摘要

•Near-infrared fluorescence can help dark surfaces stay cool in the sun.•Fluorescent re-emission contributes to effective solar reflectance (ESR).•Radiometric and calorimetric methods of ESR measurement are explored.•Mitigating wind-induced noise is key to calorimetric techniques.•Rotary calorimetric instrument measures ESR with repeatability of ±0.02.
