Chemistry
Includes the Carbon Bond 05 (CB05) mechanism with the
associated EBI solver. This mechanism includes explicit
gas-phase reactions for N2O5 and H2O. CB05 includes
compatibility with a mercury mechanism.
Aerosols
Updated to version 1.7 of the ISORROPIA thermodynamics
model.
HAPs
Increased number of supported Hazardous Air Pollutants
including several new toxic metals and diesel components
in PM.
PBL
The ACM2 algorithm combines local and non-local closure
schemes.
Source Apportionment
Carbon apportionment and sulfate tracking are supported
for the CB05 mechanism.
Other
The addition of a CGRID restart file for initializing
simulations permits flexible configurations of output
concentration files; this update allows defining subsets
of species and layers to be written to the CONC file. |

Beta version of CMAQ v4.6 Operational Guidance Document (OGD) Now Available
The first ever Operational
Guidance Document for CMAQ is now available in HTML and PDF formats. Changes are still being made daily to this document, so please consider it as a beta version. We welcome any feedback you have about the CMAQ OGD. Please direct feedback to cmas@unc.edu.
MCIPv3.3 (August, 2007)
There were several changes to MCIP in this release including enhancements to the dry deposition routine, bug fixes for processing both MM5 and WRF data, the removal of legacy codes in the MCIP code archive, and other updates to the MCIP science and documentation. See the Release Notes for a complete description of this release.
CMAQ Training in Sofia, Bulgaria
CMAS trainers traveled to Sofia, Bulgaria in August
2006 to teach CMAQ to modelers from government and university
groups around Europe. Sponsored by the ACCENT
initiative, the special workshop was attended by over
30 scientists and included tutorials on SMOKE
and WRF in addition
to CMAQ. Email
us to learn more about CMAS on-site CMAQ training.
