Astar

In the frame work of the International Polar Year 2007. LEOSPHERE took part into the ASTAR campaign. ASTAR among a large scope of scientific experiments will help to a better understanding of arctic aerosols characteristics, using several remote sensors systems and different airborne sensors (Falcon II from DLR and Polar 2 from AWI). EZ AEROSOL LIDAR ALS300 has been deployed and used for two weeks in April 2007. It provided aerosol and cloud profiles during the campaign in Svalbard.

ARM Intercomparision Campaign In order to assess for the data quality of the EZLIDAR™ ALS450, manufactured by Leosphere, we conducted an intercomparison measurement campaign on the 23rd and 24th October 2006 at Southern Great Plains ARM site, situated in Oklahoma, United States. SGP Central Facility, located N36° 37' W97° 30' at altitude of 320 meters ASL, is providing a large number of sensors for atmospheric monitoring, among them a Micro Pulse LIDARs (MPL) type 4 from SigmaSpace and a Raman lidar at 355nm . Data measurements from the Raman lidar (RL) have been used for a quantitative evaluation of the extinction retrieval from EZ Lidar data. As a result, ALS450 retrieved data are comparable with those of RL and MPL lidar instruments.

Tiger-Z In 2008, The NASA Aerosol Robotic Network (AERONET) began a four-year project with regular intensive field campaigns, called TIGERZ, to measure aerosol microphysical and optical properties over India. Collaborating entities in India include the Department of  Science and Technology, Ministry of Earth Sciences, IIT Kanpur, IIT Kharagpur, and the Indian Space Research Organization (ISRO). India collaborators are currently holding campaigns on measuring the monsoon and thunderstorms over India: Continental Tropical Convergence Zone (CTCZ) and STORMS. The AERONET/CALIPSO campaign share existing resources (e.g., facilities, aircraft, and manpower) established for the ongoing India-sponsored campaigns and utilize instruments through other international partnerships among them with LEOSPHERE (France).

Amma An EZLIDAR was operated by Dr Patrick Chazette, researcher from the LSCE/CEA-CNRS, within the framework of the first intensive field phase of the African Monsoon Multidisciplinary Analysis (AMMA; http://amma.mediasfrance.org/) which took place in the West African Sahel during the dry season in January-February 2006 (Toussaint, 2006). This phase of AMMA was dedicated to the study of tropospheric aerosols from biomass burning and aeolian erosion which are known to be the major aerosol sources in the West African Sahel (10-18°N) in winter (e.g. Dubovik et al., 2002). The overall objective of the campaign was to characterize the aerosol mixing between biomass burning and dust aerosols. the EZLIDAR system offered the only opportunity to deploy an airborne lidar during the campaign, which in turn offered a unique opportunity to document the vertical profile of the aerosol backscatter to extinction ration in a complex environment to prepare for the CALIOP spaceborne lidar mission.
