1 International standard for aerosol lidar Laurent Sauvage and George Georgoussis On behalf of the whole expert group ISO TC146/SC5/WG6

2 ISO TC146 Air quality objectives Standardization of tools for air quality characterization of emissions, workplace air, ambient air, indoor air, in particular measurement methods for air pollutants (particles, gases, odours, micro-organisms) and for meteorological parameters, measurement planning, procedures for Quality Assurance/Quality Control (QA/QC) and methods for the evaluation of results including the determination of uncertainty. Excluded: the establishment of limit values for air pollutants; the air quality in clean rooms; radioactive substances.

3 Sub Committee 5: Meteorology Elaboration of standards in the field of meteorological measurements and analyses that are focused on, but not limited to, air quality programs. The meteorological standards may include identifying: The initial standards being developed are focused on basic surface-based and remote-sensing instrument system descriptions and test methods. Further work is planned in standardizing observation systems and analytical methods and models that have general meteorological applications. Other planned work includes promoting standardization of new measurement and analysis techniques.

4 Visual range lidar standard : WG6 SCOPE measurements for the determination of direction-dependent meteorological optical range (MOR) Visibility measurements applied to lidars quantitative determination of the meteorological optical range is limited to 30 m < MOR < 2000 m.

5 WG6 : the lidar group Volontary basis, nominated by each standard national org. Manufacturers : - Christoph Munkel, Vaisala, Germany - Holger Wille, Jenoptik, Germany - Laurent Sauvage, Leosphere, France - Georgios Georgoussis, Raymetrics, Greece Public lidar experts : - Gelsomina Pappalardo, IMAA, Italy - Nicolae, Dr. Doina Nicoleta, INOE, Romania End users : - Bertrand Calpini - WMO, Rodica Nitu -MetCanada, Dirk Engelbart formely at DWD, Germany, Michel leroy, Meteofrance and others ISO - Paul Fransioli, ANSI formely at NOAA - Ljuba Woppowa ISO secretary

6 Calendar Stage name Product nameAcronymVisual range lidar standard Preliminary stagePreliminary work item (project)PWI Proposal stageNew proposal for a work itemNPJan.2007 Preparatory StageWorking draft(s)WDJan.2008 Committee StageCommittee draft(s) CD May 2010 Proposal to DIS ballot Enquiry stageDraft International Standard DIS Approval stageFinal draft International Standard FDIS Publication stage International StandardIS

7 Visual Range lidar First discussions on New proposal 2007 Receiving comments from met agencies /WMO Finalisation of Preparatory document End 2009 Proposal to DIS ballot May 2010 Enquiry stage Early 2011 Public contribution Definition of the meteorological parameters involved Correction on the technology used and calibration procedure Informal meetings (AMS, EGU, …) and one formal meeting per year (Berlin, Vienna)

8 NEXT STEP We consider there is a need of standard for « Aerosol monitoring using lidars » Need for expression of interest from the community (WMO ?) Survey of existing national work (VDI/DIN, other?) Coordination with ICAO action Use of GALION expertise

9 Define a specific need (if possible) – Ash? – Dust? – Biomass burning? – Others? Technology for monitoring (sequential or parallel discussions) - Single backscattering ceilometer / lidar SubWG - Depolarisation SubWG -Nitrogen Raman calibration SubWG -Others (HSRL, multiwavelength raman…) Questions on the scope of the standard

10 THANK YOU FOR YOUR ATTENTION Your contribution essential for the community to provide this lidar standard ! Common benefit for the industry (operational agencies,AA, Met agencies…) and for the Research QUESTIONS WELCOME
