We describe an Underwater Hyperspectral Imager (UHI) deployed on instrument-carrying platform consisting of two interconnected mini-ROVs (Remotely Operated Vehicle) for the mapping and monitoring Arctic macroalgal habitats in Kongsfjorden (Svalbard) during Polar Night. The mini-ROV-UHI system is easy to transport, assemble deploy from shore, even under dark, icy cold conditions can be operated ...

While temperature rises in urbanized area there is a growing concern among key decision-makers and urban planners to actively incorporate Urban Heat Island (UHI)-related considerations their development/design. However, given that the existing models (mainly physics-based) are too complex use, need for an easy-to-use decision support tool provides explicit understanding of contributions differe...

Urban heat island (UHI) is a phenomenon which may have adverse effects on our environment and stimulated as result of urbanization or land cover changes. Thermal remote sensing has been found beneficial to study the effect UHI intensity. This paper analyses variation in surface temperature (LST) with changes Varanasi city India from 1989 2018 using Landsat satellite images. A new index named He...

Green Roof (GR) is one of the most applied strategies to Mitigate Urban Heat Island (UHI) recommended for sustainable cities. This research aims examine and evaluate effect GR/UGI ratio on UHI mitigation, creating Cool (UCI). The study was carried out at Constantine, situated in East part Algeria, characterized by a semi-arid climate with high summer solar radiation intensity. An urban analysis...

The urban heat island (UHI) is an increasingly widespread phenomenon of concern to the wellbeing and health populations living in environments. SUHI (Surface UHI) directly related UHI influences its extension intensity. Satellite images thermal infrared spectral region can be used identify study SUHI. In this work, Landsat 8 TIR were acquired a medium-sized municipality Po valley northern part ...

Urbanization is known to cause ‘Urban Heat Island’ (UHI) and elevate storm runoff. However, how urbanization influences local atmospheric moisture under global warming not well-understood. By examining 140 paired urban-rural weather station data (1980–2018), this study finds significant declines in humidity or the Dry (UDI) multiple large city clusters across a climatic gradient China. Global w...

Satellite images have been widely used for urban heat island (UHI) monitoring in recent studies, among which the summer UHI has attracted more attention. However, studies based on high spatial resolution to use single-day land surface temperature (LST) analyze UHI, due low temporal resolution, is not representative of and leads incomparability time series. The can generate a series LSTs (e.g., ...

The cooling effects of urban parks, which form “Park Cool Island” (PCI), can help decrease land surface temperature (LST) and mitigate urban heat island (UHI) effects. PCI intensity largely depends on the characteristics of urban parks. The relationship between PCI intensity and urban park characteristics such as urban park size has been well documented. However, it is still unclear how urban f...
