GAW Report, 211. Rationalizing nomenclature for UV doses and effects on humans
World Meteorological Organization (WMO) ; Commission Internationale de l'Eclairage (CIE) - WMO, 2014The document reports on current knowledge and experience within the specific field of light and lighting described and is intended to be used by the CIE membership and other interested parties. It should be noted, however, that the status of this document is advisory and not mandatory.

GAW Report, 207. Recommendations for a Composite Surface-Based Aerosol Network
Suspended particulate matter in the atmosphere, commonly known as aerosol by the technical and scientific community, plays a role in climate change, air quality/human health, ozone depletion and the long-range transport and deposition of toxics and nutrients. Aerosols have many sources ranging from sea spray and mineral dust that are mechanically generated by wind at the Earth’s surface to sulphates, nitrates and organics produced primarily by chemical reaction of gases in the atmosphere producing non-volatile products that condense to form particles. In addition, semi-volatile substances such ...
GAW Report, 204. Standard Operating Procedures (SOPs) for Air Sampling in Stainless Steel Canisters for Non-Methane Hydrocarbons Analysis
World Meteorological Organization (WMO) ; Weiß Elisabeth; World Calibration Centre for Volatile Organic Compounds (WCC-VOCs); et al. - WMO, 2012This document gives guidance for sampling of atmospheric volatile non-methane hydrocarbons (NMHCs) in whole air using electro-polished stainless steel canisters in the WMO GAW network. The described procedures are appropriate for alkanes, alkenes, alkynes, and aromatic compounds with two to six carbon atoms (C2 to C6). NMHCs with more than six carbon atoms tend to be adsorbed on the canister surfaces and may only be partially recovered. The procedures are valid for analyzing volatile alkane, alkyl and isoprene mole fractions in continental background air with mole fractio ...
GAW Report, 205. WMO/IGAC Impacts of Megacities on Air Pollution and Climate
World Meteorological Organization (WMO) ; International Global Atmospheric Chemistry project (IGAC) - WMO, 2012The World Meteorological Organization and the International Global Atmospheric Chemistry (IGAC) project have released a study of how megacities affect the climate and pollute the atmosphere. The report concludes that rapid urbanization will pose serious health risks to city dwellers unless stronger efforts are made to reduce pollution.
GAW Report, 203. The Atmospheric Input of Chemicals to the Ocean
World Meteorological Organization (WMO) ; International Maritime Organization (IMO); Food and Agriculture Organization (FAO); et al. - WMO, 2012The atmospheric input of chemicals to the ocean is closely related to a number of important global change issues. The increasing input of atmospheric anthropogenic nitrogen species to much of the ocean may cause a low level fertilization of the ocean that could result in an increase in marine 'new' productivity of up to ~3% and thus impact carbon drawdown from the atmosphere. However, the increase in nitrogen inputs are also likely to increase the formation of nitrous oxide in the ocean. The increased emission of this powerful greenhouse gas will partially offset the climate forcing impact res ...
GAW Report, 202. Workshop on Modelling and Observing the Impacts of Dust Transport/Deposition on Marine Productivity
In this report we evaluate the state-of-art knowledge and uncertainties regarding the deposition of dust on the ocean and its mineralogical composition provided by models and measurement datasets. Global climate models were recently intercompared by Huneeus et al. (2011) using results from the AEROCOM model intercomparison. The deposition calculations from these global models are frequently used as input for biological productivity calculations. A model measurement comparison (Huneeus, 2011) shows that global models do reproduce the observed data over several orders of magnitude. However, the ...
GAW Report, 199. Tropospheric Ozone Changes : observations, state of understanding and model performances
This report presents an almost complete collection of extended abstracts of the oral and poster presentations of the second workshop on tropospheric ozone changes. For some presentations no extended abstract is included as their content has already been published in peer reviewed literature or manuscripts are under preparation. A summary of this workshop has been submitted as a newsletter article of the International Global Atmospheric Chemistry Project (IGAC, 2011). The original workshop presentations are available from the meeting web site at
GAW Report, 197. Addendum for the Period 2012-2015 to the WMO Global Atmosphere Watch (GAW) Strategic Plan 2008-2015
The GAW Strategic Plan serves to guide the development of the Programme during an eight year period. The present ‘WMO Global Atmosphere Watch (GAW) Strategic Plan: 2008-2015’, published as GAW Report No. 172, specified implementation tasks for the period 2008-2011 [WMO, 2007c]. The purpose of this document, the ‘Addendum to the GAW Strategic Plan: 2008-2015’, is to guide the work of all GAW contributors for the period 2012-2015. The general strategy for the development of the Programme, the long-term objectives, the implementation principles, and the various goals spelled out in sub-chapters o ...

GAW Report, 195. WMO/GAW Expert Workshop on Global Long-term Measurements of Nitrogen Oxides and Recommendations for GAW Nitrogen Oxides Network
World Meteorological Organization (WMO) ; Gilge S.; Plass-Duelmer C.; et al. - WMO, 2011 (WMO/TD-No. 1570)Nitrogen oxides are a component of a group of reactive gases required to be measured in the GAW Programme. The reactive gases group focuses on gases known to be intimately involved in various aspects of the chemistry of the troposphere and includes surface ozone (O3), carbon monoxide (CO), volatile organic compounds (VOCs), and sulphur dioxide (SO2), as well as oxidized nitrogen species. The sum of nitric oxide (NO) and nitrogen dioxide (NO2) has traditionally been called NOx. The sum of oxidized nitrogen species with an oxidation number >1, both organic and inorganic, is referred to as ...
GAW Report, 194. 15th WMO/IAEA Meeting of Experts on Carbon Dioxyide, other Greenhouse Gases and Related Tracers Measurement Techniques
The 15th WMO/IAEA Meeting of Experts on Carbon Dioxide, Other Greenhouse Gases and Related Tracers Measurement Techniques took place from 7 to 10 September 2009 at the MaxPlanck-Institute for Biogeochemistry in Jena, Germany. The meeting reviewed current WMO data quality objectives, covering such topics as carbon dioxide and other greenhouse gases, stable isotopes, radiocarbon in greenhouse gas measurements, calibration, quality control, data management and archiving. The experts also discussed new and emerging technologies, including measurements of greenhouse gases with high-precision spectr ...
