Installation instructions

Getting the files and installing them

First you need to get the files from github:

cd /path/to/my/source/directory/
git clone git://

You can also retreive a tarball from there if you prefer, then run:

tar zxvf tarball.tar.gz

Then you need to install mpop on you computer:

cd mpop
python install [--prefix=/my/custom/installation/directory]

You can also install it in develop mode to make it easier to hack:

python develop [--prefix=/my/custom/installation/directory]


Environment variables

Environment variables which are needed for mpop are the PYTHONPATH of course, and the PPP_CONFIG_DIR, which is the directory where the configuration files are to be found. If the latter is not defined, the etc directory of the mpop installation is used.

Input data directories

The input data directories are setup in the satellite configuration files, which can be found in the PPP_CONFIG_DIR directory (some template files are provided with mpop in the etc directory):

format = 'xrit/MSG'


The different levels indicate different steps of the reading. The level2 section gives at least the plugin to read the data with. In some cases, the data is first read from another level, as is this case with HRIT/LRIT data when we use mipp: there we use the level1 section.

The data location is generally dealt in to parts: the directory and the filename. There can also be additional filenames depending on the reader plugin: here, mipp needs also the filename for prologue and epilogue files.

Note that the section starts with the name of the instrument. This is important in the case where several instruments are available for the same satellite. Note also that the filename can contain wildcards (* and ?) and optional values (here channel, segment, and time markers). It is up to the input plugin to handle these constructs if needed.
