National Focal Centre (NFC) for Modelling and Mapping of Exceedances of Critical Loads and Critical Levels

NFC model code calculates exceedances of Critical Loads (for acidifying and for eutrophying air pollutants) and Critical Levels (for ammonia) to generate air pollution statistics. It is used by UK and devolved governments, statutory bodies, NGOs, environmental planners and consultants:
(1) to assess progress towards statutory targets;
(2) to assess development applications; and
(3) for UK reporting to the international Coordination Centre for Effects of the Air Convention (CLRTAP).
