Document Number 2620003NCode Identification 0WY55WSR-88D ROC2009Build 12.016 STORM RELATIVE MEAN RADIAL VELOCITY (SRM, SRR)16.1 SS Product Description"This product shall provide mean radial velocity for: (a) a small geographic area centered upon ornear an identified storm of interest with the storm motion removed, or (b) the entire area of radarcoverage (to 230 km) with the average storm motion removed. This product shall be produced uponrequest for any azimuth scan at any elevation angle. The product shall be generated as adisplayable image by removing the radial (velocity component away from the radar antenna)component of storm motion from the mean radial velocity values.The radial component of storm motion shall be computed using the storm motion value computed forthe identified storm by the Storm Cell Tracking Algorithm, the vector average of all currentlyidentified storms or a value input by the user. The value of storm motion used to adjust the meanradial velocity values shall be user selectable at the time of product request, or default to the vectoraverage of all currently identified storms if not selected. Each product shall contain 16 data levelsfor storm-adjusted mean radial velocity. Each product shall include annotations for the productname, radar ID, time and date of scan, elevation angle, storm motion, coordinates of product center,radar position, radar elevation above MSL, and radar operational mode."16.2 Display FormatEach product version is displayable in full- or quarter-screen format (see Appendix B).16.2.1 Data LevelsBoth product versions use 16 data levels. The data level code may vary with operational mode andwith <strong>NEXRAD</strong> (or agency) system adaptation data. One currently identified velocity table is shown.16.2.2 Color Level Code TablesColor Levels16-LevelCodeDisplayknotsRangeknots Code Color0 ND SNRknots (00 E0 FF) light blue2 -40 -40>knots>-50 (00 80 FF) medium blue3 -30 -30>knots>-40 (32 00 96) dark blue4 -22 -22>knots>-30 (00 FB 90) light green5 -10 -10>knots>-22 (00 BB 00) medium green6 -5 -5>knots>-10 (00 8F 00) dark green7 -1 0>knots>-5 (CD C0 9F) light gray8 0 0
