1 1 GEMS Global Production System and Data Infrastructure (PRO sub-project) Sub-project manager:Adrian Simmons Sub-project partner:ECMWF

2 2 Objectives of PRO sub-project Develop global assimilation systems for greenhouse gases, reactive gases and aerosols (Year 1 …) Acquire, pre-process and monitor observations (Year 1 …) Develop web/verification infrastructure (Year 1 …) Produce trial analyses for greenhouse gases, reactive gases and aerosols (Year 2 …) Unify refined versions of assimilation systems into integrated GEMS assimilation system (Year 3) Produce extended analyses and daily forecasts (Year 3 …) Prepare for operational implementation, including real-time forecasts to support RAQ (Year 4)

5 5 GHG assimilation system & reanalysis Head-start from FP5 COCO project Have generalized model code for new GEMS variables – common to GHG, GRG and AER Implemented surface fluxes of CO 2 Have run two-month Radon forecast Generalising code for background-error constraint Jb – common to GHG, GRG and AER April

6 6 GRG assimilation system & reanalysis Head-start on O 3 from operations and ERA-40 Have generalized model code for new GEMS variables Started to address CTM coupling Generalising code for background-error constraint Jb Have extended observation processing routines to include other GRG (NO 2, SO 2, CO, CH 2 O) variables First copy O 3 observation operators. Later use averaging kernels. SBUV and SCIAMACHY O 3 retrievals assimilated

7 7 AER assimilation system & reanalysis Have generalized model code for new GEMS variables Are implementing specific aerosol parametrizations Generalising code for background-error constraint Jb Have introduced aerosol total optical depth as new observed variable Have run aerosol forecasts from climatological initial data and derived error statistics from NMC method Activity to be coordinated with Task 3 of AER sub-project

8 8 Technical observation processing Discussed generalised BUFR definition Updated Envisat-PDS to BUFR software Reviewed data availability Extracted sample MODIS aerosol, SCIAMACHY NO 2 and MOPITT CO data (all in HDF) Next: - Set up BUFR definitions, starting with sample datasets - Develop HDF-to-BUFR converter - Maintain data-availability spreadsheet

9 9 Web interface & verification tools Last task to start Basic prototype for plot display has been set up Claude Gibert will discuss capabilities and access mechanisms in Technical Session 3 Strong interaction with RAQ project; plan for verification needs developing
