WSR-88D Radar Coded Message (RCM) Display Software version 1.8 is now available on the TAPR FTP site (ftp.tapr.org). --------------------------------------------------------------------- You can find the program with complete nexrad map data in ftp://ftp.tapr.org/tapr/software_lib/weather/ A Web page is under development and should be announced shortly. In addition a pdf file covering how Texas and Oklahoma have been using this system via packet radio is available in the same directory. This paper was presented at the 1995 Digital Communications Conference.

The WSR-88D Radar Coded Message Display Software was designed to decode and graphically display the contents of the RCM message for any WSR-88D radar (or nexrad). Once the RCM software is installed, reflectivity data, storm information, and wind data within the RCM can be extracted and graphically displayed. The reflectivity data, when color contoured and animated by this software, offers an excellent radar display and pinpoints areas of developing storms. Storm movement and maximum tops are also superimposed on the reflectivity data. In addition, an interactive hodograph is constructed using the wind data in the RCM. Storm relative helicity values are automatically computed for a storm moving 30 degrees to the right and 75 percent of the mean winds from the surface to 25000 feet MSL. Storm relative helicity values can also be computed using individual storm movements as given within the RCM. This version offers the following additional features: 1) Handles binary and text formatted RCMs. Text formatted RCMs are necessary for transmission through Ham Packet Radio. See Appendix 1 for further details on the text formatted RCMs. 2) Handles 9 and 6-letter RCM file IDs. (Refer to installation instructions for the handling of 6-letter file IDs.) 3) County and state maps for the 48 contiguous states. 4) Looping capabilities. 5) Ground-clutter suppression capabilities. ------------------------------------------------------------------------ Tucson Amateur Packet Radio 8987-309 E Tanque Verde Rd #337 * Tucson, Az * 85749-9399 * 817-383-0000 ------------------------------------------------------------------------ e-mail: TAPR@TAPR.ORG ftp: ftp.tapr.org web: http://www.tapr.org/tapr ------------------------------------------------------------------------
