Diffusion Tubes Data
Nitrogen dioxide (NO2) diffusion tube data for monitoring locations within York - both inside and outside Air Quality Management Areas (AQMA), from 2005 onwards. Data is updated on annual basis in June.
Monthly values are raw data (not bias-corrected) and presented in ppb (parts per billion). Bias-corrected annual averages for each diffusion tube are presented in both ppb and ug/m3 (micrograms per cubic metre) and are only calculated where data capture is 75% or greater across the 12 month monitoring period.
