BHP
In order to reduce population health risks due to the pollution,
nowadays it is very important to monitor chemical emissions from
chemical plants and refineries or from other pollution sources. In this
framework, BHP iron ore plant situated in Port Headland, Australia,
used an ALS300 Lidar with scan capabilities to reconstruct the 3-D
plumes evolution thanks to the fast speed velocity with a spatial
resolution of 1.5 m.
Paris Subway
In order to better characterize the dynamical processes driving the
aerosol distribution in its subway network, the RATP (Régie Autonome
des Transports Parisiens) performed two experiments at Nation station
(RER A) using an EZ AEROSOL AL300 system. The performances have
enabled to qualitatively survey the aerosol spatial distribution along
the 225 m of the platform and within the tunnel up to 360m, pointing
out the variability of the aerosol load along the platform during some
events, with high spatial (1.5 m) and time resolution (between 1s to
1mn). Such continuous monitoring of the aerosol dynamic highlights the
relative influences of particle resuspension, dispersion by the
security ventilation means, and inputs from both the passengers and
outdoor environment. These results could eventually lead to modeling
tools able to better assess both RATP users and employees exposures
according to their location and residence time in the station.
ICOS
Europe is conducting a pioneer project in order to constraint its
GreenHouse gas emissions (CO2, CH4, N20, PFC), targeting 80% of carbon
emission reduction within the next 40 years. Within the framework of
ESFRI infra-structure project, the pilot project ICOS (Integrated
Carbon Observation System) has been launched in order to create and
maintain a coordinated, integrated, long-term high resolution network
of atmospheric and ecosystem observations. During the initial platform
design phase, several lidars were deployed nearby Orleans, France, to
retrieve continuous PBL heights and aerosol structures. Under all
weather conditions, clear sky, fog, low clouds, the ALS300 has been
able to detect the different layers, residual , nocturnal and
convective, from 75m up to 2km during the whole month of October 2008.
Morevover, thanks to its 3D scanning capability, the EZLIDAR was able
to provide the variability of the PBL height around the site, enabling
the scientists to better take into account the various sources and
sinks. Comparison results between manufacturers are is expected in
2009.
