Universidade Estadual do Arizona apresenta ferramenta Cool Routes para trajetos com sombra

A Universidade Estadual do Arizona desenvolveu uma ferramenta online de código aberto chamada Cool Routes para ajudar pedestres a encontrar os caminhos mais frescos e sombreados em áreas urbanas. A plataforma atualmente cobre o campus de Tempe e visa combater o efeito de ilha de calor urbana que torna a caminhada perigosa em cidades quentes.

A ferramenta calcula a temperatura radiante média analisando a sombra de edifícios e árvores usando dados de alta resolução do Serviço Geológico dos Estados Unidos. Ela também incorpora previsões meteorológicas e o horário do dia para simular condições térmicas a partir de seis direções.

Isaac Buo, cientista de informática urbana na ASU que co-liderou o projeto, explicou a abordagem: "Se você estiver disposto a fazer um desvio de, digamos, dois minutos extras, podemos levá-lo por uma rota bem sombreada", disse ele.

Pesquisadores testaram os cálculos com um carrinho móvel chamado MaRTy em dias quentes de verão. A plataforma está sendo disponibilizada em código aberto para que outras cidades possam adaptá-la para o planejamento de plantio de árvores ou pontos de ônibus sombreados.

A study in PLOS Climate reports that U.S. warming trends vary sharply by state and by whether researchers look at temperature averages or extremes. Using data from 1950 to 2021 for the 48 contiguous states, the authors found that 27 states showed statistically significant increases in average temperature, while 41 showed warming in at least one part of their temperature range—such as hotter highs in parts of the West and warmer cold-season lows in parts of the North.
