English
Radiative cooling (RC) passively cools objects by emitting heat to space, offering a fuel-free method for climate mitigation. This study proposes a meteorological model to quantify annual RC power for ~2000 global cities, analyzing geographic disparities. It estimates CO2 emission reductions from RC deployment and defines a theoretical threshold area needed to rebalance Earth's energy budget. These findings provide a quantitative basis for guiding worldwide RC deployment against global warming.

📄 Abstract（原文）
Radiative cooling (RC) passively cools terrestrial objects by radiating heat into outer space, providing a fuel-free means for addressing energy and environmental challenges. However, its potential to mitigate global warming at the planetary scale remains unquantified. Herein, we examine global RC power on an annual time scale, which is vital for implementing RC-based technologies. We propose a meteorological data-based model and quantify the RC power across ∼2000 global cities. The geographic disparities of global RC power are analyzed. Regions with temperature reductions exceeding 6 °C and those with RC power over 80 W m –2 are highlighted. Based on the year-round cooling power, we categorize the global RC map into five representative regions. Furthermore, we estimate the CO 2 emission reduction of RC deployment and define a theoretical threshold area required to rebalance Earth's energy budget. These results provide a quantitative basis for guiding worldwide RC deployment toward global warming mitigation.
