8 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 8 Motivations for GEMS BETTER OPERATIONAL SERVICES Excess deaths in summer 2003:- 18K in France, 35K in western Europe. Europe needs improved operational warnings for Meteorological / Air-quality natural disasters GEMS will provide such warnings SCIENCE GEMS will synthesise all available data into accurate ‘status assessments’. GEMS products will facilitate study of many science questions on the sources, sinks transport, and processing of atmospheric trace constituents, TREATY ASSESSMENT & VALIDATION Conventions (Kyoto, Montreal, LRTAP) and IPCC need best estimates of sources/ sinks/ transports of atmospheric constituents. GEMS will meet the needs in a comprehensive manner, including the requirements of the GCOS Implementation Plan

9 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 9 Objectives of GEMS Global operational system for monitoring & forecasting composition ready by 2009 Combine remotely sensed and in-situ data GREENHOUSE GASES (initially including CO 2, and progressively adding CH 4, N 2 O, plus SF 6 and Radon to check advection accuracy), REACTIVE GASES (initially including O 3, NO 2, SO 2, CO, HCHO, and gradually widening the suite of species), AEROSOLS (initially a 15-parameter representation, later ~ 30) Support operational Regional Air-Quality Forecasts Global Retrospective Analyses Variational Inversion Techniques to estimate sources & sinks of CO 2 and other trace constituents

10 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 10 GEMS organisation GEMS is organised in 6 projects Validation Reactive Gases Greenhouse Gases Aerosol Regional Air Quality

11 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 11 GEMS: Greenhouse Gases - Global Deliverables Daily assimilation of all available satellite data (Advanced sounders, OCO, GOSAT) on CO 2, CO, CH 4, N 2 O Monthly / Seasonal variational inversions of both in- situ (e.g. flask) and satellite data to provide estimates of surface fluxes The same technology can be used to estimate surface fluxes of other atmospheric constituents

12 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 12 Motivations for the GEMS:Aerosol project Aerosols are:- An emerging issue for numerical weather prediction. Neglect of aerosol is the largest error in model clear sky radiation calculations (50W/m**2) Neglect of aerosol can lead to large errors (0.5K) in the forward calculations for advanced sounders. The aerosol element of GEMS is likely to be the first GEMS element included in the operational suite An important issue for public health and air quality (e.g. forthcoming EU directive on PM2.5) GEMS will provide global forecasts for mineral dust, marine aerosol, black carbon, sulphate aerosol.. GEMS variational estimates of aerosol sources may be of help for regulatory purposes An important issue for climate Aerosols may mitigate the impact of greenhouse gases through ‘global dimming’?

13 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 13 GEMS:AEROSOL - Global Deliverables Model and assimilate global aerosol information Instruments: MERIS, MODIS x 2, MISR, SEAWIFS, POLDER, then VIIRS on NPP, VIIRS & APM on NPOESS, Initially 15 parameters =>30 parameters Global Monitoring Global Forecasts Boundary info. for Regional models

14 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 14 GEMS: REACTIVE-GASES -Deliverables & Approach Global Deliverables Monitor the global 3D / temporal distributions, transports, sources/sinks of key species such as O 3, NO 2, SO 2, CH 2 O.. Forecast Global Chemical Weather, including UV-B Initial and boundary conditions for regional Chemical Weather and Air-Quality Forecasts. Modelling & Assimilation Approach Tight coupling of the assimilating weather model (IFS) and a Chemical Transport Model (CTM ) to maintain good advection, and good chemical profiles. Copy frequently (2-hours?) the chemical fields from the assimilating model IFS => CTM (Chemical Transport Model) Copy frequently (2-hours?) the Production and Loss rates from CTM => IFS

16 EIONET Workshop, GEMS; Vilnius October 2005 A.Hollingsworth Slide 16 GEMS: Regional Air Quality Objectives Evaluate the impact on Regional Air-Quality forecasts of global information on Long-Range Transport of Air Pollutants. Initiate routine production at, & cooperation between, national air quality forecast centres for data access, forecast comparisons & skill evaluation. Improve continental to regional scale air quality models, the statistical post- treatment of forecasts, & explore multi-model ensemble approaches. Improve our understanding of the health impacts of air quality and incorporate air quality forecast information into a health forecast. Assess the effects of global variability on regional air quality and provide background for policy evaluation and evolution.

AIRNow involves 145 partners at City, State, National, International Level AIRNow’s protocols have been carefully designed to respect the mandates and intellectual property rights of all partners. Data may only be used for agreed purposes – unvalidated data my not be used for regulatory purposes Data QC algorithms are the responsibility of the data owner Data may only be displayed in a owner-agreed format (categorical or numerical) Responsibility for official forecasts lies with the mandated authority at city, state or national level….. AIRNow is perceived as a considerable step forward in real-time Air Quality service in both Canada and USA Environment Canada Meteorological Service of Canada Environnement Canada Service Météorologique du Canada
