BACKGROUND

This web page provides near real-time imagery for selected regions. Overlays include the following:

- Effective radius of cloud top hydrometeors. Courtesy of Dan Lindsey, Louie Grasso, Don Hillger (NESDIS/RAMMB and CIRA/Colorado State University):
      Color scale: green, dark to light (cloud water, size range approximately 2-30 microns)
                          blue-yellow-red (ice particles, small to large)
                          transparent to background image (effective radius could not be computed, no cloud or mixed phase clouds)

- Probability of overshooting tops (enhanced convective tops) from visible imagery. Courtesy of V. Lakshmanan (CIMMS/University of Oklahoma)

- IR (GOES window channel brightness temperature < -30 C)

- Radar (Hybrid Scan Reflectivity) from the NOAA/NSSL NMQ system

- 300mb divergence from GOES Mesoscale Water Vapor Wind analysis

- Couplet Magnitude (temperature difference between overshooting top and nearby cloud-top warm spot).  Courtesy of CIMSS Satellite-based Nowcasting and Aviation Application Program (SNAAP).


  Flash-based applications used for interactive animations were developed by Tom Whittaker of the Space Science and Engineering Center (SSEC), University of Wisconsin-Madison.
