A new radiation infrastructure for the Modular Earth Submodel System (MESSy, based on version 2.51)
The Modular Earth Submodel System (MESSy) provides an interface to couple submodels to a base model via a highly flexible data management facility (Jöckel et al., 2010). In the present paper we present the four new radiation related submodels RAD, AEROPT, CLOUDOPT, and ORBIT. The submodel RAD (incl...

| Summary: | The Modular Earth Submodel System (MESSy) provides an interface to couple
submodels to a base model via a highly
flexible data management facility (Jöckel et al., 2010). In the present paper
we present the four new radiation related submodels RAD, AEROPT, CLOUDOPT,
and ORBIT. The submodel RAD (including the shortwave radiation scheme
RAD_FUBRAD) simulates the radiative transfer, the submodel AEROPT calculates
the aerosol optical properties, the submodel CLOUDOPT calculates the cloud
optical properties, and the submodel ORBIT is responsible for Earth orbit
calculations. These submodels are coupled via the standard MESSy
infrastructure and are largely based on the original radiation scheme of the
general circulation model ECHAM5, however, expanded with additional features.
These features comprise, among others, user-friendly and flexibly
controllable (by namelists) online radiative forcing calculations by multiple
diagnostic calls of the radiation routines. With this, it is now possible to
calculate radiative forcing (instantaneous as well as stratosphere adjusted)
of various greenhouse gases simultaneously in only one simulation, as well as
the radiative forcing of cloud perturbations. Examples of online radiative
forcing calculations in the ECHAM/MESSy Atmospheric Chemistry (EMAC) model
are presented. |
