AIRSEA

STATUS: Image lights_red alpha-test (please contact pozzer@mpch-mainz.mpg.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 monodirectional 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.

HETCHEM

STATUS: Image lights_red alpha-test (please contact steil@mpch-mainz.mpg.de)
INSTITUTION: Max Planck Institute for Chemistry
TYPE: process (reaction rates on stratospheric and tropospheric aerosol)
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: Max Planck Institute for Chemistry
TYPE: process (Stratospheric Water Vapor)
MAINTAINER: Christoph Brühl
ORIGINAL CODE: Christoph Brühl, Patrick Jöckel
DESCRIPTION: The H2O submodel defines H2O as a tracer, provides its initialization in stratosphere and mesosphere from satellite data, and controls the consistent feedback with specific humidity of the base model. This submodel further accounts for the water vapor source of methane oxydation in the stratosphere (and mesosphere), either by using the water vapor tendency of a chemistry submodel (e.g., MECCA), or by using a satellite climatology (UARS/HALOE) of methane together with monthly climatological conversion rates from a MAECHAM4/CHEM simulation.

TYPE: process (Photolysis rates)
MAINTAINER: Rolf Sander
ORIGINAL CODE: Jochen Landgraf, Christoph Brühl, Wilford Zdunkowski
DESCRIPTION: This submodel is for fast online calculation of J-values (photolysis rate coefficients) 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 precalculated 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. This submodule has been derived from a preliminary version of the PHOTO submodel.
