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, 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 ...
