[Met_help] [rt.rap.ucar.edu #100104] History for MODE-MTD units of speed, distance travelled and duration

  Initial Request
----------------------------------------------------------------

Cheers everyone,

this is no urgent problem, but I would be happy to know for sure.

I am wondering in which units of the MODE-MTD output of speed, distance 
travelled and duration. Are they controlled by grid spacing and output 
time step?

Cheers
Sebastian

Hi Sebastian,

Your guess for the speed and distance units was correct; MTD
determines an
object's velocity by the grid resolution and the time step between
each
input file. Effectively, it's grid unit per time unit.

This link
<https://met.readthedocs.io/en/latest/Users_Guide/mode-td.html#d-
single-attributes>
in the MET User's Guide will provide a little more background on the
subject.
