Abstract

This is an example of how to run Puff from one wind field type and then restart from defined time interval with different NWP type.

# First run off AVN-GFS
# 24 hrs simulation with 1 hrly outputs

puff -volc=Cleveland -eruptDate "2013 03 19 00:00" -model avn --plumeMin=0 --plumeMax=16000 -saveHours 1 -dtMins 1

# Restart off NAM216
# Note that restart file matches the new start time
# so had 2000 particles from first run and then 2000 particles from second run
# 24 hrs simulation with 1 hrly outputs

puff -volc=Cleveland -eruptDate "2013 03 20 00:00" -model nam216 --plumeMin=0 --plumeMax=16000 -saveHours 1 -dtMins 1 -restartFile=201303200000_ash.cdf

Include is the cdf results along with the png and gif files from ashgmt with the command

ashgmt --movie=Cleveland_multi_winds_used.gif *.cdf
