AWIPS users must infer vertical storm structure using 2D representations of radar data.
All Tilts: a series of 2D “horizontal” cross-sectionsBut PPIs are not horizontal – elevation angles are slanted.
AWIPS Vertical Cross-sections (OB7.1)Not easy to useOnly complete during short period at end of volume scanData are remapped to Cartesian spaceNot dynamic (must re-draw to get new cross-section)
Warning decision making demands quick and rapid assessment of the 3D structure of storms.

Integrate National Severe Storms Laboratory (NSSL) Warning Decision Support System – Integrated Information (WDSSII) 3D/4D display technology into AWIPS
Uses Open GL hardware acceleration on standard video graphics cards
FSI will be launched via a D2D extension.
Once extension is loaded, mouse click will open FSI application centered on storm of interest

Improved vertical cross-sectionsDynamic placement and re-position of a cross-section reference line showing real-time updates to the cross-section data. Cross-sections are no longer a one-time requested RPG product, and are instead generated on-the-fly using 8-bit data.
Constant Altitude cross-sections (CAPPIs)8-bit radar data plotted at constant altitude eliminates the need to sample elevation scan data for altitude or reset elevation angle choices in four-panel displays. Cross-section control is also dynamic, showing real-time updates to the cross-section data.
3D visualization8-bit radar data from elevation scans, vertical cross-sections, and CAPPIs are plotted as 2D textures in 3D space. A forecaster can then zoom, pan, pitch, yaw, and fly about the data in 3D.
Virtual VolumesNo volume scan is incomplete. As new elevation scans are updated, they replace the old elevation scans in the virtual volume one-by-one. This means that there are full volumes of data available at all times for cross-sections and data perusal.
Access to entire data inventoryAn “All-Tilts” product only allows the forecaster to peruse a sequential order of elevation scan frames. For a 32 frame limit in VCP12, that only comprises 2 ½ volume scans. The FSI allows the user to access any elevation scan in the radar data inventory RPS list, up to 1 or 2 hours of 8-bit data for all elevation scans.

FSI will be alpha tested on AWIPS OB7.2 in 2007 (tentative):SR: Gulf Coast WFO (TBD; mid-winter)SR: Norman, OK - as part of the National Hazardous Weather Testbed (spring)CR: Omaha, NE (spring, early summer)ER and WR: to be determined (summer)
Similar in concept to WDSS and WDSSII testbedsApplication developer staffing during severe weather operationsFeedback via surveys, etc.
FSI is primary driver for choice of video graphics card (to support 3D visualization) on LX workstation technology refresh, due in Winter 2007.
Delayed FSI testing until new hardware can be delivered to the field.
