Description

This dataset has been created to overcome limitations of existing gridded products of temperature on the urban environment. It aims at offering an accurate estimate of hourly air temperatures on the top largest Urban Census areas on different climatic events (heatwave, blizzard, typical weather...) and seasons. The data consists of a set of rasters, with each raster representing 1 month of data for a given city, each layer corresponding to an hour of the month. The raster spatial resolution is 0.01°x0.01° lat/lon. This dataset has been designed for environmental epidemiology and public health studies on (extreme) temperature exposure in US cities. It can also be leveraged by urban climatologists to improve our understanding of the spatiotemporal evolution of the urban heat island with regard to the variety of city layout and climatic region in the US.
