LIPI – KOREA Collaboration Introduces Innovation on Rainfall Observation Using Dual Polarization Technology

April 3, 2018

Indonesia and Korea encounter similar problems when it comes to dealing with the risk of climate change which also implements in the change of rain pattern. The consequences of heavy rainfall can be the occurrence of erosion, landslides (mainly at slopes and hills) and flood. Conventional method by using rain gauge has disadvantages chiefly when measuring spatial distribution of the rainfall is accurately needed. In addition, conventional rain gauge has limited capability to observe the rainfall due its small size. Spatial distribution of rainfall is important to provide a more accurate forecast of the risk of flood and erosion.

A Korean team consisting of multi institutions (KICT (Korea Institute of Civil Engineering and Building Technology), JCOMS Co. Ltd., SELAB, Kyungpook National University and Chonnam National University) visits Indonesia to have bi-national seminar (Korea and Indonesia) and to test out the performance of EWRG (Electromagnetic Wave Rain Gauge). This device is used for rainfall observation using dual polarization technology. The seminar was carried out at Research Center for Limnology LIPI in the last week of March 2018. The representatives from Korea (Dr. Sanghoon Lim, Dr. Jungho Choi, Prof. Gyuwon Lee, Dr. Chanjoo Lee, Hoon Choi, M.Ed), Dr. Iwan Ridwansyah (RC Limnology LIPI) and Dr. Indra Gustari (BMKG) presented the research development on rainfall observations in Korea and Indonesia, respectively.

For nearly two weeks (the end of March until the beginning of April), the Korean team has been doing performance tests of EWRG at Bukit Paralayang (Paragliding site), Cisarua. This field activity is supported by Research Center for Limnology LIPI which delegates two representatives Dr. Luki Subehi and Miratul Maghfiroh, M.Sc. as field coordinators.

Director of Research Center for Limnology, Dr. Fauzan Ali, cordially welcomes the Korean team and hopes that this activity will lead to a joint research that benefits between two countries. In regard to this, Dr. Won Kim (project Director from KICT) appreciates all individuals and LIPI for its support during the activities. This collaboration is supposed to be carried on in the coming years.
