O aumento das temperaturas urbanas, associado às mudanças climáticas e à expansão da infraestrutura cinza, tem intensificado o fenômeno da ilha de calor urbana (ICU), afetando o conforto térmico em espaços externos. Este estudo caracterizou o ambiente térmico do campus da Universidade Autônoma da Baixa Califórnia em Mexicali, uma das cidades mais quentes do mundo, com o objetivo de identificar oportunidades para o planejamento de infraestrutura verde (IV). A metodologia incluiu a geração de um ortomosaico de alta resolução por meio de um veículo aéreo não tripulado para o cálculo do índice NGRDI, medições in situ da temperatura da superfície (LST) com termômetros infravermelhos e a análise geoespacial de ambas as variáveis. Os resultados mostraram temperaturas mais elevadas em superfícies impermeáveis, como o concreto e o asfalto, enquanto as áreas arborizadas apresentaram valores mais baixos. No entanto, foram identificadas zonas verdes com baixo vigor vegetal e capacidade limitada de resfriamento, o que evidencia a necessidade de fortalecer as estratégias de infraestrutura verde.
