MACC-II Value Added products
AER: alerts, forcing, top-down emissions
GHG: CH4 inversion, CO2 , N2O
EMI: ECCAD database, GEIA initiative
FIRE: MACC GFAS use by NASA
RAD: radiation assessments, MACC-RAD system
POL: source allocation, green scenarios
Improved user access
Dedicated web interfaces for GAIA, MACC-RAD, ENS
Policy users portal
AER: Aerosol alerts
IFS AOD daily forecast > 0.5 AND = N * AOD monthly climatology 2003-2011
Vegetation fire plumes
Dust episodes
Pollution build-ups
GHG: MACC-II 'delayed-mode' CH4 inversions
http://www.gmes-atmosphere.eu/d/services/gac/delayed/ch4_flux_inversions
● half-yearly updates of global CH4 inversions provided since 07/2009
● transition SCIAMACHY (until 12/2011) ->GOSAT (since 01/2012)
-> overall good consistency (-> presentation M. Alexe)
● however, significant negative bias of MACC-II CH4 emissions / mixing ratios over
Europe
● ICOS data should be assimilated in the future
- potential to significantly increase quality of CH4 inversions over Europe
- potential use for verification purposes

Left panel: Surface ozone concentrations (µg/m3) on June 23, 2008, as
modelled by the EMEP MSC-W air quality model used in MACC-II.
Right panel: percentage contributions from different countries and areas
to air pollution within the area marked in red in the left panel.
Example: Emission scenario impact – effect of a 30%
reduction in traffic emissions (left) or residential

User interface - interaction
Service documentation / use cases / online user feedback
Simple – detailed references on products and show case users
Iteration of user requirements
traceable to user feedback
User workshops (all MACC-II, policy)
Interaction between old/new users
Open data access with simple registration
Simple documentation who are the users
User Advisory Board
Overall user feedback
Training (summer school, eLearning material)
Tied to identified user needs
Number of registered data users
MACC-II users vary from ‘power’ users (requiring daily
data) to users looking for specific data (area, time, species).
Service
Number of Users/ Requests for data
Global NRT Analyses & Forecasts
~200 users
Regional NRT Analyses & Forecasts
~125 users
Global Reanalysis
~1200 users
Solar Radiation
~1000 requests/year
Global ftp server
~ 40 users
Data access is fully open and free. Some numbers are approximate,
because user registration (name, institute/company, country) is not yet
implemented for all data servers.

Access to the emissions developed within MACC-II
ECCAD database
(ECCAD = Emissions of Atmospheric
Compounds and Compilation of Ancillary Data)
Access to a large number of inventories + tools:
- global anthropogenic: MACCity, etc.
- European anthropogenic: TNO-MACC, TNO-MACCII, etc.
- biomass burning : GFAS, etc.
- biogenic: MEGAN-MACC, etc.
Very large number of ECCAD
users (1270 from 540 institutes)
MACC-II emissions widely
used in Europe and other
Continents
standard dataset for regional AQ
modelling in Europe
The MACC-RAD information system
User access: INSPIRE / ISO Web interface + metadata

Questions to users (1)
Services and products
• Please specify for which service line(s) / parameter(s)
• Which are your operational requirements (timeliness,
reliability, availability, …)?
• How do you need information on product quality, maturity,
uncertainties?
• How would you like to receive information about system
updates, system problems, etc. (currently through a mailing
list)?
• Which information on service degradation risk do you
require (e.g. drop-out of assimilated satellite)?
Questions to users (2)
Services and products (continued)
• Which (additional) requirements do you have for data
access / interfaces (ftp, OGC, …)?
• Do you make use of the graphical products available on the
web site? If so, could they be improved?
• Are data volumes an issue?
• Do you have specific requirements for documentation?
• Do you have specific requirements for training?

Questions to users (3)
Governance
• Do you have suggestions how to best organize user
interaction in Copernicus (Atmosphere service User
Advisory Board + user workshops / overall Copernicus
User Forum + national user fora)?
• Do you have suggestions how to implement / select use
cases to demonstrate added value from the Copernicus
Atmosphere Service?
