AIRSEA

STATUS: Image lights_green operational (please contact Andrea Pozzer Andrea.Pozzer *at* mpic.de)
INSTITUTION: Max Planck Institute for Chemistry
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.

AIRTRAF

STATUS: Image lights_amber beta-test
INSTITUTION: DLR Institute for Physics of the Atmosphere
TYPE: diagnostic and process (emissions from aircraft)
MAINTAINER: Hiroshi Yamashita
ORIGINAL CODE: Hiroshi Yamashita, Volker Grewe
DESCRIPTION: AirTraf performs global air traffic simulations on long time scales, taking into account effects of local weather conditions on aviation emissions and contrails. Air traffic information comprises Eurocontrol's Base of Aircraft Data (Revision 3.9) and International Civil Aviation Organization engine performance data. Fuel use and emissions (H2O and NOx) are calculated by the total energy model based on the BADA methodology and DLR fuel flow method. Contrails and climate impact based on ATR20 are also calculated by coupling with other submodels. The flight trajectory optimization is performed by a Genetic Algorithm with respect to 9 aircraft routing options (strategies).

CHEMGLUE

STATUS: Image lights_amber beta-test (please contact Rolf Sander rolf.sander *at* mpic.de)
INSTITUTION: Max Planck Institute for Chemistry
TYPE: process (chemistry)
MAINTAINER: Rolf Sander
ORIGINAL CODE: Rolf Sander
DESCRIPTION: Normally, the MESSy submodel MECCA contains one chemical mechanism that is used for all grid boxes of the base model. This ensures a consistent chemistry simulation from the surface to the upper atmosphere. However, in some cases, it may be preferable to allow different mechanisms in different boxes. PolyMECCA provides several, independent chemical MECCA mechanisms. To select an appropriate mechanism at each point in space and time, the MESSy submodel CHEMGLUE has been written. The name of the submodel was chosen because CHEMGLUE also ``glues'' together different chemical mechanisms at the border where a chemical species is included in one mechanism but not in the other.

CHANNEL

STATUS: Image lights_green operational (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 (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 output into data files and the input / output (IO) into / from check-point (restart) files. The implemented IO features comprise
  • a complete control (user interface) via two Fortran95 namelists,
  • a powerful restart facility (check-pointing) for simulation chains,
  • output redirection to create 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.

TYPE: process (representation of atm. species abundances)
MAINTAINER: Sergey Gromov
ORIGINAL CODE: Sergey Gromov
DESCRIPTION: This submodel allows to simulate solar zenith angle (SZA) correlated variations in tracer abundance around a given average value. The initially intended application of this submodel is to better represent (mimic) the diurnal variations in OH (or any short-lived photolysis-correlated tracer), which average daily (or monthly, annually) value is prescribed. The latter is conventionally applied in global chemistry transport models. The calculations involved here approximate the solar declination to derive the (cosine of) SZA and use local solar time to gauge the modulation amplitude around a given baseline.

TYPE: process (photolysis rates)
MAINTAINER: Rolf Sander
ORIGINAL CODE: Jochen Landgraf, Wilford Zdunkowski
DESCRIPTION: JVAL calculates photolysis rate coefficients (``J-values''), i.e. the speed of dissociation of atmospheric molecules in the sunlight. It uses 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 the UV and visible wavelength range, together with pre-calculated effective cross-sections (sometimes temperature and pressure dependent) for tropospheric and stratospheric species. JVAL also includes the auxiliary program JVPP (JVal PreProcessor) which pre-calculates these parameters based on the absorption cross sections and quantum yields of the atmospheric molecules. For the mesosphere, Ly-alpha radiation is also included. Optionally, the UV-C solar heating rates by ozone and oxygen can be calculated.

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.

MAINTAINER: Benedikt Steil
ORIGINAL CODE: Benedikt Steil
DESCRIPTION: The MTSKIP submodel allows to alter the time integration of submodels. Usually a submodel is called every base model time step. With MTSKIP a submodel can be called at odd multiples of base model time step. The integration time step of the submodel(s) subject to skipping is adjusted accordingly. The tendencies of its prognostic variables are kept and added on total tendency every base model time step. MTSKIP does the memory management of the tendencies of the prognostic variables, which are subject to skipping. It deals with the difficulties created by the leapfrog time-integration scheme. Furthermore it contains a massfixer to ensure positive definiteness of tracers. The budgeting of mass potentially created by the mass fixer is also possible. MTSKIP is controlled by only a few parameters, which are descibed in detail in the namelist file. Currently skipping is just enabled for MECCA and JVAL. For skipping of more submodels, please contact maintainer.

TYPE: process (organic aerosol formation and growth)
MAINTAINER: Alexandra Tsimpidi
ORIGINAL CODE: Alexandra Tsimpidi, Vlassis Karydis
DESCRIPTION: ORACLE is a module that comprehensively describes the ORganic Aerosol Composition and Evolution in the atmosphere. It is designed to unify all of the technical features required by ``state-of-the-science'' air quality modules and the latest experimental discoveries that reveal the complex nature of organic aerosol (OA), into a single open-source system that is computationally efficient and flexible. The ORACLE module assumes a wide variety of semivolatile organic products and then separates them into groups of compounds with logarithmically spaced effective saturation concentrations. The model distinguish SVOCs and IVOCs from biomass burning and fuel combustion sources and VOCs from anthropogenic and biogenic sources using surrogate species for each source category and several effective saturation concentrations that can be defined by the user. Gas-phase photochemical reactions that change the volatility of the organics are taken into account and the oxidation products (SOA-sv, SOA-iv, and SOA-v) of each group of precursors (SVOCs, IVOCs, and VOCs) are simulated separately in the module to keep track of their origin.

SPE

STATUS: Image lights_amber beta-test , Image lights_red alpha-test (ionisation effects); (please contact Stefan Versick stefan.versick *at* kit.edu)
INSTITUTION: Max Planck Institute for Chemistry, Karlsruhe Institute of Technology
TYPE: process (solar proton events, parameterized ionisation effects)
MAINTAINER: Stefan Versick
ORIGINAL CODE: Andreas Baumgaertner
DESCRIPTION: The submodel parameterises the effects of ionisation in the atmosphere. NOx and HOx production rates are calculated from ionisation rates, which are computed from GOES proton flux measurements, precalculated by another model (e.g. AIMOS), are parameterized and depend on Kp-Index (only thermosphere) or are coming from the parameterisation of photoionisation. Instead of parameterising NOx and HOx production rates, the module also can be coupled to a simple ion chemistry meccanism and produces ions directly.

TBUDGET

STATUS: Image lights_red alpha-test (please contact Phoebe Graf Phoebe.Graf *at* dlr.de)
INSTITUTION: DLR Institute for Physics of the Atmosphere
TYPE: diagnostic (tagging)
MAINTAINER: Phoebe Graf
ORIGINAL CODE: Phoebe Graf, Patrick Jöckel
DESCRIPTION: The submodel specifies the contribution of different production cycles (e.g. associated with different source gases) to a tracer (family). This is done by defining additional diagnostic tracers with certain production rates. These are specified in namelist entries together with the total tracer and the loss of the total tracer. For a tracer t, a sub-tracer t_i is calculated by d/dt (t_i) = P_i + L*(t_i/t), where L is the destruction rate of t and P_i the production of tracer t_i. A numerical correction (scaling) of t_i to ensure that the sum (over i) of all t_i equals the total tracer (family) t is applied automatically.

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.
