Analisis Sebaran Suhu Permukaan Laut Di Laut Banda Tahun 2017 – 2019 Menggunakan Data Dari Sensor Amsr-2
Abstract
ABSTRACT
Sea Surface Temperature (SST) measurement is one of the ten key variable in ocean climate change variable. SST can be measure using earth observing satellite (EOS) using thermal infrared or microwave spectrum in instrument such as MODIS or AMSR-2, making way for much complex study regarding rising ocean temperature. Observations using microwave-based sensor, has proven to be useful to measure SST, especially because the sensor capability to penetrate cloud and ignore atmospheric biases. The purpose of this study is to analyze the distribution of SST in Banda Sea using AMSR-2 and OISST data which were processed using IDL software. The result of this study has shown that, the average temperature in Banda Sea is 26oC – 30oC in period of 2017 – 2019, the year 2019 has lower average temperature compare to the year 2017. The yearly temperature also shown that the month of December has the highest average temperature and the lowest temperature happen in the month of august.
Keywords: Sea Surface Temperature, IDL, AMSR-2 Instrument, and Remote Sensing
ABSTRAK
Pengukuran Suhu Permukaan Laut (SST) adalah salah satu dari sepuluh variabel kunci dalam variabel perubahan iklim lautan. SST dapat diukur dengan menggunakan satelit pengamat bumi (EOS) dengan menggunakan spektrum inframerah termal atau gelombang mikro dalam instrumen seperti MODIS atau AMSR-2, sehingga membuka jalan bagi studi yang jauh lebih kompleks terkait dengan kenaikan suhu laut. Pengamatan menggunakan sensor berbasis gelombang mikro, terbukti bermanfaat untuk mengukur SST, terutama karena kemampuan sensornya untuk menembus awan dan mengabaikan bias atmosfer. Tujuan penelitian ini adalah menganalisis sebaran SPL di Laut Banda dengan menggunakan data AMSR-2 dan OISST yang kemudian diolah menggunakan perangkat lunak IDL. Hasil pengolahan data menunjukan bahwa dalam rentang 2017 – 2019, Suhu Permukaan Laut di Laut Banda memiliki rata – rata sebesar 26oC – 30oC dengan tahun 2019, memiliki suhu rata – rata yang lebih rendah, selain dari itu, pola tahunan suhu permukaan di Laut Banda adalah suhu tertinggi terjadi di bulan desember, dan suhu terendah terjadi di bulan agustus.
Kata Kunci: Suhu Permukaan Laut (SPL), IDL, Sensor AMSR-2, dan Penginderaan Jauh
