ECHAM5/MESSy v2.53.0 model (EMAC) formic acid and formaldehyde (2010-2012)

The dataset includes netcdf files with daily and montly averaged formic acid (HCOOH), formaldehyde (HCHO) and methanediol (HOCH2OH) volume mixing ratio profiles, along with ancillary data (e.g., pressure), simulated by the chemistry-climate model ECHAM5/MESSy v2.53.0 (EMAC) over 2010-2012. The monthly averaged data files also include the carbon monoxide (CO) volume mixing ratio profiles and the yield of CO from methane (CH4) oxidation. The data are available on a T63 horizontal grid, i.e. with a spherical truncation of T63 (corresponding to a quadratic Gaussian grid of approximately 1.9° by 1.9°), with 31 vertical hybrid levels. Three simulations are provided: 1) EMAC(base) is a reference simulation, 2-3) EMAC(dioh) and EMAC(diol) are simulations with explicit cloud chemistry of formaldehyde.

The Modular Earth Submodel System (MESSy) is continuously further developed and applied by a consortium of institutions. The usage of MESSy and access to the source code is licensed to all affiliates of institutions which are members of the MESSy Consortium. Institutions can become a member of the MESSy Consortium by signing the MESSy Memorandum of Understanding. More information can be found on the MESSy Consortium Web-site (http://www.messy-interface.org). The modifications used to produce this dataset have been implemented based on MESSy v2.53.0. The exact source code used to produce the results is archived at the Jülich Supercomputing Centre (JSC) in Jülich and can be made available to members of the MESSy community upon request.
