What have we learnt during GAW2013?• ESFRI ACTRIS (Gelsomina 

Pappalardo)• IGAC (Paul Monks)• The Swiss GAW‐support 

(Gabrieala Seiz)• WHO Air quality and health

(Heather Adair‐Rohani)• SAG and ET reports

– GHG (Ed Dlugokencky)– Ozone (Johannes Stähelin)– Precipitation chemistry (Richard 

Artz)– Reactive gases (Martin Schultz)– UV (Susana Diaz)– GURME (Greg Carmichael)– NRT (Vincent‐Henri Peuch)– WDC (Jörg Klausen)

• Airborne observations (Carl Brenninkmeijer)

• GEO (Barbara Ryan)• WIGOS (Sue Barrell)• GFCS (Deon TerBlanche)• Ash detection network (Thomas 

Werner)• Mt Simone Pyramid ABC (Sandro 

Fuzzi)• MACCII (Vincent‐Henri Peuch)• IPCC (Renate Christ)• Satellite activities (John Burrows)• Break out sessions

– Communication and outreach– QA/QC and RRR– Socio‐economic and policy 

priorities, expansion of networks– Integrated use of observations

Need to account for the human impact on the atmosphereMust establish a science integrity before it is made into services

GAW2013 has reviewed status against the five «strategic thrusts» as defined in 

WMO Strategic Plan 2012‐2015

1. Improving service quality and service delivery2. Advancing scientific research and 

applications development and implementation of technologies

3. Strengthen capacity building4. Build and enhance partnerships and 

cooperation5. Strengthen good governance

Thank you for the attention

Points in a GAW strategy 2016‐2019 • USER DRIVEN PRODUCTS: AQ, deposition, UV, dust incl

volcanic ash, climate, NWP incl seasonal weather forecasts, marine input

• TOWARDS “ONE CHAIN”: Research driven and operational observations, model development and application, and services 

• CORE GAW ACTIVITY: Doing Good Observations, not only collecting others’ 

• POLICY FACILITATION: AQ, CLRTAP, GFCS, IPCC, new global/regional alliances, and FEWER PARALLEL PROCESSES in the technical underpinning of policies

• DATA STEWARDSHIP. WIS (WIGOS). User‐data provider interaction

• FOSTER COUNTRY CONTRIBUTIONS to research, infrastructure, education, institutional building are essential

• Management structure; community of practise
