Abstract

Within the MEDCAPHOT-TRACE program of the European Community for studying the photochem. air pollution over the Great Athens Area, we report on 3-D lidar measurements of tropospheric ozone. After a general presentation of the DIAL technique, the exptl. layout of our system which is equipped with a unique capability for real-time anal. of each individual optical backscattered signal is briefly described and its performance is assessed. The temporal evolution of the ozone concn. up to the top of the boundary layer is then followed over a few days. In particular, the first day of the photochem. smog episode is presented and commented.

Athens

Athens (ˈæθɪnz ; Athína aˈθina; Athênai (pl.) athɛ̂ːnai̯) is a major coastal urban area in the Mediterranean and it is both the capital and the largest city of Greece. With its urban area's population numbering over three million, it is also the eighth largest urban area in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence beginning somewhere between the 11th and 7th millennia BC.

History of Athens

Athens is one of the oldest named cities in the world, having been continuously inhabited for perhaps 5,000 years. Situated in southern Europe, Athens became the leading city of Ancient Greece in the first millennium BC, and its cultural achievements during the 5th century BC laid the foundations of Western civilization. During the early Middle Ages, the city experienced a decline, then recovered under the later Byzantine Empire and was relatively prosperous during the period of the Crusades (12th and 13th centuries), benefiting from Italian trade.

Acropolis of Athens

The Acropolis of Athens (; Akrópoli Athinón) is an ancient citadel located on a rocky outcrop above the city of Athens, Greece, and contains the remains of 2.5 ancient buildings of great architectural and historical significance, the most famous being the Parthenon. The word Acropolis is from the Greek words ἄκρον (akron Antisamos, "highest point, extremity") and πόλις (polis, "city"). The term acropolis is generic and there are many other acropoleis in Greece.
