There is a growing need to apply geospatial artificial intelligence analysis disparate environmental datasets find solutions that benefit frontline communities. One such critically needed solution the prediction of health-relevant ambient ground-level air pollution concentrations. However, many challenges exist surrounding size and representativeness limited ground reference stations for model development, reconciling multi-source data, interpretability deep learning models. This research...

Abstract Urban land use cover (LULC) change raises ambient temperature and modifies atmospheric moisture, which increases heat-related health risks in cities. Greenspace bluespace commonly coexist urban landscapes are nature-based heat mitigation strategies. Yet, their interactive effects on thermal environments rarely assessed it remains unclear how extreme events (EHEs) affect ability to regulate human comfort. Using multi-year observations from a dense observational network Madison, WI,...

Abstract The significant reduction in human activities during COVID‐19 lockdown is anticipated to substantially influence urban climates, especially heat islands (UHIs). However, the UHI variations periods remain be quantified. Based on MODIS daily land surface temperature and in‐situ air observations, we reveal a substantial decline both canopy UHIs over 300‐plus megacities China compared with reference periods. intensity (UHII) reduced by 0.25 (one S.D. = 0.22) K daytime 0.23 (0.20) at...

Abstract A comprehensive comparison of the trends and drivers global surface canopy urban heat islands (termed I s c trends, respectively) is critical for better designing mitigation strategies. However, such a remains largely absent. Using spatially continuous land temperatures air (2003–2020), here we find that magnitude mean trend (0.19 ± 0.006°C/decade, SE) 5,643 cities worldwide nearly six‐times corresponding (0.03 0.002°C/decade) during day, while former (0.06 0.004°C/decade) double...

Urbanization extensively modifies surface roughness and properties, impacting regional climate hydrological cycles. Urban effects on temperature precipitation have drawn considerable attention. These associated physical processes are also closely linked to clouds' formation dynamics. Cloud is one of the critical components in regulating urban hydrometeorological cycles but remains less understood urban-atmospheric systems. We analyzed satellite-derived cloud patterns spanning two decades...

Abstract Urban areas are known to modify the spatial pattern of precipitation climatology. Existing observational evidence suggests that can be enhanced downwind a city. Among proposed mechanisms, thermodynamic and aerodynamic processes in urban lower atmosphere interact with meteorological conditions play key role determining resulting patterns. In addition, these influenced by form, such as impervious surface extent. This study aims unravel how different forms impact patterns climatology...

Advances in remote sensing and machine learning enable increasingly accurate, inexpensive, timely estimation of poverty malnutrition indicators to guide development humanitarian agencies’ programming. However, state the art models often rely on proprietary data and/or deep or transfer methods whose underlying mechanics may be challenging interpret. We demonstrate how interpretable random forest can produce estimates a set (potentially correlated) prevalence measures using free, open access,...
