Connections with GAS, ESA, NDACC, WMO/GAW The composition of the Steering Committee is as follows: the Project Management Team (coordinator and WP leaders); representative of MACC-II: R. Engelen a representative of ESA for the GECA environment: T. Fehr/B. Bojkov; a representative of EEA for the coordination of the in-situ component in the GMES Atmosphere area: H. Steen- Andersen G. Braathen (WMO), as co-chairman for NDACC; O. Tarasova, responsible at WMO for matters related to Greenhouse gases, Reactive gases, GAW stations and QA/QC; J.C. Lambert, as representative of CEOS WGCV

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 Reminder about NORS EU FP7 project Start: Nov. 1, 2011 Duration: 33 months Objective: To perform the required research and developments for optimizing the NDACC data for the purpose of supporting the quality assessments of the future GMES Atmospheric Service (GAS MACC-II ) To develop and implement a Web-based Validation Server of the MACC-II (GAS) products using the NORS data products

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NORS data products & techniques Target NORS data products tropospheric and stratospheric ozone columns and vertical profiles up to 70 km altitude tropospheric and stratospheric NO 2 columns and profiles lower tropospheric profiles of NO 2, HCHO, aerosol extinction tropospheric and stratospheric columns of CO tropospheric and stratospheric columns of CH 4 4 NDACC observation techniques + in-situ surface monitoring: Lidar, MicroWave, FTIR, UV-VIS DOAS + in-situ surface monitoring

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 Progress (1/2) NORS data will be HDF formatted, according to GEOMS guidelines (http://avdc.nasa.gsfc.gov/GEOMS) and NDACC instruments templateshttp://avdc.nasa.gsfc.gov/GEOMS (to be fixed asap) Rapid data delivery system is set up: All NORS data will be submitted within 1 month after acquisition to ‘NRT’ section of NDACC database (ftp://ftp.cpc.ncep.noaa.gov/ndacc/NRT/) **ftp://ftp.cpc.ncep.noaa.gov/ndacc/NRT/ Data access is public Information about the NORS project and results is available on the NORS Webpage: http://nors.aeronomie.behttp://nors.aeronomie.be

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 Progress (2/2): integrated products WP6: development of a methodology for integrating ground-based data sources to provide consistent ozone vertical distribution time series as well as tropospheric and stratospheric ozone columns at the 4 NDACC stations (NyAlesund, Alpine station (OHP), Izaña, La Réunion) 1st steps: At Alpine station (OHP, Jungfraujoch and Bern): -evaluation of validity ranges for different data sources (DIAL, FTIR, microwave); -comparisons of monthly mean profiles to identify and understand biases Next steps: Look at individual profiles and airmass variations WP5: started work on integration of surface in-situ, gb remote-sensing and satellite data

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NORS Validation Server (NVS) Goal: Web-based server for validation of GAS products using NORS data products System implementation: currently ongoing at S&T System delivery: medio 2013, deployed at BIRA WP progress/deliverables since NORS Kick-off: May 2012: User Requirements Document July 2012: Server Design Document NORS partners work closely together with the MACC-II consortium, and in particular with the MACC-II VAL project

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NVS User Requirements Identification of NORS user categories: MACC-II data originators, MACC-II VAL subproject, NORS (NDACC) data providers, MACC-II users Description of desired NORS products and MACC-II models Description of intercomparison validation chain and its parameters Description of server outputs (statistics, plots, data) Definition of use cases: Default = incremental, data-driven processing of products and generation of server outputs for fixed sets of parameter settings Interactive = user provides custom parameter settings, triggering full report generation VIP = user providing own model and/or NDACC data streams for custom report

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NVS Design
12
M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NVS Design (cont.) Server back-end retrieves model data from MACC, NORS data from NDACC; extracts and maintains metadata catalog Arrival of new products triggers incremental validation process that generates database of intermediate results and outputs Core validation chain algorithms built on top of an expanded GECA intercomparison set of command-line tools Includes tools for NO 2 diurnal correction (under development) and effective airmass calculations (already available for FTIR observations) And others in future…. Server provides web application front-end that supports all use cases: user can browse outputs, generate default reports, request custom reports
13
M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NVS Summary NVS will serve default users by generating automatically daily validation reports NVS will serve other users in interactive mode NVS will address the MACC-II products corresponding to the NORS target products, from the different MACC-II model outputs The validation chain tools will be improved gradually. NVS has been designed such as to enable expansion to more NDACC stations, more NDACC products, more model outputs. NVS will be linked to MACC-II (and NDACC ?) Webpages
14
M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 NORS near- future To start soon: Minor revision of UV/VIS GEOMS templates (for including quality indicators related to cloudy scenes) Fixing the LIDAR templates Data User documentation NDACC – TCCON (mid-IR versus near-IR) Cross- calibration of CO better characterisation of NORS data uncertainties Cf. ISSI Workshop on DIAL uncertainties Cf. Joint IRWG/NORS Workshop in Feb. 2013 First progress and review meeting at BIRA, on Nov. 20-21

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012 Some GEOMS issues GEOMS Metadata Board revived: ESA and NILU, NASA AVDC, NDACC DHF, Ian Boyd, S&T, NORS coord. Working on ‘mapping’ between GEOMS & netCDF-CF Working on verifying compliance with ISO and INSPIRE standards EVDC ESA Earth Observation Validation Data Center will be made GEOMS compliant Will be maintained for TROPOMI and Sentinels will be synchronised with AVDC for GEOMS guidelines Work in different WGs on uncertainty reporting to be stimulated
