Summary: This study investigates the variability of urban energy flux across different landcover and climate gradients in urbanized Los Angeles County, USA. The research shows that urban climates are significantly impacted by localized parameters, irrigation, and regional climate. Furthermore, schedule-based water conservation policies may reduce the cooling capacity of urban vegetation in the late afternoon, and there is a stronger negative effect of distance from the coast on latent heat flux in interior areas compared to coastal areas.

Summary: Precipitation cools the surface due to sensible heat flux, with the highest values found in the Intertropical Convergence Zone and the South Pacific Convergence Zone. The correlation between Q(P) and precipitation is not well established on land, but Q(P) can be larger than Q(SH) and Q(LH) during heavy precipitation events at shorter time scales based on in-situ buoy observations. Future research avenues related to Q(P) implications are discussed.

Summary: This paper highlights the complexity and pitfalls of thermal infrared data analysis in urban heat island studies. Authors often jump into UHI research without fully understanding the phenomenon, leading to incorrect conclusions and results. Proper correction of data, consideration of signal source area, and understanding of radiation and heat fluxes are crucial for accurate UHI studies.

Summary: The global food and water crises caused by climate warming are increasingly significant. Estimation of large-scale evapotranspiration (ET) is challenging due to various factors. In this study, a surface energy balance model (Y-SEBAL) was proposed to simulate large-scale actual evapotranspiration, which showed better performance than other existing models. The Y-SEBAL model improved the retrieval of evapotranspiration by remote sensing at the regional scale.

Summary: The Noah-MP land surface model was used to simulate the land surface processes on the Tibetan Plateau, and the distribution and changes of sensible and latent heat fluxes were analyzed. The study found that the inter-annual variations of sensible heat fluxes were larger in the central and western regions, while latent heat fluxes were larger in the eastern region. The overall trend for latent heat fluxes on the Tibetan Plateau was increasing, but with a decreasing trend since around 2003.

Summary: The study examines different concrete mix designs to improve thermal performance for energy storage at high temperatures. Various factors such as aggregate type and percentage, cementitious materials, water-cement ratio, steel fiber reinforcement, and iron oxide powder were experimentally investigated. The results showed that using siliceous aggregate with high volumetric percentage and silica fume replacement of Type I cement significantly enhanced thermal conductivity and specific heat of the concrete. Concrete mix designs with high aggregate percentages, siliceous coarse aggregate, silica fume replacement, and steel fiber reinforcement demonstrated consistent thermal performance under cyclic high temperature exposure.

Summary: The study monitored the evolution of the lava dome of Merapi volcano and found that the dome's behavior varied on different slopes, with small and frequent collapses caused by gravitational forces. This suggests that small differences in summit morphology can control dome evolution, impacting the potential for volcanic hazards.

Summary: Mt Merapi, located just north of Yogyakarta in Java, Indonesia, is one of the most active and dangerous volcanoes in the world. A recent study using seismic noise tomography revealed high velocity anomalies beneath Mt Merapi and Mt Merbabu, believed to be evidence of old lava, while a low velocity anomaly on the southwest flank of Merapi is interpreted as an active magmatic intrusion.

Summary: This study presents the largest active submarine eruption ever documented, suggesting that the massive eruption originated from hot asthenosphere at the base of a thick, old, damaged lithosphere. The findings provide insights into how deep magma reservoirs were rapidly drained through dykes and pre-existing faults in the mantle were reactivated.

Summary: This study introduces a new conceptual model combining previously studied models for geomechanical magma reservoirs and dyke-shaped conduits, along with a model for porous mush adjacent to a visco-elastic magma reservoir. The comparison with the submarine 2018 Mayotte eruption shows that a single magma reservoir cannot fully match the observed eruptive history, highlighting the importance of considering magmatic mushes in explaining long-lived basaltic eruptions.

Summary: The Causeway Coast World Heritage Site in Northern Ireland faces safety concerns due to rockfalls on its coastal cliffs. However, the high number of tourists visiting the site makes it suitable for citizen science monitoring programs. Among these approaches, Structure-from-Motion photogrammetry based on crowd-sourced photographs is advantageous as it doesn't require specific expertise. A study evaluated different methods using crowd-sourced photogrammetry to integrate citizen surveys into a landslide monitoring program at Port Ganny, part of the Giant's Causeway tourist site. The Time-SIFT method showed satisfactory reconstruction quality with a standard deviation of 8.6 cm.
