What's
new about version 8.03?
Over
the past several years, new features
have been incrementally incorporated
into REMSAD through several versions
of the model. The current version,
8.03, includes all of the features
listed below:
V 7.10:
-Expanded to 17 congeners of
dioxin
-Added nitrogen tagging
-Added sulfur tagging
-Updated temperature dependence
for SOA partitioning
-Revised treatment of wet
surfaces in dry deposition
-Removed certain ammonia
specific treatments in dry deposition
V
7.11:
-Added species VOCB to account
for products of ISOP and TERP
reactions separately from
emitted VOC.
V
7.12:
-Added capability to save deposition broken out by land
use type
-Added re-emission treatment
for mercury
-Revised time stepping
procedure in mercury chemistry
V
8.00:
-Implemented CB-V chemical
mechanism as an optional alternative
to microCB
-Updated mercury chemistry
rates based on recent literature,
including addition
of gas phase reaction of
elemental mercury with OH radical
-Revised fine grid calls to
cloud mixing and wetdep routines to
use coarse grid
values directly rather than
interpolated values.
V
8.01:
-Revised cloud mixing routine
to improve mass consistency
V
8.02:
-Added tagging capability for
dioxin species
-Added mechanism for lead with
tagging capability
V
8.03:
-Revised vertical transport
routine to improve mass consistency
Specific questions
about either of these issues can be
directed to Tom Myers.
