get_AODN_AltData.sh

#!/bin/bash

# Script to download AODN altimeter data. See the available files at  
# http://thredds.aodn.org.au/thredds/catalog/IMOS/SRS/Surface-Waves/Wave-Wind-Altimetry-DM00/catalog.html
# Altimeters:
# JASON-3 JASON-2 CRYOSAT-2 JASON-1 HY-2 SARAL SENTINEL-3A ENVISAT ERS-1 ERS-2 GEOSAT GFO TOPEX
#
# 3 arguments are read, (1) the altimeter name (exact names, see above), (2) destination path, (3) Hemisphere, N or S
# an example of run is:
# nohup ./get_AODN_AltData.sh TOPEX /media/data/observations/satellite/altimeter/AODN_altm/TOPEX S >> nohup_TOPEX_HS.txt 2>&1 &
