Recent study for Indonesian astronomical site selection has indicated that regions of East Nusa Tenggara have favorable meteorological conditions, mostly derived from clear sky fraction. As a further study of comparative site analysis, in this paper, we present an evaluation of aerosol distribution over Indonesia as an important parameter of site quality. The long-term availability of meteorological satellite data is obviously useful to obtain the general trends of the corresponding parameter. It is known that the presence of aerosol in the atmosphere can affect astronomical extinction and, therefore, may influence the quality of observational data. The aerosol data analyzed here are from satellite measurements of TOMS-EP, N7, and OMI-AURA of Level 3, from the period of 1978 to mid-2014. We select several locations in Indonesia and compare them to a candidate site in Timor, to obtain the variation of aerosol distribution over the regions of interest. This result is useful to compare with astronomical observations from site testing.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4930666[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
