Climate monitoring using satellite

Monitoring the phenomenon of climate change and global warming continue to be developed with various techniques. One of them with remote sensing techniques using satellites.

This effort took Indonesia to Japan to operate a new generation of satellites, the Advanced Land Observing Satellite (ALOS).

Since its launch in Tanegashima, Japan, in January 2006, satellite remote sensory data has been applied in various fields in Indonesia.

"Implementation involving relevant agencies and several universities," said Ruth Dewanti, Head of Public Relations Bureau Institute of Aeronautics and Space Agency (Lapan), on the sidelines of seminar of the Center for Remote Sensing and Ocean Sciences (CReSOS) in Sanur, Bali, which ended , Tuesday (9 / 3).

ALOS is designed for cartography, regional observation area, disaster monitoring, and surveys of natural resources. This new generation satellite has a sensor core, the PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping), AVNIR-2 (Advanced Visible and Near Infrared Radiometer type 2) and PALSAR (Phased Array type L-band Synthetic Aperture Radar).

Application development in Japan, in this case JAXA, in collaboration with the University of Udayana CReSOS established to provide training ALOS satellite data utilization.

Director of Environmental Science Master Program Udayana University, Bali, I Wayan Arthana, said satellite data obtained through the earth station is installed at Udayana University.

The data used to monitor matters relating to global warming, among others, changes in ocean conditions, namely the distribution of chlorophyll and coral reef habitat areas or fishing, and sea level rise.

With ALOS satellite data, the level of abrasion and shoreline changes can be monitored.

In terms of potential fisheries, Alan F Koropitan from the Faculty of Maritime Affairs and Fisheries, Bogor Agricultural University (IPB) argues, global warming causes pelagic fish migration from tropical to subtropical regions. This is based on fish migration modeling developed Namuro Japan.

Norway regions expected to experience a surplus of fish due to this global phenomenon. As Indonesia is expected to have reduced the fish population.

Jonson Lumban Gaol, a lecturer in the Department of Marine Sciences and Technology, Bogor Agricultural University, said research by Modis satellite in Bali Strait showed an increase in fish populations lemuru as El Nino, from the original 20,000 tons to 60,000 tons per year.
