Pytroll/SatPy

Summary

Installation of the v4.1 SPS toolset of Ernst Lobsiger. For the old v3 versions see here.
Don't mix v3 and v4 scripts!

Some alternative scripts are described here.

Installation original SPS toolset

Install Conda Linux

Note: This is a quick overview. For full description on how/why see v3.0: EMCtools.documents/Satpy_for_EUMETCast_HOWTO_V30.txt.
For the relevant part see here.

Goto: miniconda and download:
Latest Miniconda3 Linux 64-bit
Check download with SHA256-hash:
sha256sum Miniconda3-latest-Linux-x86_64.sh

Now run the instatller to do the actual installation:

sh Miniconda3-latest-Linux-x86_64.sh

Accept the license (you have no choice)
Install Miniconda3 in your home directory (default)
Make the installer initialize Miniconda3 (type "yes")

Add to .bashrc:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('~/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "~/miniconda3/etc/profile.d/conda.sh" ]; then
        . "~/miniconda3/etc/profile.d/conda.sh"
    else
        export PATH="/home/eumetcast/miniconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

Now do:

conda update -n base -c defaults conda

conda config --add channels conda-forge

conda create --name pytroll

Install Conda Windows

Note: This is a quick overview. For full description on how/why see v3.0: EMCtools.documents/Satpy_for_EUMETCast_HOWTO_V30.txt.
For the relevant part see here.

Goto: miniconda and download/run the installer:
Latest Miniconda3 Windows 64-bit

Accept the license (you have no choice)
Install Miniconda3 in your home directory (default)
Make the installer initialize Miniconda3 (type "yes")

In the Windows menu, you should now have an Anaconda Powershell Prompt entry. Start it, and you get a Powershell Prompt window. In this shell do:

conda update -n base -c defaults conda
conda config --add channels conda-forge
conda create --name pytroll

Install satpy (both Linux and Windows)

conda activate pytroll

conda install satpy

conda install pycoast (MUST be version 1.6.1. or later)

conda install pyhdf

conda install hdf5plugin

Installation is now done. To deactivate (go to normal prompt):

conda deactivate

For all actions always go to the Pytroll prompt using command:

conda activate pytroll

Installation of the SPS-environment

Download SPS: SPSdata-bare.xxx and SPStools-bare.xxx
Move SPStools-bare.xxx and SPSdata-bare.xxx to the desired location:

Location of SPSdata-bare.xxx on a disk with enough space to hold all your images and movies
Location of SPStools-bare.xxx may be on another location

These locations have to be defined lateron in the Python scripts! Untar/unzip:

Linux:
- tar -zxf SPSdata-bare.tgz
- tar -zxf SPStools-bare.tgz
Windows: If you have command 'zip':
- unzip SPSdata-bare.zip
- unzip SPStools-bare.zip
Otherwise use Windows browser. Make sure that the subdirectories are SPStools and SPSdata, so without the '-bare' extension.

Last preparations: GEO

Go to SPStools/GEOscripts.

Edit GEOstuff.py:
- Adapt locations toodir and datdir
Edit/adapt the scripts MSG*.py, GOES*.py etc. to your needs for area, composite.
At least make sure to adapt in each script the locations where your Eumetcast-data sits:
- segdir: location
- isbulk: if True, data of all dates are in one location, see segdir
  if False, data is expected in location <segdir>/YY/MM/DD
- decomp: normally False (all files as received by Eumetcast, not decompressed)

Do the same for LEOstuff.py in SPStools/LEOscripts

Usage

All satpy runs should be done in the pytroll environment:

Linux: in cmd-shell, do 'conda activate pytroll'
Windows: use Anaconda Powershell
