This paper reports 1 year of monthly average NO 2 indoor to outdoor (I/O) concentrations measured in 10 European museums, and a simple steady‐state box model that explains the annual variation. The measurements were performed in the EU FP5 project Master (EVK‐CT‐2002‐00093). The work provides extensive documentation of the annual variation of NO 2 I/O concentration ratios, with ratios above unity in the summer, in situations with no indoor emissions of NO 2 . The modelling included the most relevant production and removal processes of NO 2 and showed that the outdoor photolysis was the probable main explanation of the annual trends in the NO 2 I/O concentration ratios.
