| Zusammenfassung |
| The submodel PSC of the ECHAM5/MESSy Atmospheric Chemistry model (EMAC) has
been developed to simulate the main types of polar stratospheric clouds
(PSC). The parameterisation of the supercooled ternary solutions (STS,
type 1b PSC) in the submodel is based on Carslaw
et al. (1995b), the
thermodynamic approach to simulate ice particles (type 2 PSC) on
Marti and Mauersberger (1993). For the formation of nitric acid trihydrate
(NAT) particles (type 1a PSC) two different parameterisations exist. The
first is based on an instantaneous thermodynamic approach from
Hanson and Mauersberger (1988), the second is new implemented and
considers the growth of the NAT particles with the aid of
a surface growth factor based on Carslaw et al.
(2002). It is possible to choose
one of this NAT parameterisation in the submodel. This publication explains the background of the
submodel PSC and the use of the submodel with the goal of simulating realistic
PSC in EMAC. |
