EC4MACS update and recent
developments in the GAINS model
UNECE TFEIP Expert Panel on Emission Projections
Dublin, Ireland, 25 October, 2007
Outline
• What is EC4MACS
• Recent updates of GAINS within the EC4MACS
The EU-LIFE project EC4MACS:
European Consortium for Modelling of Air Pollution and
Climate Strategies
• EU funding for a consortium of integrated assessment
modelling teams to prepare and maintain modelling tools
for air quality and climate policy development

IIASA (CIAM) - Coordinator
MNP/RIVM (CCE) - critical loads data
NTUA Athens – energy projections
Uni Bonn et al. – agricultural projections
LTUA Thessaloniki – transport modelling
AEAT et al. – benefit assessment
MET.NO (MSC-W) – dispersion modelling
Supported by additional contracts for JRC Ispra and Sevilla
• Project time frame 2007-2012
• ~4.5 million € EU contribution (on co-funding basis)
Interface PRIMES-GAINS
• Expert system has been developed to transfer data from
PRIMES to GAINS
• The rules have been discussed and agreed between the
teams
• The interface allows for consistent transfer of data from
PRIMES to GAINS
• The system uses additional sets of rules to complete the
GAINS database (where PRIMES data is missing or not
available) based on existing GAINS data assuring overall
consistency with PRIMES.
GAINS impact module developments
• The mapping capabilities of the model have been updated
and extended to include:
– Exceedance maps for euthrophication and acidification
– YOLLs (Years Of Life Lost) maps
– Acidification will be completed soon
Interface CAPRI/CAPSIM-GAINS
• The projections of agricultural activity data (livestock
numbers, fertilizer use) and cost data on certain nontechnical measures have been already exchanged in the
past.
• In order to assure consistent and trouble free exchange we
are working towards development of an interface that
would allow to perform such exchange on regular basis.
Building new agricultural module of RAINS/GAINS
[1]
The sub-model to calculate gaseous emission, runoff and
leaching in a consequent way using the mass balance
approach:
• A mathematical framework to model the flow of:
– Nitrogen (NH3, N2O, NOx, N2 emissions)
– Volatile solids (CH4 emission)
• Moreover:
– Nitrogen is split up into TAN (total ammoniacal nitrogen),
which is the active part that gives rise to the gaseous
emissions, runoff and leaching and an inactive part Norg
(organic nitrogen)
Building new agricultural module of RAINS/GAINS
[2]
• The model is set-up to incorporate new emission
processes, such as emission from e.g.
–
–
–
–
Yards (e.g., hard-standings or exercising, feeding yards)
Different stages of biogas plants
Direct spread (from housing directly to the field)
Drying cow dung (e.g. India)
• Moreover it will:
– Include NO3- leaching and runoff
– Give output for smaller areas (NUTS2, NVZ)
– Give the possibility to calculate seasonal variation
