2 (scripting capability demonstrated and promoted) • 2013 – June – latest version is V1.3

  13. MODIS data - define a transect to display radiance measurements Convection case study:19 June 2007

  14. CIMSS Cloud Top Pressure

  15. Thunderstorm features: over-shooting top and enhanced-V (thermal couplet) Setvak:http://www.convection-wg.org/sandwich.php Brunner et al.:http://cimss.ssec.wisc.edu/snaap/enhanced-v

  16. 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.

  17. High spectral data from AIRS (onboard the Aqua satellite) is used to generate the UW Cloud Amount Vertical Profile (CAVP), shown as a “3-D” cloud in McIDAS-V .

  18. Bringing observations of clouds together:MODIS (passive) and CALIPSO (active)

  21. 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.

  22. All spectral bands of the GOES Sounder ( GOES-13 (East) at 15:46 UTC on 23 June 2013 )

  23. Looking at real-time GOES Sounder data… cimss.ssec.wisc.edu/goes/rt/exp-work.php • Look at all spectral bands • Look at a Sounder product [This workshop PowerPoint is available at -- http://cimss.ssec.wisc.edu/~garyw/sum-wrkshp/2013/.]

  24. 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. [ http://cimss.ssec.wisc.edu/goes/realtime/eus/begin-eus.html]
