Monitoring built-up areas in the previous year and possible predictions for the following year are important in planning regional development and controlling the expansion of built-up areas. This study detects changes in the built-up area (2018–2022). It predicts the future (2026) using Landsat satellite imagery in the Sleman Regency, Yogyakarta Sp...

Drought is a regional phenomenon that is naturally affected by climate conditions. Climate change, which changes the pattern of rainfall and temperature, is very influential on the drought conditions in an area. Yogyakarta Province is one of the regions in the south of Indonesia with a distinctive regional character. By using rainfall data and the...

The relocation of the Indonesian capital from Jakarta to Ibu Kota Nusantara (IKN) East Kalimantan IKN will affect several sectors. The change in land use from vegetated to developed land will lead to local climate changes, including the emergence of the urban heat island (UHI) phenomenon, which is reflected in a higher land surface temperature (LST...

Monitoring of near-surface aerosol is important for both public health issues and radiation budget studies. In this study, we report a continuous observation method of aerosol particles by means of a vertical Mie-scattering lidar in combination with other optical and sampling instruments operated at the ground level. In the Fernald method used for...

Urban Heat Island is usually caused by Land use Land-Cover Changes (LULCC), including in Jakarta-Indonesia. Rapid development in Jakarta causes green open space to decrease and increase surface temperature in urban areas. In addition, Urban Heat Island also affects the spread of pollutants due to increased turbulence. Therefore, this study aims to...

Aerosols play an important role in the Earth’s radiation budget through the reflection of incoming solar radiation and formation of cloud droplets working as cloud condensation nuclei. The understanding on aerosol optical properties in troposphere, especially their behavior near the ground level, is still insufficient for precise evaluation of thei...

Population growth and urbanization will impact on city development through constructions of buildings, parking lots, streets, highways and driveways. These changes lead to the Urban Heat Island (UHI), which is an important factor for future urban planning. In this context, mesoscale climate models such as the Weather Research and Forecasting (WRF)...

Pemanasan global atau yang dikenal " global warming " , tidak asing terdengar di telinga kita. Hal ini sering dibicarakan setelah dampak dari fenomena tersebut dirasakan oleh masyarakat. Di Indonesia, banyak terjadinya bencana banjir, kebakaran hutan, merebaknya wabah penyakit menular, dan musim yang tak menentu disinyalir merupakan imbas pemanasan...

Remote sensing reflectance and emittance data can be used to estimate various surface energy balance (SEB) components needed to characterize net radiation (Rn), soil heat flux (G), sensible heat flux (H), and latent heat flux (LE) to defined mathematically. The significance of this study is the use of Landsat ETM satellite data to estimate SEB comp...

Land use and land-cover changes (LULCC) are one of the important causes of urban climate change, often represented by urban heat islands (UHI) in megacity areas, including Jakarta-Indonesia. The purpose of this study is to investigate the influence of LULCC on the UHI phenomenon in Jakarta city by employing the remote sensing technique. This study...

Current progress of remote sensing technology capable describe the spatial scale can be used as a drought monitoring. The purpose of this research are to analyze variables used for monitoring drought such as Latent heat flux (L), Bowen Ratio (BR), Evaporative Fraction (EF), and Evapotranspiration (ET), using Surface Energy Balance (SEB) method from...

Surface Energy Balance Interface Software (SEBALIS) has been created using Visual Basic 6.0 program, which can simplify the existing system and the formulation, so as to minimize the use of software products that are commercially available. Specifically, the novel framework of SEBALIS facilitates data processing by reducing repetitive and complex t...

Urbanization and Urban development have dynamic relationship with physical environment change (usually negative). The impacts are in biochemical, epidemiological and psychological. Trees and other vegetation (Open Green Space/OPS) ameliorate local Urban Heat Island (UHI) effects through shading, evapotranspiration, and reducing summer cooling deman...

Abstrak: Perubahan penggunaan lahan dalam hal ini adalah pembangunan terutama di kota-kota besar (urban) umumnya sangat pesat, menyebabkan perubahan di segala bidang. Taman-taman kota atau lahan bervegetasi semakin berkurang sehingga fungsi untuk menyegarkan udara kota menjadi berkurang pula. Perkembangan ini mengakibatkan perubahan unsur-unsur ikl...

Penelitian ini bertujuan mengamati perubahan distribusi pulau panas perkotaan (Urban Heat Island) dan pola angin dengan memodifikasi perubahan penutup lahan dari area bervegetasi rendah menjadi lahan urban atau lahan terbuka menggunakan MM5 (Mesoscale Model version 5). MM5 adalah model non-hidrostatik area terbatas dengan koordinat sigma mengikuti...

There are two important reasons why The Urban Heat Island (UHI) was suspicious as one that responsible to increase of surface and air temperature in the end decade. First relate with investigation the decrease of diurnal temperature degree, second is lower of heating that investigate in low troposphere than surface layer. Research about UHI in the...

Abstact Urbanization is the development of cities and suburban areas like in Surabaya as a result of population growth. Land-use changes such as urbanization that was made by humans were becoming factors in the alteration of local and regional climate. The surface is typically rougher and often drier in cities, as naturally vegetated surfaces are r...
