Due to the scarcity of air temperature (Ta) observations, urban heat studies often rely on satellite-derived Land Surface Temperature (LST) characterise near-surface thermal environment. However, there remains a lack quantitative understanding how LST differs from Ta within areas and what are controlling factors their interaction. We use crowdsourced measurements in Sydney, Australia, combined with landscape data, Local Climate Zones (LCZ), high-resolution satellite imagery, machine learning...
Anthropogenic activity is now recognised as having profoundly and permanently altered the Earth system, suggesting we have entered a human-dominated geological epoch, 'Anthropocene'. To formally define onset of Anthropocene, synchronous global signature within geological-forming materials required. Here report series precisely-dated tree-ring records from Campbell Island (Southern Ocean) that capture peak atmospheric radiocarbon (14C) resulting Northern Hemisphere-dominated thermonuclear...
Reversing the field Do terrestrial geomagnetic reversals have an effect on Earth's climate? Cooper et al. created a precisely dated radiocarbon record around time of Laschamps reversal about 41,000 years ago from rings New Zealand swamp kauri trees. This reveals substantial increase in carbon-14 content atmosphere culminating during period weakening magnetic strength preceding polarity switch. The authors modeled consequences this event and concluded that minimum caused changes atmospheric...
Abstract Accurately predicting weather and climate in cities is critical for safeguarding human health strengthening urban resilience. Multimodel evaluations can lead to model improvements; however, there have been no major intercomparisons of urban‐focussed land surface models over a decade. Here, Phase 1 the Urban‐PLUMBER project, we evaluate ability 30 simulate energy fluxes atmospheric meteorological air quality simulations. We establish minimum upper performance expectations...
The spatial variability of land cover in cities results a heterogeneous urban microclimate, which is often not represented with regulatory meteorological sensor networks. Crowdsourced networks have the potential to address this shortcoming real-time and fine-grained temperature measurements across cities. We use crowdsourced data from over 500 citizen weather stations during summer Sydney, Australia, combined 100-m Local Climate Zone (LCZ) maps explore intra-urban variabilities air...
Abstract. Accurate representation of the turbulent exchange carbon, water, and heat between land surface atmosphere is critical for modelling global energy, carbon cycles, both in future climate projections weather forecasts. We describe a Model Intercomparison Project (MIP) that compares flux predictions around 20 different models provided with in-situ meteorological forcing, evaluated measured fluxes using quality-controlled data from 170 eddy-covariance based tower sites. Several...
This is a comment to the paper "Magnitude of urban heat islands largely explained by climate and population" Manoli et al. (2019, Nature 573 p. 55-60; https://doi.org/10.1038/s41586-019-1512-9)
Abstract Heatwaves have implications for human health and ecosystem function. Over cities, the impacts of a heatwave event may be compounded by urban heat, where temperatures over area are higher than their rural surroundings. Coastal cities often rely upon sea breezes to provide temporary relief. However, topographic features contributing development Foehn-like conditions can offset cooling influence breezes. Using convection-permitting simulations (⩽4 km) we examine potential both...
Abstract. A total of 20 urban neighbourhood-scale eddy covariance flux tower datasets are made openly available after being harmonized to create a 50 site–year collection with broad diversity in climate and surface characteristics. Variables needed as inputs for land models (incoming radiation, temperature, humidity, air pressure, wind precipitation) quality controlled, gap-filled prepended 10 years reanalysis-derived local data, enabling an extended spin up equilibrate conditions. For both...
The urban canopy layer (UCL) exhibits complex, heterogeneous flow patterns shaped by geometry. Traditionally, research has relied on microscale simulations over limited and often idealized building arrays, leaving a need for more extensive datasets to capture the dynamics across diverse neighborhoods. Responding this gap, we developed an dataset, known hereafter as UrbanTALES, based state-of-the-art Large Eddy Simulations (LES) 538 layouts (generated using 3,000,000 CPU hours 35 TB of...
Abstract. Occupying about 14 % of the world's surface, Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling Antarctic ice-sheet dynamics. Unfortunately, high interannual variability dearth instrumental observations before 1950s limits our understanding how marine–atmosphere–ice domains interact on multi-decadal timescales impact anthropogenic forcing. Here we integrate climate-sensitive tree growth with atmospheric southwest Pacific subantarctic islands...
Abstract The urban heat island (UHI) effect exacerbates near‐surface air temperature ( T ) extremes in cities, with negative impacts for human health, building energy consumption and infrastructure. Using conventional weather models, it is both difficult computationally expensive to simulate the complex processes controlling neighbourhood‐scale variation of . We use machine learning (ML) bias correct downscale predictions made by Met Office operational regional forecast model (UKV) 100 m...
High-quality climate information tailored to cities' needs assists decision makers prepare for and adapt change impacts, as well support the transition toward resilient cities. During last decades, two main modelling approaches emerged understand analyse urban generate information. Firstly, meso- microscale models commonly resolve street city scale (1m 1km) through simulating short "weather" type episodes, possibly under conditions. Secondly, regional (RCMs) are currently approaching...
Abstract Urban Land Surface Models (ULSMs) simulate energy and water exchanges between the urban surface atmosphere. However, earlier systematic ULSM comparison projects assessed balance but ignored balance, which is coupled to balance. Here, we analyze representation in 19 ULSMs participating Urban‐PLUMBER project using results for 20 sites spread across a range of climates form characteristics. As observations most fluxes are unavailable, examine closure, flux timing, magnitude with score...
Abstract Social, technological and climatic changes will transform the way energy is consumed over 21st century, with important implications for networks greenhouse gas emissions. Here, we develop a method to efficiently explore climate-energy interactions under various scenarios of climate, urban infrastructure change. We couple Urban Climate Energy Model Conformal Cubic Atmospheric as full-height single column driven series global climate model simulations in an ensemble approach. The...
Abstract. The New Zealand subantarctic islands of Auckland and Campbell, situated between the subtropical front Antarctic Convergence in Pacific sector Southern Ocean, provide valuable terrestrial records from a globally important climatic region. Whilst show clear evidence past glaciation, timing mechanisms behind Pleistocene environmental climate changes remain uncertain. Here we present multidisciplinary study – including marine geomorphological surveys, extensive analyses sedimentary...
In urban climate studies, datasets used to describe characteristics have traditionally taken a class-based approach, whereby areas are classified into limited number of typologies with resulting loss fidelity. New becoming increasingly available that the three-dimensional structure cities at sub-metre micro-scale resolutions, resolving individual buildings and trees across entire continents. These can be accurately determine local without relying on classes, but their direct use in numerical...
Cities are unique environments where anthropogenic waste heat from energy consumption changes the dynamics of boundary layer, affecting temperatures, pollution dispersion and buoyancy‐driven flows. Although urban important for societal wellbeing, there relatively few models that link predictions variability with climate interactions. This study presents Urban Climate Energy Model (UCLEM): a new physically based model representing transfer processes between atmosphere, external internal...
