View a summary of the updates to CB-IV

The Carbon Bond-IV photochemical mechanism is a widely used and
accepted model of tropospheric chemistry.  A new and updated version
of CB-IV is presented here accompanied by all of the documentation upon
which the changes to the mechanism are based.  CB-IV_99 is better than
the currently used versions of the Carbon Bond mechanisms for several reasons:

- It is fully documented and has been subjected to the USEPA mandated
vindication procedure for regulatory photochemical mechaisms

- It combines the best of the old versions of CB-IV with the currently best-
available information from the literature

- It is developed using a revised smog chamber wall mechanism that uses
the most current knowledge of surface and heterogeneous chemistry

!!!Download CB-IV_99!!!
The new CB-IV mechanism and wall model are available here,
as well as the PKSS and Morpho software packages.

Example plots of CB-IV_99 performance and the complete set of
documentation are available here.
