Installation

System setup

The commands with sudo have to be ran from a user account with sudo priviledges, or directly from root, without sudo. Commands that do not start with sudo have to be ran from a normal user account. Example xtuser on CONABIO servers.

Run from an account with sudo priviledges or from root without sudo

# Install generic and spatial libraries
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install libproj-dev libgeos-dev gdal-bin libgdal-dev
sudo apt-get install python-pip git
sudo pip install virtualenv
sudo pip install virtualenvwrapper

Run from the user account from which processing will be done

# As the user from which satmo will be operated (e.g. xtuser)
echo 'source /usr/local/bin/virtualenvwrapper.sh' >> ~/.bashrc
source ~/.bashrc

# Install Version v7.4 of Seadas
wget http://oceandata.sci.gsfc.nasa.gov/ocssw/install_ocssw.py
chmod +x install_ocssw.py
seadas_dir=/data/ocssw
mkdir $seadas_dir
./install_ocssw.py --install-dir=$seadas_dir --git-branch=v7.4 --aqua --seawifs --terra --viirsn
echo "export OCSSWROOT=$seadas_dir" >> ~/.profile
source ~/.profile
echo "source $OCSSWROOT/OCSSW_bash.env" >> ~/.profile

# Create a virtualenv named satmo and install the satmo package in it
mkvirtualenv satmo
pip install -U pip
pip install numpy==1.13.1
pip install git+https://github.com/CONABIO/satmo.git

Further details on installing the satmo python library can be found in the project travis file

Autostart

It may be required to have the near real time mode of the system starting automatically on system startup, hence avoiding having to restart it manually after every system reboot, maintenance, etc.S For that, a @reboot cron task can be created. See the explanations below.

# As xtuser, enter crontab edit mode by running:
crontab -e
# And add the following line to the file
@reboot . ~/.profile; . /data/ocssw/OCSSW_bash.env; /home/xtuser/.virtualenvs/satmo/bin/satmo_nrt.py --day_vars chlor_a nflh sst Kd_490 --night_vars sst --l1a_vars afai fai --north 33 --south 3 --west -122 --east -72 -d /export/isilon/datos2/satmo2_data/ -multi 3 > /home/xtuser/nrt_log.log &

This crontab entry will run the satmo_nrt.py command on system startup, with the defined parameters.
