6On 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.

13MODIS 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
14CIMSS 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

The sandwich product was developed by Martin Setvakhttp://www.convection-wg.org/sandwich.php to highlight regions of convection.Here is the sandwich product as produced in McV. This is an enhanced-V pattern… Jason Brunner, KirsBedka (http://cimss.ssec.wisc.edu/snaap/enhanced-v/)Setvak:http://www.convection-wg.org/sandwich.phpBrunner et al.:15
16Advanced 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
17High 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

21Infrared 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.

24Atmospheric 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.[ ]
27Who We Are – SSECScientists - examining the Earth from satellites to gain insight into weather and climateModelers - developing diagnostic and forecast models to explain the weather and climateEngineers - developing new observing tools for spacecraft, aircraft, and ground-based platformsData 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
28What 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 techniquesDeveloped 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 usersPython based user defined computation for scriptingJava-based, open-source, and freely available

31Fundamental CIMSS research: striving to make quality real-time GOES Sounder radiance observations into practical useful information for weather forecastingAtmospheric 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]
32Atmospheric 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.[ ]
