All models contain terms for season and other long-term trend, day of week, black smoke (lag 0, 1–6, 7–12, 13–18, 19–24 and 25–30 days), temperature (modelled as a double linear relationship, lagged 0, 1–6, 7–12, 13–18, 19–24 and 25–30 days), plus interaction terms (shown; a value of “0” would indicate no interaction) defined as the products of recent temperature (lag 1–6, modelled as a continuous variable) and each of the black smoke variables (ie, assuming linear increase in black smoke effect as temperature decreases). All lag periods are included in the model simultaneously. All coefficients refer to an increase of 10 μgm−3 in black smoke concentration on only 1 day within the lag period. BS, black smoke.
