Fluxes of isoprene, monoterpenes, reactive oxides of nitrogen, and nitrous oxide
| Site | Isoprene: flux at the canopy scale (10.00–16.00 h) (mg/m2/h) | Monoterpenes: flux at the canopy scale (10.00–16.00 h) (mg/m2/h) | Reactive oxides of nitrogen: flux from soils (00.00–24.00 h) (mg N/m2/h) | Reactive oxides of nitrogen: flux at the landscape scale, inferred from model (00.00–24.00 h) (mg N/m2/h) | Nitrous oxide: flux from soils (00.00–24.00 h) (mg N2-O–N/m2/h) | |

Fluxes of isoprene, monoterpenes, reactive oxides of nitrogen, and nitrous oxide from the Bukit Atur rainforest site and the Sabahmas oil palm plantation site, with an estimate of their uncertainty, their temporal variability (calculated as the standard deviation of the 30-min or hourly measurements) and the number of observations (n) on which they are based.
