We run the AtChem code as a web service, thus making the MCM simulation of atmosphere chemistry phenomena accessible to other members of the EUROCHAMP group.
New in version 1.5:
New in version 1.4:
New in version 1.3:
You can still use the previous version: v.1.4
The core code is written by Chris Martin in Fortran 90 and uses an open-source library CVODE, providing rapid solvers of ODE systems. The Python wrapper, written by Kasia Borońska, takes care of converting the input data, running the simulation on the server and displaying links to zipped output files. You can download a current version of AtChem from https://atchem.leeds.ac.uk/sources.
Using the on-line version is straightforward. User uploads the mechanism file (in FACSIMILE format), initial concentrations file and, optionally, some configuration files, set environment variables and model parameters. It is also possible to enter the job name and a short description. After pressing "submit", the simulation will be run on the server and links to input and output files will be displayed, along with a unique job ID.
