The NWS EMC pages detail model changes to 22km runs and extended forecast runs. On NOAAPORT, ETA211 is every 6 hours through 60 hours: 25 010413/1200F000 3000 0 HGHT HLCY 179 010413/1200F006 3000 0 HGHT HLCY 334 010413/1200F012 3000 0 HGHT HLCY 489 010413/1200F018 3000 0 HGHT HLCY 644 010413/1200F024 3000 0 HGHT HLCY 799 010413/1200F030 3000 0 HGHT HLCY 954 010413/1200F036 3000 0 HGHT HLCY 1109 010413/1200F042 3000 0 HGHT HLCY 1264 010413/1200F048 3000 0 HGHT HLCY 1419 010413/1200F054 3000 0 HGHT HLCY 1574 010413/1200F060 3000 0 HGHT HLCY On the ftp servers at NWS, ETA 212 (40km grid) is 3 hrly and has 57 hours: Number of grids in file: 11845 Maximum number of grids in file: 12000 NUM TIME1 TIME2 LEVL1 LEVL2 VCORD PARM 66 010413/1200F000 3000 0 HGHT HLCY 621 010413/1200F003 3000 0 HGHT HLCY 1184 010413/1200F006 3000 0 HGHT HLCY 1749 010413/1200F009 3000 0 HGHT HLCY 2314 010413/1200F012 3000 0 HGHT HLCY 2879 010413/1200F015 3000 0 HGHT HLCY 3442 010413/1200F018 3000 0 HGHT HLCY 4007 010413/1200F021 3000 0 HGHT HLCY 4572 010413/1200F024 3000 0 HGHT HLCY 5137 010413/1200F027 3000 0 HGHT HLCY 5700 010413/1200F030 3000 0 HGHT HLCY 6265 010413/1200F033 3000 0 HGHT HLCY 6830 010413/1200F036 3000 0 HGHT HLCY 7395 010413/1200F039 3000 0 HGHT HLCY 7958 010413/1200F042 3000 0 HGHT HLCY 8523 010413/1200F045 3000 0 HGHT HLCY 9088 010413/1200F048 3000 0 HGHT HLCY 9653 010413/1200F051 3000 0 HGHT HLCY 10216 010413/1200F054 3000 0 HGHT HLCY 10781 010413/1200F057 3000 0 HGHT HLCY 11346 010413/1200F060 3000 0 HGHT HLCY on NOAAPORT, ETA grid 215 (20km) has HLCY through 60 hours on 0/12Z, but all fields only through 48 hours at 6/18Z Number of grids in file: 1353 Maximum number of grids in file: 2000 NUM TIME1 TIME2 LEVL1 LEVL2 VCORD PARM 27 010413/1200F000 3000 0 HGHT HLCY 90 010413/1200F003 3000 0 HGHT HLCY 153 010413/1200F006 3000 0 HGHT HLCY 218 010413/1200F009 3000 0 HGHT HLCY 283 010413/1200F012 3000 0 HGHT HLCY 348 010413/1200F015 3000 0 HGHT HLCY 411 010413/1200F018 3000 0 HGHT HLCY 476 010413/1200F021 3000 0 HGHT HLCY 541 010413/1200F024 3000 0 HGHT HLCY 606 010413/1200F027 3000 0 HGHT HLCY 669 010413/1200F030 3000 0 HGHT HLCY 734 010413/1200F033 3000 0 HGHT HLCY 799 010413/1200F036 3000 0 HGHT HLCY 864 010413/1200F039 3000 0 HGHT HLCY 927 010413/1200F042 3000 0 HGHT HLCY 992 010413/1200F045 3000 0 HGHT HLCY 1057 010413/1200F048 3000 0 HGHT HLCY 1122 010413/1200F051 3000 0 HGHT HLCY 1185 010413/1200F054 3000 0 HGHT HLCY 1250 010413/1200F057 3000 0 HGHT HLCY 1315 010413/1200F060 3000 0 HGHT HLCY > How is the status of NAWIPS 5.6.b coming along?

Maybe in a week or so I'll have the release available barring massive support load like I have had the past 2 months. I put together a web page for gdradr at: http://motherlode.ucar.edu/unidata/images/nids/gdradr.html VAD is not the same type of product as the NIDS stuff. It is a set of drawing commands rather than "data". GEMPAK doesn't support that product. > I was able to save the radar data from EAX from yesterday's tornado in > Warrensburg, MO.
