Studying Desert Dust from the Sahara and the Middle East using the Cyprus Atmospheric Remote Sensing Observatory over Limassol, Cyprus

Abstract
The Eastern Mediterranean basin is frequently affected by mineral dust air masses originating
from major desert dust regions such as the Sahara and the Middle East, transported by synopticscale
meteorological systems. The primary objective of this study is to examine and characterize
desert dust intrusions over Limassol, utilizing observations of the Cyprus Atmospheric Remote
Sensing Observatory (CARO), a National Facility operated by the Eratosthenes Centre of
Excellence. CARO NF, as an ACTRIS station, provides quality controlled and assured datasets.
This study focuses on the detailed analysis of selected dust events over Limassol. A multiparameter
aerosol typing scheme which relies on the intensive and extensive aerosol properties
retrieved from PollyXT Raman-Polarization lidar is used for the characterization of the aerosol
layers. This active remote sensing instrument has been operating continuously since October
2020, providing vertically resolved measurements of aerosol optical properties. The analysis is
complemented by the AOD and inversion products from the CIMEL sun/sky photometer at the
CUT-TEPAK site, which is part of the Aerosol Robotic Network (AERONET) network. The
synergetic dataset of lidar and sun-photometer observations enables the characterization of the
upcoming dust layers with high spatiotemporal resolution. These observations provide constraints
on aerosol classification, support the validation of dust transport models and satellite products.
