Night time cooling has become an important measure of quality of life during ever frequent summer heat waves - especially in urban areas. Even populations of cities with the highest quality of living, like Vienna, Austria, can suffer during strong heat waves. The debilitating effects felt in areas of persistent night time heat and livable cooler areas are unevenly distributed within and around the city. Our latest model uses zonal cooling rates and simulates density gradient driven flows induced by topography inclination. In short: it gives you a detailed map of the night time cooling potential and cool air pathways.
What we offer:
City scale simulation of cooling potential and cool air layer height.
A detailed map of cool air pathways.
Decision support for urban developers based on state of the art scientific methods.
Avoiding blockage of fresh air flow into dense urban areas in early planning stages.
Enabling informed decisions for agricultural and infrastructure projects.
Transparency and data sovereignty through open source software and latest publicly available models derived from earth observation data.
