UKEAP: National Ammonia Monitoring Network
What is the purpose of the network?
The National Ammonia Monitoring Network (NAMN) provides gaseous ammonia (NH3) and is monitored monthly ~ 72 sites. The network is used to quantify temporal and spatial changes in air concentrations and deposition in NH3 and NH4+ (at a subset of ~27 sites, as part of AGANet) on a long-term basis. The monitoring provides a baseline in the reduced nitrogen species (NH3 + NH4+), which is necessary for examining responses to changes in the agricultural sector and to verify compliance with targets set by international agreements.
What is measured?
Gaseous ammonia (NH3) and ammonium (NH4+).
