Short summary

We analyzed measurements with the aim of finding relations between the surface atmosphere exchange of NH₃ and the CO₂ uptake and transpiration by vegetation. We found a high correlation of daytime NH₃ emissions with both latent heat flux and photosynthetically active radiation. Very few simultaneous measurements of NH₃, CO₂ fluxes and meteorological variables exist at sub-diurnal timescales. This study paves the way to finding more robust relations between the NH₃ exchange flux and CO₂ uptake.
