Operational trajectory calculations have ended on 07-26-2013. I am happy to support
you with additional calculations to investigate specific questions! Just let me know.
Choose a release point:
All simulations done using FLEXPART 9.0,
driven by 3 hourly NCEP GFS wind fields
(analyses and +03 hrs forecast interlaced for past periods) on a 0.5 deg lat-lon grid.
10000 particles released for the first 3 hours at each release point between 0 and 100 m AGL (unless noted otherwise in release name),
and followed back in time for 72 hours on a 0.1 deg lat-lon grid.
Resulting footprints (airmass between 0 and 100 m AGL),
are then convolved with emission inventories (0.5 deg) to create loading plots:
anthro: MACCcity anthropogenic NO emissions isoprene/terpenes: MEGAN BVOC emissions as calculated online in a MOZART simulation with realistic meteorology fire: FINN CO emissions from fires, data from day before stacks_so2: NEI SO2 stack emissions (all point sources). We use the 100 - 500m AGL footprint for convolution to account for the fact that stacks emit aloft, not at the surface. mercury: NEI mercury emissions (courtesy of A. Giang, MIT). We use the 100 - 500m AGL footprint for convolution to account for the fact that stacks emit aloft, not at the surface.
All of them are passive air tracers: no chemistry, no (wet/dry) deposition. However, we consider a 2 day e-folding lifetime in emissions (except for mercury).
