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

Public contribution
Definition of the

involved
Correction on the
technology used
and calibration
procedure
Informal meetings (AMS, EGU, …) and one formal meeting per year (Berlin, Vienna)
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
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 backscattering ceilometer / lidar SubWG
Depolarisation SubWG
Nitrogen Raman calibration SubWG
Others (HSRL, multiwavelength raman…)
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
