Area source vs point source

Post by arl.noaa »

Hello
To determine an area source, I should adjust area with every point so the total area over all points represents the area of the main source. But how is the area considered for each point source in HYSPLIT? Circle or square? In other words what is the best way to determine points and allocate area to each of them in order to have the right total area?

The area is just used in the computation of the emission amount. The shape doesn't matter in 3D particle mode ... all releases are point sources.
