SPOTL

This page list the operation procedure of tide forecast from the SPOTL program

To use SPOTL for tide forecast, please follow the procedure below:

1. Define the location in Longitude and Latitude, and Time

2. Create a file called something like doit.oclook.osu.indo and modify the following line based on selected tide model:

#!/bin/sh
#
# this file extracts tidal constants for lat $1 long $2
# and writes the result in a hartid-compatiable file $3
#   e.g.  doit.oclook.osu.indo 11.68 92.77 hc.pblair.osubengal
../bin/oclook o1.osu.indonesia $1 $2 o > tmp
../bin/oclook k1.osu.indonesia $1 $2 o >> tmp
../bin/oclook k2.osu.indonesia $1 $2 o >> tmp
../bin/oclook m2.osu.indonesia $1 $2 o >> tmp
../bin/oclook p1.osu.indonesia $1 $2 o >> tmp
../bin/oclook q1.osu.indonesia $1 $2 o >> tmp
../bin/oclook n2.osu.indonesia $1 $2 o >> tmp
../bin/oclook s2.osu.indonesia $1 $2 o >> tmp
cat tmp | ../bin/harprp o > $3
rm tmp

This file is to define the tide model used for your forecast model. The location will be taken from the other file that we defined later.

3. Create a file called something like doit.oclook.cgp1 and modify the following line based on your location:

#sh doit.oclook.osu.indo  $1    $2      $3
 sh doit.oclook.osu.indo  5.375 095.240 hc08.CGP.ACEH
 sh doit.oclook.osu.indo -1.157 100.374 hc08.CGP.PADG
 sh doit.oclook.osu.indo -5.193 122.938 hc08.CGP.SUL1
 sh doit.oclook.osu.indo -5.512 123.714 hc08.CGP.SUL2
 sh doit.oclook.osu.indo -5.484 123.747 hc08.CGP.SUL3

4. Now you need the third file
