MOVES (Motor Vehicle Emission Simulator) - Frequent Questions
How can I incorporate local data into my MOVES-Nonroad run?
How can I estimate a Nonroad inventory using my own local data?
How can I reduce the time needed to run the Nonroad emission factor post-processing scripts?
What drives seasonal CO emission trends?
Can N2O (nitrous oxide) emissions be estimated in the MOVES Nonroad model?
How do I get carbon dioxide equivalent (CO2e) results for Nonroad equipment?
Why are there no emissions for the early and late hours of the day for certain source types?
When PM emissions are reported by process and “distance travelled” is reported in the “movesactivityoutput” table, why is “distance travelled” not reported by PM process?
Does MOVES incorporate anticipated improvements in VOC emission factors resulting from improved fuel economy?
What does MOVES assume for future year fleet fuel efficiency?
Can MOVES report output in terms of fuel consumption?
Why doesn't my output VMT match my input VMT?
How does MOVES define light duty trucks?
Why in my nonroad results do I have a fuelTypeID not listed in the FuelType table?
How do I get emission factors or inventory totals for Nonroad equipment aggregated by the various categories used by MOVES?
How do I obtain the populations for each of the MOVES source types?
How can I calculate the emission rates for a particular speed using MOVES?
How can I determine the impact of speed on vehicle emissions?
I would like to know how MOVES calculates the CO2 and CO2 equivalent emissions. Could you explain the formula that is used to come up with this output?
