  3. Intro. to McIDAS-V • Free • Open source software • Powerful visualization & data analysis tool • Build on SSEC’s VisAD and Unidata’s IDV • “Bridge” software's enable McIDAS-X users to run commands/tasks in McIDAS-V environment

  4. Some features of McIDAS-V • Use of Java and Jython for platform independence. • Access to remote servers through firewall. • General display model supports 2D and 3D displays. • Versatile visualization and data analysis toolkit. • Numerous data formats supported (netCDF, AREA, GINI, EUMETCast LRIT, AVHRR L1b, ASCII etc). • Great support team with an online forum.

  5. Intro. to GOES-R ABI • 16 channel imaging radiometer that covers the visible, near-IR and IR Spectral regions. • Spatial Res. • IR = 2KM • Near-IR = 1KM • 0.64um =0.5 KM • Temporal Res. (flex scan mode, [1hr])‏ • Full disk = 4 • CONUS = 12 • Mesoscale (1000x1000KM) =120 • Spectral Res. • Current GOES = ‘6 Bands’ • GOES-R = 16 Bands.

  6. Visualizing simulated ABI in McIDAS-V • With data from the AWG group, we created CF 1.4 compliant netCDF files for: • Full Disk (2km res.)‏ • CONUS (2km res.)‏ • Mesoscale (1km res.)‏ • Katrina (2km res.)‏ • Used McIDAS-V data explorer to ingest files. • NetCDF files. • Displayed images in McIDAS-V map display. • Full disk, CONUS, Mesoscale, Katrina, Analysis.

  7. Full disk simulationABI band 15 (12.3um) June 26 2008 at 20:00UTC. /media/My_Book/MUG-Presentation/MUG-presentation/fulldisk-b15.gif

  8. CONUS Simulations • Rapidly developing severe convection, June 04/05 2005. • High res. WRF model cooperated with CIMSS forward radiate transfer model. McIDAS-X

  9. CONUS band 02(0.64um) 2005-06-04 21:30UTC • Daytime detection of fog, snow and ice cover • Estimation of solar insulation • Smoke, volcanic ash and hurricane analysis /media/My_Book/MUG-Presentation/MUG-presentation/conus-ir.gif#Slide 10

  10. ABI simulated 1Km res. Mesoscale. /media/My_Book/MUG-Presentation/MUG-presentation/meso-b02.gif

  11. Simulated ABI for Hurricane Katrina /media/My_Book/MUG-Presentation/MUG-presentation/katrina-b04.gif

  12. McIDAS-V data analysis toolkit. • Easily create a simple formula in McIDAS-V to compute (NDVI) on the fly. • Use McIDAS-V for scatter analysis of two fields. • Data transact using McIDAS-V.

  13. Band difference (NDVI)Band03(0.86um) – Band02(0.64um)‏ • Can compute band difference on the fly. • Band 03 (0.86um) - Band 02 (0.64um)‏

  14. Scatter AnalysisBand 03 (0.86um) and Band 02 (0.64um)‏

  15. Scatter Analysis Band 14 (11.2um) and Band 11 (8.5um)‏

  16. Data Transact in McIDAS-V

  17. AIRS DPI in McIDAS-V • Created CF 1.4 Compliant netCDF files for: • CAPE, LI, TPW, PW1, PW2, PW3 • Ingested netCDF files using McIDAS-V data explorer and displayed them in the McIDAS-V map display.

  18. Loop of AIRS DPI in McIDAS-V /media/My_Book/MUG-Presentation/MUG-presentation/AIRS-22-192.gif

  19. Con’s Needs lots of memory for large files or loops. Load time Cannot display 16 bands in one frame. Display labels are hard to manipulate. Summary • Pro’s • Little or no programming skills needed. • Very resourceful Users guide. • Lots of room for new ideas and improvements.
