Prerequisites

The following software must be installed on your system in order to install and use jawf-geotiff-generator:

To see if git is installed and what version your system has, enter:

$ git --version

Check that the CPC Perl5 Library is available via Perl's @INC. For example, enter:

$ echo $PERL5LIB

To see which version of GrADS your system uses by default, enter:

$ grads -blc "quit"

Steps to Install

NOTE: This application was developed and tested in a Linux environment (RHEL 6), and these instructions are intended for installation in a similar environment. If you want to try installing this in a different operating system, you will have to modify the instructions on your own.

Download and set up jawf-geotiff-generator on your system

These instructions assume that the jawf-geotiff-generator app will be installed in $HOME/apps. If you install it in a different directory, modify these instructions accordingly.

  1. Download jawf-geotiff-generator (this creates a directory called jawf-geotiff-generator):

    $ cd $HOME/apps

    $ git clone https://github.com/noaa-nws-cpc/jawf-geotiff-generator.git

  2. Add the environment variable $JAWF_GEOTIFFS to ~/.profile_user or whatever file you use to set up your profile:

    export REALTIME_ONI="${HOME}/apps/realtime-oni"

  3. Set up the application, including initialization of the SST archive with the past 120 days of daily data:

    $ cd $JAWF_GEOTIFFS

    $ make install

Setup cron

Sample basic cron entry:

00 10 * * * $JAWF_GEOTIFFS/drivers/run-jawf-production.csh 1> $JAWF_GEOTIFFS/logs/run-jawf-production.csh 2>&1

Sample CPC operational cron entry:

00 10 * * * /situation/bin/flagrun.pl CPCOPS_RH6 '$JAWF_GEOTIFFS/drivers/run-jawf-production.csh 1> $JAWF_GEOTIFFS/logs/run-jawf-production.txt 2>&1'

Sample CPC operational cron entry with later attempt to get final data using keep-trying, and emailing a logfile to the app owner:

00 10 * * * /situation/bin/flagrun.pl CPCOPS_RH6 'keep-trying -i 60 -t 60 -e app.owner\@email.domain -s \"jawf-geotiff-generator production FAILED - Check attached logfile\" -l $JAWF_GEOTIFFS/logs/run-jawf-production.txt -- $JAWF_GEOTIFFS/drivers/run-jawf-production.csh'
