“…In support of mitigation plans, satellite imagery in the thermal infrared (TIR) can be used as a tool to identify thermal "hot spots" and "cold spots" and correlate the state of the thermal environment to land use composition [17][18][19][20]. "Hot spots" and "cold spots" are defined as areas which consistently demonstrate higher or lower land surface temperature (LST), respectively, as compared to their surrounding areas.…”

Mitigation plans to counteract overheating in urban areas need to be based on a thorough knowledge of the state of the thermal environment, most importantly on the presence of areas which consistently demonstrate higher or lower urban land surface temperatures (hereinafter referred to as "hot spots" or "cold spots", respectively). The main objective of this research study is to develop a methodological approach for the recognition of thermal "hot spots" and "cold spots" in urban areas during summer; this is accomplished with (a) the combined use of high and medium spatial resolution satellite data (Landsat 8 and Terra-MODIS, respectively); (b) the downscaling of the Terra-MODIS satellite data so as to acquire spatial resolution similar to the Landsat one and at the same time take advantage of the high revisit time as compared to the respective one of Landsat (16 days); and (c) the application of a statistical clustering technique to recognize "hot spots" and "cold spots". The methodological approach was applied as a case study for the urban area of Athens, Greece for a summer period. Results demonstrated the capacity of the methodological approach to recognize "hot spots" and "cold spots", revealed a strong relationship between land use and "hot spots" and "cold spots", and showed that the average land surface temperature (LST) difference between the "hot spots" and "cold spots" can reach 9.1 • K.

“…The development of built-up area cause the changes in land cover, building structure material and reduction nature of surface [4]. Land cover and building structure material which use reflective properties cause increasing the value of surface albedo [5,4], emissivity, and infrared emissivity [5] of surface in the form of decreasing of vegetation affect evapotranspiration in the area [5].…”

“…Urbanisasi di Kota Yogyakarta ini menyebabkan peningkatan suhu permukaan yang mengarah kepada fenomena UHI (Brontowiyono et al, 2011). Di sisi lain, mitigasi mengenai dampak UHI menjadi isu utama dalam pembangunan kawasan perkotaan berkelanjutan (Bonafoni et al, 2017). Untuk mengetahui intensitas UHI dalam suatu kawasan perkotaan, diperlukan penelitian yang menganalisis distribusi termal dalam kawasan perkotaan.…”

Peningkatan suhu di kawasan perkotaan adalah salah satu dampak dari urbanisasi. Fenomena Urban Heat Island (UHI) merupakan salah satu akibat yang dihasilkan akibat peningkatan suhu tersebut. Diperlukan upaya untuk menilai perubahan suhu apakah dapat berbahaya bagi manusia atau tidak. Melalui pengukuran UHI, pengaruh pembangunan kota terhadap peningkatan suhu dapat diukur. Tujuan penelitian ini adalah untuk memberikan panduan ilmiah tentang perolehan intensitas dan distribusi UHI menggunakan teknik penginderaan jauh. Studi kasus yang dilakukan berada di Kota Yogyakarta, Daerah Istimewa Yogyakarta. Citra penginderaan jauh yang digunakan adalah citra Landsat 8 perekaman tanggal 24 Juni 2013, path/row 120/65. Metode ekstraksi suhu permukaan menggunakan inversi persamaan Planck dengan koreksi emisivitas dan atmosfer menggunakan radiative transfer equation. Hasil pengolahan didapatkan intensitas UHI sebesar ±2,5oC pada Kota Yogyakarta dan intensitas UHI sebesar ±3,23oC pada area yang diperluas dengan buffer 1 km dari batas Kota Yogyakarta. Hal ini menunjukkan bahwa pemilihan area penelitian untuk analisis UHI menjadi penting karena mempengaruhi nilai intensitas UHI dan distribusi UHI. Ditemukan kawasan Malioboro dan sekitarnya berpotensi kuat terjadi UHI, sehingga perlu upaya mitigasi UHI pada kawasan tersebut. Pengukuran UHI menggunakan penginderaan jauh dipengaruhi oleh hal-hal yang berkaitan dengan sistem penginderaan jauh, seperti validasi dan akurasi hasil estimasi, pengaruh atmosfer, dan perbedaan waktu intensitas puncak UHI. Metode perolehan UHI dalam penelitian ini dapat menjadi panduan ilmiah yang digunakan untuk dasar evaluasi pembangunan perkotaan untuk lebih baik.
