摘要：

How people live, work, move from place to place, consume and the technologies they use all affect heat emissions in a city which influences urban weather and climate. Here we document changes to a global anthropogenic heat flux (QF) model to enhance its spatial (30 '' x 30 '' to 0.5 degrees x 0.5 degrees) resolution and temporal coverage (historical, current and future). QF is estimated across Europe (1995-2015), considering changes in temperature, population and energy use. While on average QF is small (of the order 1.9-4.6Wm(-2) across all the urban areas of Europe), significant spatial variability is documented (maximum 185Wm(-2)). Changes in energy consumption due to changes in climate are predicted to cause a 13% (11%) increase in QF on summer (winter) weekdays. The largest impact results from changes in temperature conditions which influences building energy use; for winter, with the coldest February on record, the mean flux for urban areas of Europe is 4.56Wm(-2) and for summer (warmest July on record) is 2.23Wm(-2). Detailed results from London highlight the spatial resolution used to model the QF is critical and must be appropriate for the application at hand, whether scientific understanding or decision making.
