MTT Ember Outputs

There are two MTT outputs with ember information. These are not necessarily spot fire locations.

When an ember lands on a node the landing time is compared to the current arrival time of the node, the lower time then becomes the arrival time of the node. Any node can have it's arrival time replaced with a lower one regardless if the lower time is the result of another ember of surface fire spread.

Ember Landing Locations

This is a point shapefile of the live ember landing locations for the MTT run.

Ember List

This is a Comma Separated Value (.CSV) file containing more information about the live embers from the MTT run.

Ember list as displayed in Notepad.

The fields are,

Keyword

Description

LaunchX

X coordinate of the live ember launch

LaunchY

Y coordinate of the live ember launch

LandX

X coordinate of the live ember landing

LandY

Y coordinate of the live ember landing

LaunchTime

simulation time when the live ember was lofted from a torching tree

LandTime

simulation time when the live ember landed, plus any spotting delay

Distance(m)

distance the ember traveled in meters

Distance(ft)

distance the ember traveled in feet

Unlike Farsite's Spot Fire List MTT LandTime and LaunchTime  are the same unless Spotting Delay (mins) is greater than zero.
