| 摘要： | The combined effects of increasing urbanization and climate change haveexacerbated 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 in terms ofpopulation, 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 community areas of Sacramento and create maps of urbanheat, the heat-mitigation index, and heat risk of the study period from 2016-2020.The Surface Reflectance product were used from Landsat 8 Operational LandImager (OLI) and Thermal Infrared Sensor (TIRS) and ECOsystem SpaceborneThermal Radiometer Experiment on Space Station (ECOSTRESS) thermal infraredsensor. Additionally, the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST) Urban cooling model was used to assess the impact of increased treecanopy scenarios. Urban hotspots were identified in central Sacramento and alongmajor transportation corridors such as Stockton Boulevard, while highest riskareas were identified in the community areas of Fruitridge/Broadway and NorthSacramento. This project identified these high-opportunity areas for heatmitigation to inform the City of Sacramento's General Plan. This will inform thepartners’ plans to reduce citizen risk by addressing urban heat islands. |
