AEROPT

STATUS: Image lights_amber beta-test (please contact Holger Tost tosth *at* uni-mainz.de)
INSTITUTION: University Mainz
TYPE: diagnostic (aerosol optical properties)
MAINTAINER: Holger Tost
ORIGINAL CODE: Holger Tost, A. Lauer
DESCRIPTION: The AEROPT submodel calculates the AERosol OPTical properties (optical thickness, single scattering albedo, asymmetry factor), which can be coupled (later) to the radiation scheme. The calculations are based on precalculated lookup-tables from Mie calculations with the LIBRADTRAN and are mapped onto the ECHAM5 radiation bands.

AIRSEA

STATUS: Image lights_amber beta-test (please contact Andrea Pozzer pozzer *at* cyi.ac.cy)
INSTITUTION: Max Planck Institute for Chemistry, now Cyprus Institute
TYPE: process (emission/deposition over oceans)
MAINTAINER: Andrea Pozzer
ORIGINAL CODE:  
DESCRIPTION: This submodel calculates the deposition and emission over the ocean, using a two layer model. It is important for correcting the global budget of some organic tracers like methanol and acetone. Unlike other emission-deposition submodels, which are related to mono-directional processes, the AIRSEA is bi-directional, i.e. calculates emission or deposition of a tracer depending on its concentration in air and in the ocean surface water.

CHANNEL

STATUS: Image lights_amber beta-test (please contact Patrick Jöckel Patrick.Joeckel *at* dlr.de)
INSTITUTION: Max Planck Institute for Chemistry, now DLR Institute for Physics of the Atmosphere
TYPE: generic submodel: memory and meta-data management and data export
MAINTAINER: Patrick Jöckel
ORIGINAL CODE: Patrick Jöckel
DESCRIPTION: The generic submodel CHANNEL provides a powerful application programming interface (API) to handle such data for the flexible and efficient data exchange/ data sharing between different processes (submodels). It is written in Fortran95 (ISO/IEC-1539-1) following an object-oriented approach to the extent possible. The basic entities, implemented as Fortran95 structures, of CHANNEL are
  • attributes, representing time independent, scalar characteristics, e.g., the measuring unit,
  • dimension variables, representing specific coordinate axes, e.g., the latitude in degrees north, the zonal wave number, the trajectory number,
  • dimensions, representing the basic geometry in one dimension, e.g., the number of latitude points, the number of trajectories,
  • representations, describing multidimensional geometric structures (based on dimensions), e.g., Eulerian (or gridpoint), spectral, Lagrangian,
  • channel objects, representing data fields including their meta information (attributes) and their underlying geometric structure (representation), e.g., the 3-D vorticity in spectral representation, the ozone mixing ratio in Eulerian representation, the pressure altitude of trajectories in Lagrangian representation,
  • channels, representing sets of ``related'' channel objects with additional meta information. The ``relation'' can be, for instance, the simple fact that the channel objects are defined by the same submodel.
CHANNEL further serves the input/output (IO) of data from/into files. The implemented IO features comprise
  • a complete control (user interface) via two Fortran95 namelists,
  • a powerful restart facility for simulation chains,
  • output redirection for tailor-made output files,
  • a flexible choice of the output file format, of the output method, of the output precision, of the output frequency, and
  • the capability to conduct basic statistical analyses w.r.t. time on-line, i.e., to output in addition (or alternative) to the instantaneous data (i.e., at a specific model time step) the average, standard deviation, minimum, maximum, event counts, and event averages for the output time interval.

MAINTAINER: Benedikt Steil
ORIGINAL CODE: Ken Carslaw, Stefanie Meilinger, Joachim Buchholz, Benedikt Steil, Swen Metzger
DESCRIPTION: The Module HETCHEM calculates heterogeneous reaction rates on stratospheric (NAT, ICE, super-cooled ternary solutions (STS)) and tropospheric (sulfate) aerosols. It can easily be coupled by namelist to aerosol modules, which then provide the aerosol parameters. Climatologies of stratospheric H2SO4 mixing ratios (1960-1999) and tropospheric sulfate aerosol surface (1990) are provided, so that HETCHEM can be used in a minimal configuration to just obtain reactions on sulfate aerosol (e.g. N2O5 + H2O -> 2 HNO3). The reaction rates in the polar stratosphere are similar to the rates calculated by the PSC submodel.

INSTITUTION: Free University Berlin
TYPE: process (mixed layer ocean)
MAINTAINER: Markus Kunze
ORIGINAL CODE: Erich Roeckner
DESCRIPTION: The submodel MLOCEAN calculates the sea surface temperature, ice thickness and ice temperature of ocean gridpoints. It assumes the mixed layer depth of the upper ocean to be constant (default 50 m, changeable via namelist). The temperature of the mixed layer is calculated from the net surface heat flux and a flux correction, that accounts for the horizontal and vertical heat transport. The net surface heat flux is calculated from the sensible and latent heat flux, and the net solar and thermal radiation at the surface. The monthly resolved climatological flux correction has to be provided as input. There are two possibilities to provide a flux correction. The first one is to provide the climatology of the net surface heat flux, which then is used together with the climatological sea surface temperatures to get the final flux correction. The second one is to calculate the final flux correction off-line.

STATUS: Image lights_amber beta-test (please contact Christoph Brühl Christoph.Bruehl *at* mpic.de)
INSTITUTION: Max Planck Institute for Chemistry
TYPE: process (Photolysis rates)
MAINTAINER: Christoph Brühl
ORIGINAL CODE: Jochen Landgraf, Christoph Brühl, Wilford Zdunkowski
DESCRIPTION: The Photolysis submodel is for fast online calculation of photolysis rates using cloud water content and cloudiness calculated by the base model and/or climatological ozone and climatological aerosol. A delta-twostream-method is used for 8 spectral intervals in UV and visible together with pre-calculated effective cross-sections (sometimes temperature and pressure dependent) for more than 50 tropospheric and stratospheric species. If used for the mesosphere, also Ly-alpha radiation is included. Only the photolysis rates for species present are calculated. Optionally, the UV-C solar heating rates by ozone and oxygen are calculated. See also JVAL for other representations / interfaces.

STATUS: Image lights_amber beta-test (please contact Patrick Jöckel Patrick.Joeckel *at* dlr.de)

TYPE: diagnostic
MAINTAINER: Patrick Jöckel
ORIGINAL CODE: Patrick Jöckel
DESCRIPTION: VISO (Vertically layered iso-surfaces and maps) serves two purposes. First, it is used to diagnose vertically layered, 2-D isosurfaces in 3-D scalar fields in Eulerian (grid-point) representation. The search algorithm determines in every vertical column of the field the level index of the box with the specified value and, by linear interpolation, the fraction of the vertical box length below the specified value. The second application of VISO is for mapping 3-D scalar fields in Eulerian (grid-point) representation on surfaces defined by a level index (and optionally by a fraction of the box), as for instance an iso-surface defined by the same submodel.
