diphon Posted November 14, 2013 Share Posted November 14, 2013 Any ideas what this long radar return could be? It occured in clear air yesterday evening, no clouds or precip . I called the NWS office in Portland Maine and their best guess was chaff. But I have a hard time imagining a plane coming out of Canada dumping chaff for 340 miles on it's way out over the ocean off cape cod. Based on the winds aloft the return was moving with the wind below 16,000' or above 42,000' Link to Loop: http://weather.rap.ucar.edu/radar/displayRad.php?icao=KGYX∏=n0r&bkgr=black&endDate=20131114&endTime=1&duration=8 Link to comment Share on other sites More sharing options...
wxmeddler Posted November 15, 2013 Share Posted November 15, 2013 Chaff is my best guess. I would like to see dual-pol data on it but it's def. something coming from a plane. It could also be fuel dumping, if there was an in flight emergency from a flight to europe, it may dump fuel over the ocean before landing as it can't land near fully loaded.

diphon Posted November 15, 2013 Author Share Posted November 15, 2013 I considered Fuel dumping since there's a tanker base near there, I figured fuel would evaporate faster than that, but I've never seen it on radar. The person I spoke with mentioned that it had a very low correlation coefficient and wasn't a meteorological return. Link to comment Share on other sites More sharing options...
diphon Posted November 15, 2013 Author Share Posted November 15, 2013 I pulled the nexrad level II data and the CC is mostly below .75-.5 and the leading of the trail is about 23,000'. The 3D model of looks pretty neat. Link to comment Share on other sites More sharing options...
