Since the industrial revolution, about 375 billion tonnes of carbon have been emitted by humans into the atmosphere as carbon dioxide (CO2 ). Atmospheric measurements show that about half of this CO2 remains in the atmosphere and that, so far, the ocean and terrestrial sinks have steadily increased. Accurate measurements of atmospheric CO2 by WMO/GAW partners provide the basis for understanding the fate of CO2 that has been emitted to the atmosphere. The figure (left) shows globally averaged CO2 since 1958 inferred from measurements by GAW partners (blue) and as estimated in the absence of oceanic and terrestrial sinks (green). The figure (right) shows the

Executive summary The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mole fractions of carbon dioxide (CO2 ), methane (CH4 ) and nitrous oxide (N2O) reached new highs in 2011, with CO2 at 390.9±0.1 ppm [2] , CH4 at 1813±2 ppb [3] and N2O at 324.2±0.1 ppb. These values constitute 140%, 259% and 120% of pre-industrial (before 1750) levels, respectively. The atmospheric increase of CO2 from 2010 to 2011 is similar to the average growth rate over the past 10 years. However, for N2O the increase from 2010 to 2011 is greater than both the one observed from 2009 to 2010 and

The map above shows the erythemal UV index for clear-sky conditions as forecasted for 11 October from SCIAMACHY data. It shows a typical global distribution of the erythemal UV index with values around 14 to 16 in the equatorial region and values near zero close to the poles. However, there is a region around South Georgia which will be exposed to unusually high UV. Whereas most areas around 50°S experience a UV index between 2 and 4, South Georgia and the ocean areas to the east experienced a UV index of about 12. This is 3-6 times higher than the normal value for this latitude at this time of the year. To the left is a map of chlorophyll concentration from the SeaWifs instrument on the SeaStar spacecraft. This map shows that the region which will now be exposed to intense UV radiation is a region with large bioproduction compared to other regions of the globe and is hence particularly vulnerable to elevated UV radiation.

annual emissions in PgC [1] from fossil fuel combustion and other industrial processes, the annual atmospheric increase, and the amount of carbon sequestered by sinks each year. These sinks constitute the small net difference between large fluxes (~100 PgC per year) into and out of the atmosphere from the terrestrial biosphere and oceans. This small net difference varies with climate oscillations, such as El Niño and La Niña events. The ocean sink is less susceptible to human interference than the terrestrial biosphere. Net uptake of CO2 by the ocean makes it more acidic with potentially large impacts on the ocean food chain. (The figures and text are based on Ballantyne et al., 2012 and Levin, 2012.)

the average growth rate over the past 10 years. Atmospheric CH4 continued to increase at a similar rate as observed over the last 3 years. The NOAA Annual Greenhouse Gas Index shows that from 1990 to 2011 radiative forcing by long-lived greenhouse gases increased by 30%, with CO2 accounting for about 80% of this increase. 7 Oct. 2006

Long term observations = slow delivery  High quality atmospheric chemistry measurements meant for trend analysis need to be quality checked  Meteorological data used in weather forecasting (e.g. radiosondes) don’t need long term consistency. Raw data often deleted after a short while.  GAW and others now try to fulfil both needs: 

One stream of high quality verified data for use in Assessment and scientific work



One stream of NRT or rapid delivery data for use in model and satellite validation, publishing on the web etc.

 Many GAW reports deal with measurement guidelines, also for NRT data delivery

NRT delivery often means more work  Many data providers are obliged to submit data to several data centres, often in different formats  Pressure to deliver data also in NRT in order to be visible and relevant

GAW collaborates with a number of networks, programmes and projects. Here follow two examples: IAGOS and NORS 19

IAGOS-ERI 

IAGOS-ERI is one of the new European Research Infrastructures on the ESFRI Roadmap 2006 . It will establish and operate a distributed infrastructure for long term observations of atmospheric composition, aerosol and cloud particles on a global scale from a fleet of initially 10-20 long range in-service aircraft of internationally operating airlines.



IAGOS-ERI deploys newly developed high-tech instruments for regular in-situ measurements of atmospheric chemical species (O3, CO, CO2, NOy, NOx, H2O), aerosols and cloud particles. The data will be available in near real time to weather services and GMES service centres.



IAGOS-ERI will provide a data base for users in science and policy, including near-real time data provision for weather prediction and air quality forecasting. It will provide data for climate models, including those used in the GMES Atmospheric Service, and the carbon cycle models used for the verification of CO2 emissions and Kyoto monitoring.



Data are uploaded via GPRS immediately after landing. In the future data will be transferred in real-time during the flight over the AMDAR system

NORS 

The principal objective of the NORS project is to improve the quality and validation of the products delivered by the Copernicus Atmospheric Service (CAS), previously known as GAS (GMES Atmospheric Service), using independent ground based remote sensing data from the international Network for the Detection of Atmospheric Composition Change (NDACC). NDACC is a crossborder research network with a strong European contribution, providing high-quality reference observational data for understanding the physical / chemical state of the stratosphere and troposphere, and for assessing the impact of atmospheric composition changes on climate.



The project will demonstrate operational rapid delivery of NDACC data to CAS, including a comprehensive set of metadata and a user guide. It will also develop and implement a web-based server for providing consistent validation reports of the CAS products using the NORS data products, on an operational basis. In support of the re-analyses planned in CAS, NORS will deliver timeseries of ground-based data back to 2003.

Some recommendations 

It would help if the number of data centres and data formats could be reduced



Hard enough to sustain long term (slow delivery) measurements with funding from short term (2-3 years, typically) projects. A more sustainable funding model is needed for the long run



Even more difficult if NRT data delivery is asked for in addition to long term archiving



Extra funding is needed if one wants 24/7 readiness (e.g. volcanic ash)



IPR of data originators has to be respected 



Many data providers live under the “Publish or Perish” regime
