Abstract: This study sought to map the changes in land surface temperature (LST) in California from 2000 to 2016 using MODIS LST satellite imagery and also assess the impact of heat vulnerability on hospitalizations related to extreme heat exposure (such as heat stroke, heat cramps, heat exhaustion and heat syncope). The study employed principal component analysis (PCA), linear and multiple regression models and geographically weighted regression (GWR) analysis in achieving its objectives (n=58). The PCA generated three components: socio-economic (population below the poverty line, outdoor workers and population with less than high school diploma), elderly/disability (population over 64 years and population with disability). These components were used in developing a composite HVI, which was used to predict heat-related hospitalization in California between 2000 and 2016. The HVI was positively associated with heat-related hospitalization at both the global and local level, though the GWR showed statistically significant relationship for only 17 counties. The study also showed that socio-economic vulnerability contributed most to heat-related hospitalizations at the global level whereas both socio-economic and environmental vulnerability account for most of the hospitalizations at the local level. The LST maps showed some degree of variations both spatially and temporally among the various years with 2006 recording the highest temperature range between 52 °F and 163 °F.
