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

NORS data products & techniques

• Target NORS data products tropospheric and stratospheric ozone columns and

vertical profiles up to 70 km altitude

tropospheric and stratospheric NO2 columns and profiles

lower tropospheric profiles of NO2, HCHO, aerosol extinction

tropospheric and stratospheric columns of CO

tropospheric and stratospheric columns of CH4

• 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 templates

(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/) **

Data access is public

Information about the NORS project and results is available on the NORS Webpage: http://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

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

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 NO2 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

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

M. De Mazière et al. NDACC Steering Committee, 15-19/10/2012
