| 摘要： | The combined effects of increasing urbanization and changing climatic conditionshave exacerbated the urban heat island (UHI) effect and heat-related risks for citydwellers. Vulnerability to heat-related illnesses is further compounded by riskfactors such as demographics, socioeconomic status, and pre-existing healthconditions. The City of Sacramento, as California’s fastest-growing city bypopulation, is particularly invested in combatting the UHI effect. The teamcollaborated with the City of Sacramento and urban planning firm, Dyett andBhatia, on three main goals: assessing urban heat at the neighborhood scale,identifying priority areas for cooling interventions, and assessing heat risk to thepopulation. This project utilized NASA Earth observation products to identifyhotspots within the communities of Sacramento and create maps of urban heat, theheat-mitigation index, and heat risk from 2016-2020. The team used the SurfaceReflectance product from Landsat 8 Operational Land Imager (OLI) and ThermalInfrared Sensor (TIRS) and the ECOsystem Spaceborne Thermal RadiometerExperiment on Space Station (ECOSTRESS) thermal infrared sensor. Additionally,the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) urbancooling model was used to assess the impact of increased tree canopy scenarios.Urban hotspots were identified in central Sacramento and along majortransportation corridors such as Stockton Boulevard, while the highest risk areaswere identified in the communities of Fruitridge/Broadway and North Sacramento.This project identified these high-opportunity areas for heat mitigation to informthe City of Sacramento's General Plan and reduce citizen risk by addressing urbanheat islands. |
