SYRSOC is an algorithm which combines measurements from ceilometer, cloud radar and microwave radiometer to calculate cloud microphysical properties. The acronym stands for "Synergistic remote sensing of clouds". SYRSOC was developed at NUI Galway and results have been published by Martucci and O'Dowd (2011), Martucci et al. (2012) and Preissler et al. (2016).

SYRSOC is applicable for single-layer nonprecipitating liquid water clouds. A simple cloud mask is used to ensure only one cloud layer is present. Precipitation periods are excluded as well. In-cloud drizzle detection is done by applying a radar reflectivity threshold. Those screening procedures can lead to gaps in the plotted results. If there are no suitable clouds, figures remain empty. The calculations are limited to clouds below 2 km.

The automatic version of SYRSOC does not use extinction at cloud base to calculate CDNC (cloud droplet number concentration). Instead, it uses radar reflectivity.

Remote Sensing at Mace Head

The Remote Sensing Division of the Mace Head Atmospheric Research Station is run by the Centre for Climate & Air Pollution Studies (C-CAPS) at NUI Galway and supported by Irish Environmental Protection Agency (EPA), Irish Aviation Authority (IAA), and Science Foundation Ireland (SFI). Remote Sensing at Mace Head also benefits from involvement in Cloudnet; European Research Infrastructure for the observation of Aerosol, Clouds, and Trace gases ACTRIS and ACTRIS-2 (grant agreement numbers 262254 and 654109); European FP7 collaborative project BACCHUS (Impact of Biogenic versus Anthropogenic emissions on Clouds and Climate: towards a Holistic UnderStanding, grant agreement number 603445); and COST action ES1303: TOPROF (Towards operational ground based profiling with ceilometers, doppler lidars and microwave radiometers for improving weather forecasts) supported by COST (European Cooperation in Science and Technology).
