The ERATOSTHENES CoE has acquired through EXCELSIOR project a number of high-quality atmospheric instrumentation for aerosols, clouds and solar radiation measurements, in order to conduct research at the island of Cyprus. The atmospheric sector focused on the establishment of the ground-based atmospheric remote sensing station (GBS).

The GBS as part of the Cyprus Atmospheric Remote Sensing Observatory (CARO) National Facility (NF) consolidates the necessary infrastructure to set up the aerosol and cloud remote sensing observational platforms for continuous monitoring of aerosol and clouds providing ground truthing observations and a reference station for calibration/ validation of satellite missions. The research instruments are installed within two containers. Additionally, dedicated servers for the instruments control and data processing are installed in the containers, making the GBS independent from external needs, and ready to be deployed for campaign measurements outside Cyprus.

CARO is a National Facility (NF) for remote sensing of aerosol and clouds and planned to become a ACTRIS National Research Infrastructure facility for Cyprus consisting of the aerosol remote sensing (ARS) observational platform and the cloud remote sensing (CRS) observational platform. Located in the center of Limassol, Cyprus, CARO currently operates a multiwavelength Raman LiDAR PollyXT-Cyp for aerosol profiling, a scanning Doppler LiDAR for wind profiling and the sun/sky photometer of the Aerosol Robotic Network. During 2024, the CARO facility will operate a 35 GHz cloud radar, microwave radiometer, a disdrometer and a ceilometer. As soon as both observation platforms for aerosol and cloud vertical profiling are operational, CARO will become one of the most advanced facilities placed in the EMMENA region with high interest on atmospheric composition structure.

The aerosol remote sensing instruments of the GBS contributes to the GAW network in WMO Region VI – Europe as station 0-196-0-LIM.  The station is situated in the centre of the city of Limassol and represents an urban Eastern Mediterranean European coastal site. Traffic and local dust emissions are major local sources. The station is located about 800m from the coastline of Limassol and at the North of the station in a distance of 30 km there is the Troodos Mountain (~2km height). The station is co-located with the TEPAK (0-196-0-01389) Meteorological station.

In addition to the aerosol and cloud remote sensing observational platforms, CARO includes a solar radiation station and the solar radiation network of ERATOSTHENES CoE. The energy sector is responsible for the establishment of the solar radiation stations which consists of state‐of‐the-art remote sensing facilities (solar spectroradiometers, photometers and broadband radiometers) operating fully automated 24/7.

The Cyprus Solar Network (CSN) is a ground-based network consisting of five stations designed for monitoring solar energy and solar ultraviolet (UV) radiation. These stations have been strategically selected to cover different geographical areas within the Republic of Cyprus. The central station is located in Limassol, with the other four stations located in Polis Chrysohous, Kyperounta, Athalassa, and Xylofagou.

The Limassol station serves as the calibration station for the network and is equipped with advanced instrumentation to measure various aspects of solar radiation. This station includes:

  • A Bentham DMc150 double monochromator spectrophotometer: This high-precision instrument is used for UV/VIS spectral solar irradiance measurements, providing detailed data on solar radiation across different wavelengths.
  • A radiation station: This station measures several key components of solar radiation, including shortwave downwelling irradiance components such as global, direct, and diffuse solar radiation. Additionally, it measures longwave downwelling irradiance, which is important for understanding the energy balance of the Earth’s surface.
  • Erythemal UV irradiance measurement: This specific measurement focuses on the UV radiation relevant to human skin and eye health, providing valuable information for assessing potential sunburn and other UV-related health effects.
  • A sky imager: The sky imager is used to monitor cloud coverage, allowing for a better understanding of how cloud conditions impact solar radiation and aiding in the prediction of solar energy generation under varying weather conditions.
  • A calibration system: To ensure the accuracy and reliability of measurements, the station employs a calibration system with three PTB Transfer Standard Lamps. These lamps serve as traceable standards and are used for the calibration of the spectrophotometer, maintaining the high quality of the measurements.

The other four stations (Polis Chrysohous, Kyperounta, Athalassa, and Xylofagou) primarily provide measurements of global shortwave downwelling irradiance and erythemal UV irradiance.
