3 What Is McIDAS-V? McIDAS – Man computer Interactive Data Access System
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 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

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.

13 MODIS data - define a transect to display radiance measurements
Can drag transect across image to view the data interactively. This would be a good tool to use with a product. Validation tool. Convection case study: 19 June 2007

14 CIMSS Cloud Top Pressure
Here a window channel image is displayed with a derived cloud top pressure on top. The data probe is used to compare the product with the source data. 14

15 Brunner et al.:
Thunderstorm features: over-shooting top and enhanced-V (thermal couplet) Trying to reproduce a product that is traditional done using a photoshop merge. The sandwich product was developed by Martin Setvakhttp:// to highlight regions of convection. Here is the sandwich product as produced in McV. This is an enhanced-V pattern… Jason Brunner, KirsBedka ( Setvak: Brunner et al.: 15

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. 16

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 . A 3-D “cloud product” – the UW CAVP (Cloud Amount Vertical Profile) - orbit overlayed on topography. CAVP is derived from AIRS data. See work by E. Garms et al. 17

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… Look at all spectral bands Look at a Sounder product [This workshop PowerPoint is available at --

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. [ ]

28 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

31 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]

32 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. [ ]
