  1. VIIRS McIDAS-V Casselton, ND Train DerailmentDecember 31, 2013 William Straka III 1

  2. Background • A train derailment occurred about one mile west of Casselton, North Dakota at 20:10 UTC (2:10 PM local time) on 30 December 2013 • 10 cars of a westbound train transporting grain initially derailed, which then caused an eastbound train transporting crude oil to also derail. • A large fire and multiple explosions erupted from the engine and 18 cars of the derailed eastbound train, which were carrying crude oil from the Bakken oil shale field region in northwestern North Dakota. • Explosion and resulting smoke was caught by GOES-E imagery (thermal and visible) • Suomi NPP VIIRS flew over at 09:06 UTC (3:06 AM local) on 31 December

  4. VIIRS DNB, After0906Z, December 29 2013 Casselton Note added light 1 pixel (~1km) W of Casselton Possible smoke/cirrus

  5. VIIRS M13 (3.9mm), After0906Z, December 29 2013 Casselton Note “warm” pixel in same location

  6. VIIRS M15 (11mm), After0906Z, December 29 2013 Casselton cirrus

  7. Summary • Day/Night Band (DNB) imagery seems to indicate a bright spot, which is in the same location as the train derailment. • Thermal (3.9mm) imagery also shows a relatively warm spot in the same location (note, the surrounding region is snow covered, so the remaining fires will stand out). • While there is some cirrus in the region, it is possible that some of the smoke plume may be visible in the DNB imagery (backlit by the surrounding city lights)
