Lidar Laboratory

Lidar Laboratory since January 2002 has been merged with Air Sea Interaction Laboratory creating a new laboratory also named Air-Sea Interaction Lab

History of the Lidar Laboratory

Lidar Laboratory in Institute of Oceanology PAS exists since January 1993. However the history of the lidar group in IO PAS is longer. It was created in the early 1980s by Prof. Andrzej Zielinski. In 1992 it bought the lidar system (FLS-12) we have been since using. The purchase was possible thanks to Committee for Scientific Research (KBN) research grant. In years 1993-2000 Dr. Jacek Piskozub was the leader of the laboratory, followed in 2001 by Asoc. Prof. Tadeusz Krol. In the last 8 years we have participated in more than 20 research cruises on R/V Oceania and more than 30 shore experiments (including 4 international, one in Duck, North Carolina). A three year research grant for lidar study of sea-surface oil pollution (1996-1998) resulted in purchasing a new lidar system FLS-UV for measuring thickness of the oil films on the surface using the attenuation of water Raman scattering.

The lidar is placed on an old-but-faithful East-German Robur truck (scrapped in 1998) during a BAEX experiment in Lubiatowo on the Polish stretch of the southern Baltic shore. The simple mirror device attached to the truck enables vertical sounding of the atmosphere. Horizonthal and sloped profiles are made by tilting the lidar device itself.


The Lidar

We use a dual purpose FLS-12 lidar built in Estonia by LDI Ltd.

The lidar on s/y Oceania cruise in South Baltic. The laser and the telescope are aimed at an open porthole. The beam is aimed to zenith or to sea-surface by a mirror placed outside the porthole.


The lidar uses a tunable dye-laser pumped by eximer laser. The reciving block consists of a 200 mm diameter telescope and two interchangable blocks:

Our Output

Here is an example of aerosol concentration map. The lidar measurements were done in Lubiatowo, Poland during a BAEX-2 international experiment.


Aerosol distribution map
Picture: Aerosol concentration map (14.5 kB)


An interesting example of the field of aerosol concentration calculated from our measurements is shown above. The measurements were done with the lidar standing 60 m from the shore. The wind blew with 2 m/s velocity from the land. The dropping out of land aerosol can be clearly traced. An aerosol plume is visible about 100 m over the sea. The increasing values over 450 m from lidar are caused by due marine aerosol generation.
