WMO/GAW Publications (available on-line)
- GAW Reports - Ozone Bulletins - Greenhouse gas Bulletins - Precipitation Chemistry Assessments - Ozone Assessments - Data Summaries by WDCs
GAW Focal Areas Ozone, reactive gases, greenhouse gases, aerosols, UV
radiation, precipitation chemistry, urban pollution GURME,
atmospheric deposition to the oceans with GESAMP
WMO/GAW support of GMES MACC and Sand and Dust Storm Warnings
- The WMO Sand and Dust Warning Advisory and Assessment System (SDS-WAS) with three nodes, for Europe- North Africa-Middle East, Asia and Americas
- Near-Real time delivery of data on reactive gases by several GAW stations for fast validation of MACC products
The Global Atmosphere Watch (GAW http://www.wmo.int/gaw) Programme of the World Meteorological Organization (WMO) is a partnership involving 80 countries that provide reliable long-term world-wide scientific data and information on the chemical composition of the atmosphere and related physical parameters.
The mission of GAW is to • Reduce environmental risks to society and meet the requirements of
environmental conventions; • Strengthen capabilities to predict climate, weather and air quality; • Contribute to scientific assessments in support of environmental policy through 1. Maintaining and applying global, long-term observations of the chemical
composition and selected physical characteristics of the atmosphere. 2. Emphasizing quality assurance and quality control. 3. Delivering integrated products and services of relevance to users.
GAW Central Facilities
Support quality assurance and control (QA/QC) for the benefit of both developed and developing countries, important as only data of known and adequate quality are useful:
• Central Calibration Laboratories (CCLs) • Quality Assurance/Science Activity Centres (QA/SACs) • World Calibration Centres (WCCs) • Regional Calibration Centres (RCCs) • World Data Centres (WDCs)
GAW Observations
Versatile station information is available through the GAW Station Information System GAWSIS (http://gaw.empa.ch/gawsis/).
Aircraft and satellite measurements also contribute to the global observing system, including:
UNEP/WMO Integrated Assessment of Tropospheric Ozone and Black Carbon
Quality Assurance
Actions benefit both climate change and air quality issues
• CONTRAIL project
• CARIBIC project
• IAGOS-ERI project
• National routine aircraft observations (e.g. by NOAA and JMA)
GAW training and Education Centre (GAWTEC)
GAWTEC, hosted by Germany, gives two two-week courses annually for station personnel. In the 22 courses held since 2001, about 250 station operators from 58 countries were trained on atmospheric chemical and related physical observations.
An example: Surface ozone trends at selected GAW stations
Most recent Measurement Guidelines
GAW Report 200: WMO/GAW Standard Operating Procedures for In-Situ Measurements of Aerosol Mass Concentration, Light Scattering and Light Absorption (Edited by John A. Ogren), 134 pp, October 2011
More measurements and research needed to explain regional differences in ozone trends
