  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. SubCommittee 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 : WG6SCOPE • 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 groupVolontary basis, nominated by each standard national org. • Manufacturers : - Christoph Munkel , Vaisala, Germany - Holger Wille, Jenoptik, Germany - Laurent Sauvage, Leosphere, France - GeorgiosGeorgoussis, Raymetrics, Greece Public lidar experts : - Gelsomina Pappalardo, IMAA, Italy - Nicolae, Dr. Doina Nicoleta, INOE, Romania • End users : - Bertrand Calpini - WMO, RodicaNitu -MetCanada, Dirk Engelbartformelyat DWD, Germany, Michel leroy, Meteofrance and others • ISO - Paul Fransioli, ANSI formelyat NOAA - LjubaWoppowa ISO secretary Woppowa@vdi.de

  6. Calendar

  7. Visual Range lidar 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. Questions on the scope of the standard • Define a specific need (if possible) • Ash? • Dust? • Biomass burning? • Others? • Technology for monitoring (sequential or parallel discussions) • - Single backscatteringceilometer / lidar SubWG • - DepolarisationSubWG • Nitrogen Raman calibration SubWG • Others (HSRL, multiwavelengthraman…)

  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
