Q:
Can area emissions
formatted for REMSAD v 6.4 be used as
inputs for REMSAD v 7.02?
A:
You can run
REMSAD v 7.02 with the same area
emissions files used for v 6.4, but
there have been some changes,
particularly to the biogenic
emissions.
Although emissions
files for v 7.02 can include
TOL and XYL in area sources, the new
chemparam file does include a default
aromatic fraction, so inclusion of TOL
and XYL is not required. (Note that it
is necessary to use the new chemparam
file with v 7.02. Attempting to
use an earlier chemparam file will
cause errors and REMSAD will not run.)
The biogenic
emissions for v 7.02 are now supposed
to include the species TERP (monoterpenes)
in addition to ISOP (isoprene).
It is still possible to run REMSAD v
7.02 with old biogenic emissions files
that only have ISOP, but there will
then be no biogenic secondary organic
aerosols (SOA3 and SOA4) and ozone
predictions may be somewhat different.

Q:
What
exactly is the parameter
"mxxx" in parm.cmd? How is
it different from "mxx"?
A:
The
parameter "mxxx" is the
largest allowed value for either the
"x" or "y"
dimension in any of the grids,
including the fine grids. Thus,
it is the largest of mxx, mxy, mxfx,
and mxfy where mxx and mxy are the
maximum x and y dimensions allowed in
the coarse grid and mxfx and mxfy are
the maximum x and y dimensions allowed
in any of the fine grids.
