Quality Assessment, QA
ICTC-QMF, GENEVA, SWITZERLAND, 25-27 APRIL 2006
INTENDED USE: A central function of GAW is to serve as the global long-term network for monitoring the atmosphere providinghigh quality observations for the scientific community, Governments and international organizations, and scientific assessments for formulating environment protection policies.
Data Quality Objectives, DQO
Accuracy (Trueness)PrecisionCompletenessComparabilityRepresentativeness
ICTC-QMF, GENEVA, SWITZERLAND, 25-27 APRIL 2006
To be defined by GAW Secretariate in close consultation with the data user community, SAG and data producers.
Quality Control, QC
The Data Producer (station personnel)has the primary reponsibilty for thequality (defined by DQO) of the data.
Calibration and Data Validation Checks (Cal/Val) as Descibed in QA-Plans,Standard Operating Procedures (SOPs),Data Management, Documentation, Training, etc...
ICTC-QMF, GENEVA, SWITZERLAND, 25-27 APRIL 2006
Quality Assessment, QA

forDobson Ozone Spectrophotometers
ICTC-QMF, GENEVA, SWITZERLAND, 25-27 APRIL 2006
The Dobson ozone spectrophotometer is one of the primaryinstruments in the WMO-GAW network reporting total ozone values.The measurement time series from this instrument extends back to the1920’s. The calibration scheme for the instruments in the WMO/GAWnetwork is designed to allow the ozone values from the various stationsto be comparable over space and time.
The term calibration refers to thedetermination of the instrumentalextraterrestrial constant (ETC) for acorrectly characterized DobsonInstrument.

GAW Station Information System (GAWSIS)GAWSIS is a web-based database system that
Describes WMO Member and Contributing partner observatories and their measurement programmes for the global surface-based (in situ, balloon and remote sensing) networks co-ordinated by GAW for the six groups: Ozone, UV, Greenhouse Gases, Aerosols, Selected Reactive Gases (CO, VOCs, NOy, SO2), Precipitation Chemistry as well as meteorological observations.Facilitates data discovery at the 5 GAW World Data CentresAllows access quickly to the GAW observatory information and people responsible by country, WMO region or world wide.Maps GAW stations according to variable measured, type of station, etc.Performance monitoring tool for GAW (see examples on the reverse side)

The State of Greenhouse Gases in the AtmosphereUsing Global Observations up to December 2004
Executive summaryThe latest analysis of data from the WMO-GAW Global Greenhouse Gas Monitoring Network shows that the globally averaged atmospheric carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have all reached new highs in 2004 with CO2 at 377.1 ppm, CH4 at 1783 ppb, and N2O at 318.6 ppb. These value are higher than those in pre-industrial times by 35%, 155%, and 18% respectively. Atmospheric growth rates of these gases are consistent with previous years, though CH4 growth has slowed during the past decade. The NOAA Annual Greenhouse Gas Index (AGGI) shows that from 1990 to 2004 the total atmosphericradiative forcing by all long-lived greenhouse gases has increased by 20%.
