KAJIAN PERBANDINGAN MODEL WRF-CHEM DENGAN PENGINDERAAN JAUH UNTUK IDENTIFIKASI ARAH DAN DISTRIBUSI ABU VULKANIK GUNUNG MERAPI PADA KASUS ERUPSI 3 MARET 2020

The aerosol properties of volcanic ash can cause aircraft engine failure. method is used to predict the distribution WRF-Chem model, which a numerical weather forecasting model that added elements chemistry parameters. This study aims examine comparison direction and remote sensing eruption Mount Merapi on March 3, 2020. results show there are differences in terms bin 5-6 classification compared Himawari-8 satellite observation, however. for bins 1-4 7-9, it shows suitability moving northeast towards coast East Java. While based concentration each size according height layers atmosphere general significant difference between observations from Radar Yogyakarta.
