MET File to use

Post by gmcurcio » June 21st, 2019, 1:52 pm

I noticed when using the trajectory tool for Archived runs, that the Hybrid Sigma pressure NAM works best. It certainly shows the trajectories at low initiation points. HRRR has the finest resolution but its trajectories were at 100+m when a 2 m trajectory was requested on the input page.

If I am interested in surface trajectories at 6 feet off the ground, what MET file would be best to use. This is to track wildfire smoke movement at the surface. It is at this level that would effect humans & drivers on roadways. Anything that is higher is not of concern in this specific situation I am trying to evaluate. Use of other MET Files have trajectories that jump immediately to a 100+m height while Hybrid Sigma starts at the surface level, the level on the input page and then downstream may go to a higher height.

Any thoughts anyone? Thanks
