Welcome to the MOPSMAP website!

The MOPSMAP* package models the optical properties of aerosol mixtures.

The package consists of a data set of pre-calculated optical properties of single particles, a flexible Fortran program to calculate the properties of user-defined particle ensembles, and an intuitive web interface for online calculations. Besides spherical particles, also spheroids and some irregular particle shapes are currently available.

A short overview is given here. Further details of MOPSMAP are discussed in a GMD paper. All input options of the program are described in a user guide.

To start with: Web interface of MOPSMAP (v1.0)

For advanced studies: The Fortran program with the data set can be downloaded here. The data set is required for running the Fortran program. The full download size is around 30 gigabytes.

Sad news: MOPSMAP co-worker Matthias Wiegner died unexpectedly in July 2020.

The OPAC 4.0 package is available at zenodo.org after the original website was shut down.

This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 640458, A-LIFE, a-life.at).

*MOPSMAP is an acronym for 'Modelled optical properties of ensembles of aerosol particles'.
