The Trajectory files show predicted air mass paths as calculated using the NASA GSFC trajectory model (Schoeberl and Sparling, 1995) at three levels: 500, 1500, and 2500 m initial trajectory altitude. The 7-day back trajectories are run starting one day in the future from a uniform grid centered on Houston using 6-hourly 1X1 NCEP data, in forecast mode for future hours and in analysis mode for hours in the past.

Trajectory Data
Study Period 11 April - 31 May 2009

Note that trajectories in the boundary layer need to be interpreted with some caution and represent only possible air parcel paths.

 

Start Date
7-days back from Houston, Texas (forecast/analysis mode)
