Hi Kyoko, I was talking to Lansing a few minutes ago when he mentioned that you were trying to find out what the values for the NEXRAD Level III HHC product represented. Since I knew the answer, Lansing asked me to pass the information along to you... The document you are looking for is: ICD For RPG to CLASS 1 User – Build xx.x These can be found on the NOAA website: http://www.roc.noaa.gov/WSR88D/BuildInfo/Files.aspx The most up to date version is currently 14.0: http://www.roc.noaa.gov/wsr88d/PublicDocs/ICDS/2620001U.pdf Page 3-38 of this document has a table that describes what each level means: Data Level Displayed Code Hydrometeor Classification 0 ND Below Threshold 10 BI Biological 20 GC Anomalous Propagation/Ground Clutter 30 IC Ice Crystals 40 DS Dry Snow 50 WS Wet Snow 60 RA Light and/or Moderate Rain 70 HR Heavy Rain 80 BD Big Drops (rain) 90 GR Graupel 100 HA Hail, possibly with rain 140 UK Unknown Classification 150 RF Range Folded NB: levels 110, 120 and 130 are not (yet) used. I hope that this helps... Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
