Monitoring atmospheric composition and climate, research in support of the Copernicus/GMES atmospheric service Editor(s): V.-H. Peuch, R. Engelen, A. Simmons, W. Lahoz, P. Laj, and and S. Galmarini Special issue jointly organized between Atmospheric Chemistry and Physics, Atmospheric Measurement Techniques, Earth System Science Data, and Geoscientific Model Development
With the acute societal concerns about air quality, climate change and their effects on health and ecosystems, there is an increasing need for comprehensive, reliable and fast information services on the atmospheric environment. This is also of importance for a range of policy-relevant applications at different scales, from international treaty verification to urban planning for instance. Succeeding to GEMS (Global and regional Earth-system Monitoring using Space and in-situ data) and MACC (Monitoring Atmospheric Composition and Climate), MACC-II* (MACC- Interim Implementation) is the third in a series of projects funded since 2005 through the European Union\'s Seventh Framework programme to build up the atmospheric service component of the Global Monitoring for Environment and Security (GMES) / Copernicus European programme. MACC-II combines the expertise of its 36 partner institutes from 13 European countries to bridge the gap between the meteorological and environmental communities engaged in research and operational service provision. Using the extensive experience of both communities, MACC-II provides information on atmospheric composition using satellite observations, ground-based observations, and state-of-the-art numerical models (http://www.copernicus-atmosphere.eu). MACC-II not only monitors atmospheric composition over time, but also provides forecasts of air quality, dust storms, fire emissions and solar/UV radiation for a few days ahead both globally and in more detail for Europe. Furthermore, MACC-II supports studies of pollution events and possible responses to mitigate their effects, annual assessments of air quality, and the monitoring of greenhouse gases and their sources and sinks at the Earth\'s surface. This Special Issue focuses on the world-class research aspects that underpin the continuous development, evaluation and delivery of the GMES/Copernicus services for atmospheric composition.

Corrigendum to "Decoupling the effects of clear atmosphere and clouds to simplify calculations of the broadband solar irradiance at ground level" published in Geosci. Model Dev., 7, 1661–1669, 2014
Summary: This paper presents a new operational CO2 forecast product as part of the Copernicus Atmospheric Services suite of atmospheric composition products, using the state-of-the-art numerical weather prediction model from the European Centre of Medium-Range Weather Forecasts.
The evaluation with independent observations shows that the forecast has skill in predicting the synoptic variability of CO2. The online simulation of CO2 fluxes from vegetation contributes to this skill.

Improving HelioClim-3 estimates of surface solar irradiance using the McClear clear-sky model and recent advances in atmosphere composition
Summary: The HelioClim-3 database (HC3v3) provides records of surface solar irradiation every 15 min estimated by processing images from the geostationary meteorological Meteosat satellites using climatological data sets of atmospheric properties. A method is proposed to improve a posteriori HC3v3 by combining it with data records of advanced global aerosol property forecasts and physically consistent total column content in water vapour and ozone produced by the MACC projects.
Daily global fire radiative power fields estimation from one or two MODIS instruments
Summary: This paper describes a method to correct the bias in daily fire radiative power (FRP) observations from any low Earth orbit satellite, so that that the budget of daily smoke emissions remains independent of the number of satellites from which FRP observations are taken into account. This ensures the possibility of running a system assimilating observations from several sensors, e.g. the Global Fire Assimilation System (GFAS), in case of failure of one of the MODIS instruments.
