    dct:description """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.        \r
\r
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.\r
