Downloading WOD

You can download the WOD files from the NODC website through an online query (http://www.nodc.noaa.gov/OC5/SELECT/dbsearch/dbsearch.html), you can also download the entire database if you look hard enough for the links (http://www.nodc.noaa.gov/OC5/WOD09/data09geo.html).  I didn't feel like pointing and clicking myself to death so I wrote this script to download the entire thing.  I also added a line in the script to compile a summary database of the CTD and XBT data for use in svp_tool.

#!/bin/bash

count=0

mkdir -p {OSD,MBT,CTD,XBT,PFL,MRB,DRB,APB,UOR,GLD}/OBS
mkdir -p {OSD,MBT,CTD,XBT,PFL,MRB,DRB,APB,UOR,GLD}/STD

echo "Downloading the WOD database"

    for latitude in 0 1 2 3 4 5 6 7 8

        for longitude in 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17

            let count++
            for type in OSD MBT CTD XBT PFL MRB DRB APB UOR GLD
            do 
                # Get the "observed" data
                file=$type\O$quadrant$latitude$longitude.gz
                wget http://data.nodc.noaa.gov/woa/WOD09/GEOGRAPHIC/$type/OBS/$file
                mv $file $type/OBS

                # Get the "standard level" data (observed is filtered and then
                # interpolated to standard depth levels)
                file=$type\S$quadrant$latitude$longitude.gz
                wget http://data.nodc.noaa.gov/woa/WOD09/GEOGRAPHIC/$type/STD/$file
                mv $file $type/STD
            done
