Abstract:

The mixed layer height (MLH) is an important parameter of the planetary boundary layer (PBL) because it significantly affects the transportation and dispersion processes of pollutants emitted from different sources. Its estimation can be identified by different physical indicators. Automatic lidar-ceilometers ALC) with their compact design, and the high range resolution (∼10 m) make them advantageous to many of the alternative systems for the MLH estimation.

The scope of the study is to analyze the variations of the MLH under different cloud conditions in daily and monthly basis. For this scope the data of the first five months from the Campbell ceilometer CS135 were analyzed. The instrument is operating in a rural place of Euboia Island (Greece) and the study presents preliminary results about the atmospheric profile of this area which is also related with the air transport of the largest airport in Greece (Athens airport).

In this study, we aim to analyze the temporal variations of the MLH under different cloud conditions on both daily and monthly scales. To achieve this objective, we analyzed data collected over the first five months from the Campbell ceilometer CS135. This instrument is deployed in a rural area on Euboia Island, Greece, and the study provides preliminary results regarding the atmospheric profile of this region. Importantly, the findings are relevant to understanding the air transport dynamics around the largest airport in Greece, Athens airport.
